2. General Guidelines






General Information





Following the rules

Data creators: For Vocabulary editors, contributors, and other content creators, to enter or edit data for the Getty Vocabularies, follow the Editorial Rules in this document. Contributors or other users may compare their in-house rules to the guidelines in this document to gauge compatibility. Where the rules or their application are ambiguous or not applicable to a situation at hand, please consult with the Getty Vocabulary Program, These rules are regularly updated to reflect solutions and recommendations for new issues.





Required fields and minimal records


Implementers: Developers and other implementers of the Getty Vocabularies should refer to this document to extrapolate information that will aid in understanding and presenting the Getty Vocabulary data correctly.

Among the most important guidelines are the following: Do not omit references to the sources and contributors of the Getty Vocabulary data. The Getty Vocabularies are compiled from contributors' data and this contribution should be recognized. Published sources should be cited to avoid plagiarism. In implementations, please consider including all data included in the Vocabulary record ("record" meaning all data linked directly or indirectly by a given subject_id). Do not omit flags such as "unknown" or values in display fields "undetermined." For scholarship, contributors who are adding information to the records, and others, it useful to know when a value is unknown rather than left empty. An empty field means nothing. A value such as "unknown," even if it is a default value, is in itself useful information about the status of the field and can serve to identify areas requiring additional research. See also the discussion below about how catalogers deal with information that is unknown to themselves, or unknowable in the broader context of scholarship.

VCS: The custom-built editorial system used by the Getty Vocabulary Program is called "VCS" (Vocabulary Coordination System). You may find occasional references to "VCS" in this document, for the benefit of Vocabulary Program editors or others using this particular system. The Vocabulary databases comprise relational tables and allow construction of rich data in compliance with international standards for thesauri. In addition to creating polyhierarchies, linking associative relationships, creating terms and other data in multiple languages, and other typical funtions required by a thesaurus-construction system, VCS is optimized for loading contributions, merging contributions representing the same concept, citing preferences to allow alternate points of view, and tracking revision histories over long periods of time.



Minimal record
When adding new records, create a record that meets requirements for a minimal record, which contains at minimum all required fields ("core" fields).



Fuller records
For contributions, fuller records are welcome, particularly those having useful alternate titles or names, relationships, and coreferences. Editors: When adding records or editing existing records, if there is additional time and the record is important, you may create a fuller record by filling in fields beyond the Core as time and research warrant.



Required fields
A minimum record in CONA contains a numeric ID, title or name, creator, object/work type, and other fields as described below. VCS will not allow you to save a record without the following system-required fields. Defaults are automatically provided where information is unavailable for any required field. Fields in addition to the required fields may be included as time and editorial priorities allow.

  • a numeric ID identifies the record uniquely (IDs are assigned by the system)
  • a parent (you create the link to a parent by designating the correct level by the mark "DOM" (for dominant) when you create or move a record)
  • preferred title
    • various associated flags (generally automatically assigned)
    • sources for the title
    • contributor of the title (automatically assigned by VCS)
  • creator (display creator and a link to the ULAN record for the creator)
  • catalog level
  • object type (link to AAT)
  • classification
  • location (a repository linked to ULAN, or for monumental works, a geographic location linked to TGN)
    • [for works in repositories, the unique identifier provided by the repository is required, if known]
  • creation date (display field and controlled Start and End dates)
  • subject depicted (one general term is minimum requirement, if known; specific terms are highly encouraged, if known)
  • materials (if known; display field and links to AAT for indexing)
  • dimensions (if known; display field and controlled fields for indexing)









Format and values

  • Examples in the various sections of the editorial rules illustrate the format of data in all fields.





Controlled vocabulary
Some fields use controlled vocabulary, meaning you must link to a value in a controlled list or to a record in ULAN, TGN, or AAT. If you feel additional values need to be added to the list, consult with your supervisor. Controlled vocabulary in another Getty vocabulary should be added to that vocabulary, which will allow it to be immediately available for linking to CONA.









Capitalization and abbreviation

  • In general, data in all fields should be expressed in mixed case (i.e., with the appropriate initial capitals for proper terms, but not all upper-case or all in lower case). Do not use initial capitals for titles or other fields. See further discussion under each field below.

  • Avoid abbreviations in all fields unless otherwise instructed in the appropriate rules. For terms, avoid abbreviations in the preferred term, but if there is a common abbreviation, include it as a variant term to allow retrieval.









Language of the Record





CONA is multilingual insofar as the titles and descriptive notes may be flagged in multiple languages. The preferred title in CONA is ideally in English. Differences between American English and British English should be noted where pertinent; however, variant titles in other languages are encouraged.

In some cases, the contributed data provides only a title in the local language of the repository; this title may be flagged "preferred" for the record. In other cases, a contributing institution may use an inscribed title as the preferred title, and in this way also non-English titles may be record-preferred. If a title in a language other than English is preferred for the record, an English-translation title should also be included if possible.

The flags, display dates, and other fields in the CONA record are generally in English.

Background: In a completely multilingual vocabulary, all languages would be treated equally, with none serving as a so-called dominant language. However, in practical applications, it is often necessary to treat one language as the default dominant language, particularly when the vocabulary is rich and complex. An example is CONA, in which each work record includes over 100 fields or data elements in addition to the title itself. With such vocabularies, it would be impractical to maintain the data values of flags, notes, dates, hierarchies, and other subsidiary information in several languages. For CONA, English is the dominant language, although titles and descriptive notes may be in multiple languages. In addition, if every term (title) in the original source language has not been assigned equivalents in all other target languages, the status of the other languages is not equal to that of the source language, and they are known as secondary languages according to thesuarus standards.





Preferred titles should be expressed in the Roman alphabet (if necessary, transliterated into the Roman alphabet from other alphabets or writing systems). Titles and all other information in the CONA record should be in Unicode.





CONA and IA are published in Unicode. However, in some legacy CONA data special codes may used to represent diacritics (e.g., $00).

    • Example
      [title with accent grave in display]
    • Virgin of the Host (preferred, English-P)
      La vierge à l'hostie (French-P)

  • The special diacritic codes are illustrated in Appendix A.









Production goals

  • Editors are assigned quotas for the number of records that they should complete each day. The quota differs depending upon the editorial task. Your supervisor will provide you with the target quota for the task assigned to you.

  • Typically, the quotas are gathered at the end of each month and the number of records per day is averaged over the days worked during that month. Your supervisor may tally your quota for smaller periods of time as warranted. In order to meet your quota for the month, it is recommended that you meet your quota each day rather than trying to make it up at the end of the month.









Leaving records unfinished overnight

  • Do not leave unfinished records overnight. This is particularly critical on nights when data extractions will be made for the various data releases. At the end of each day, all records in the regular, publishable sections of the hierarchy must be ready for publication.









Quality control

  • Avoid typographical errors at all costs. Proofread your work carefully.

  • If you have a tendency to make typos, for notes and other texts it is recommended to copy the note into Word, run spell check, and then paste the corrected note into VCS (but do not paste any special characters from Word).

  • Pay special attention to titles, because it is very difficult in which to spot errors in this field.









Avoid plagiarism





Published sources
Caveat: Do not copy texts from published sources verbatim! Read, analyze, and rephrase the material. Do not jump to conclusions or state more than is discussed in your sources.

  • It is permitted to use the copy function to extract texts from the Web provided you do so only as a reference. You must rewrite any such text and cite the source.

  • To avoid pasting illegal characters into VCS, first put the Web text into Notepad, and then copy it from Notepad before pasting it into VCS.

  • It is required to cite the published source of terms and the information in notes. Include the page number or other appropriate reference to the passage where you found the term or other information.

  • Sources may be linked directly to each Term and to the Descriptive Note. For other information, record the source in the overall record (called "Subject") citation designation.





It is required to include reference to the contributor who provided titles and the descriptive note. Generally, the contributor is automatically assigned when the data is loaded and the editor need not worry about it (other than to avoid deleting the contributor or misrepresenting the contribution).





What is a contributor?
A contributor to VCS is an institution or occasionally an individual person who does one of the following: 1) They use programmers to process data files that originated in their institution and they send us their data in our XML contribution format, or 2) they use our online contribution form to fill in data based on their own local data. In either case, the contributor is handling the data; their data is not being interpreted by the Vocabulary Program.

  • If an institution or person sends us hardcopy information that we in the Vocabulary Program enter into VCS, that institution or person is typically not flagged as contributor. They are considered a source for the data, but they are not a contributor because they do not physically provide data in a format that may be entered into our system. Given that there is some interpretation going on when we enter the data by hand, the Vocabulary Program is often considered the contributor in these cases.

  • To avoid misrepresenting the contributor's contribution, if you change a Title or significantly change a Descriptive Note that had been provided by a contributor, change the contributor to "VP" (for Vocabulary Program) and make a link through Source to the contributor's database. Thus, you are indicating that the contributor's data was the source for the information, but the VP has changed it or entered it.

  • Caveat: Note that you may change a Title or Creator Display contributed by a contributor only in special circumstances that have been approved by your supervisor. Normally, you should not edit a contributor's contributed Title or Creator Display. If you need to add a modified version of the Title or Creator Display, make a new Title or Creator Display with contributor "VP"; do not delete or edit the contributed Title or Creator Display unless directed to do so by your supervisor.








Uncertainty and ambiguity



Uncertainty and ambiguity in display fields

  • When important information is described as uncertain by your source, the information may still be recorded, but with an indication of uncertainty or approximation in a Descriptive Note or Display Date field (e.g., "ca." or "probably").

  • Never express more certainty than warranted by your sources. If there is disagreement among reliable sources, use terms such as probably or otherwise express the uncertainty (e.g., "Some scholars believe there is a relationship between this bronze and workshops in Rome."). Consider idiosyncrasies of contributed data (where data may have been parsed incorrectly by algorithm out of various systems) and your published sources; analyze what is true and what is only possibly or probably true.

  • Index important information in the note or display date field using appropriate indexing fields and estimating data for retrieval. See the discussion of individual Display Date and Descriptive Note fields below for more information.





Uncertainty and ambiguity in indexing fields

  • Indexing fields are intended for retrieval. Any field that contains a controlled number (e.g., Start Date) or values controlled by pick lists (e.g., Preferred flag), controlled files (e.g., Language), or links to other vocabularies (e.g., Location) are indexing fields. Consider retrieval issues when you assign terms and values to such fields.

  • When fields do not display to end-users: Some fields do not display to end-users. For example, the Start Date and End Date do not display to end-users; for these fields, estimate broadly the span of time that is applicable. Estimating too narrowly will result in failed retrieval. However, estimating overly broadly will result in false hits in retrieval.

  • When fields display to end users: Most fields in CONA are displayed to end-users. For these fields, do not make wild estimations or guess. However, if a specific value is in question, use a broader value or use both of two possible values, depending upon the circumstances. For example, in the Descriptive Note, if sources disagree about whether a style developed in 15th-century Bruges or Brussels, you could 1) state that the concept was Flemish (encompassing both Bruges and Brussels), or 2) name both cities, stating that scholars disagree regarding if the concept developed in Bruges or Brussels.

  • Knowable information: For information that is knowable but simply unknown by you, always use a more general term or omit the information. When the lack of knowledge is due to your ignorance regarding the issue, do not use terms such as "probably" or "perhaps" because this implies that scholars are uncertain of this information.

  • Debated information: For information that is unknowable because scholars disagree because the historical or archaeological information is incomplete or interpretation of the information is debated, you may use terms such as "probably" or "perhaps" to explain the ambiguity or uncertainty in a Display Date or Scope (Descriptive) Note.

  • Flags: For flags, where you must choose one value only, make the best choice based on the information at hand. If there is any doubt, consult with your supervisor. See further discussion of individual fields in the relevant chapters.





Uncertain identification of a work

  • In some cases, scholarly opinion or common usage may be divided regarding whether two titles refer to the same work; this will generally happen only with lost or destroyed works. Rely on general scholarly opinion to decide whether both titles should appear in the same CONA record or in separate records (representing separate works). When scholarly opinion is split, make them separate records, and note the possible connection in Descriptive Note and through an associative relationship. See also Associative Relationships.




Display vs. indexing

CONA often deals with differences between information intended for display and information intended for retrieval. Information for display is assumed to be in a format and with syntax that is easily read and understood by users. Such free-texts or concatenated displays may contain all the nuances of language necessary to relay the uncertainty and ambiguity that are common in art information.

In addition, CONA assumes that certain key elements of information must be formatted to allow for retrieval, often referred to as indexing in CONA. CONA advises that such indexing should be a conscious activity performed by knowledgeable catalogers who consider the retrieval implications of their indexing terms, and not by an automated method that simply parses every word in a text intended for display into indexes.

Display: In CONA, display fields are often described as free-text fields (which may be alternatively be concatenated from controlled fields, if necessary).

Indexing: Indexing fields are controlled fields. In CONA controlled fields are linked to AAT, TGN, ULAN, or a controlled list. Some fields are controlled by a simple controlled list (e.g., Classification), a link to a Getty vocabulary such as ULAN (e.g., Creator), or by consistent formatting of certain information (e.g., Earliest and Latest Dates) to ensure efficient end-user retrieval.




Specificity and Exhaustivity

Specificity: Specificity refers to the degree of precision or granularity used (e.g., campanile rather tower). However, use terms only as specific as warranted by authoritative sources. As with all indexing, it is better to be accurate and broad rather than incorrect and specific.

Exhaustivity: Exhaustivity refers to the degree of depth and breadth that the cataloger uses, often expressed by using a larger number of indexing terms or a more detailed description. However, is it useful to index every term possible? If not, where do you draw the limit? Index the most important or most prevalent characteristivs.









Merging records

  • If two records are contributed for the same work, they must be merged in VCS. The Vocabulary Program or approved surrogates may "merge" multiple records that represent the same concept.

  • In the merged record, the contributors' brief name appears with the Titles, Creator Display, and Descriptive Note that they have contributed. Other fields in the database do not link to the contributor name.

  • Caveat: Note that when you merge two records that have children in the hierarchy, all of the children will be combined in a list under the newly merged record. You must check to see if any of the children in the new list should themselves be merged.









Rules for merging





When to merge





Matching the term, parents, and meaning
Before merging, it must be ascertained that the two records actually represent the same concept. In order to be merged, CONA works must contain a title that is the same, the same location, creation date, work type, and creator.

  • Caveat re. merging: If in doubt, do NOT merge the records!


Do NOT merge facets.



Tops of Hierarchies
Do NOT merge records flagged with record type "hierarchy name."



Guide terms
Do not merge guide terms..




Procedures for merging

  • After determining that the records absolutely represent the same work, you may "merge." Go to the hierarchy view; mark DOM and REC. Mark the best, primary record as "DOM" (for dominant) and the record(s) that are to be merged into it as "REC" (for recessive). Merge using the menu.

  • Mark list: Before every merge, it is mandatory editorial practice to look at the Mark List window in order to double-check that you have marked the correct records as DOM and REC.

  • After merging, check the merged record and edit as necessary.


If, in spite of all precautions, you mistakenly merge the wrong records and you notice this error immediately, you may click "unmerge" from the menu. If some time has passed before you've noticed the mistake, if you are uncertain how to do this, or have any doubt about the "unmerge," consult with your supervisor before doing anything.






Moving records




Rules for moving



When to move records
You will generally be moving records in order 1) to put candidate records in the publishable parts of the hierarchies or 2) to change a movable work to a built work, or vice versa.




Procedures for moving

  • Determine where in the hierarchy the records belong, based on the rules in Chapter 3.1 Hierarchical Relationships. Go to the hierarchy view; mark DOM and REC. Mark the parent record as "DOM" (for dominant) and the record(s) that are to be moved under it as "REC" (for recessive). Move using the menu.

  • Mark list: Before every move, it is mandatory editorial practice to look at the Mark List window in order to double-check that you have marked the correct records as DOM and REC.

  • After moving, check the hierarchy to be sure that the move was accomplished as you intended.


Undoing a move
If, in spite of all precautions, you mistakenly move the record(s) incorrectly and you notice this error immediately, you may click "undo move" from the menu. If time has passed before you have noticed the mistake or if you have done any other editing, the "undo move" will not work and you will have to correct the hierarchy manually. If you are uncertain how to do this, or have any doubt about the "undo move," consult with your supervisor before doing anything.

      Descriptive Note:
      This work was painted when the artist was recuperating from a severe attack of mental illness; it depicts the garden at the asylum at Saint Rémy. The cropped composition, divided into broad areas of vivid color with monumental irises overflowing the borders of the picture, was probably influenced by the decorative patterning of Japanese woodblock prints. There are no known drawings for this painting; Van Gogh himself considered it a study. His brother Theo recognized its quality and submitted it to the Salon des Indépendants in September 1889, writing to Vincent of the exhibition: "[It] strikes the eye from afar. It is a beautiful study full of air and life."

    List of Fields




    About the fields

    • There are over 100 "fields" of information in a CONA record. It is unlikely that all fields of information will be available or appropriate for all concepts. However, certain information is considered core, and is required for each minimal CONA record (see also Required fields and minimal records above).

    • For some required fields, the system provides a default value, which means that this value will be used in that field unless you change it.

    • Some fields are display-only fields that are controlled by the system. For example, the Subject_ID may not be changed by the editor. It is supplied by the system according to rules in the VCS program.

    • To view the Data Dictionary, see Addendum Z.



    List of CONA Fields

    • Subject ID
      Unique numeric identification for the CONA record. Note that "subject" in this context is not the same as the depicted subject (e.g., iconography) of the work. The term "subject" has been used to refer to the record as a whole in the AAT, TGN, and ULAN, and thus is used for consistency in CONA.

      Each work in the CONA database is uniquely identified by a numeric ID that serves to link the titles/names and all other pertinent information to the work record. The ID is generally permanent. Occasionally an ID may change due to the record being merged with another record; in such cases, the new IDs are included in the licensed files, and a mapping between defunct and new IDs is provided to licensees.


      Subject ID: 700000007

    • Record Type
      Type designation that characterizes the CONA record (facet, guide term, built work, movable work, surrogate, conceptual).

      Facet: Refers to the top of a facet, which is the major division of CONA: Built Works, Movable Works, Visual Surrogatges, Conceptual Works, Unknown Named Works.

      Guide term: Also known as the node label; refers to records that serve as place savers to create a level in the hierarchy under which CONA records can be collocated. It is rarely used in CONA.

      Built Work: Refers to records in CONA that represent architecture, as defined above.

      Movable Work: Refers to records in CONA that represent items that are or could be held in repositories, as defined above.

      Surrogate: Refers to records in CONA that represent images or other surrogates for art works, not in themselves considered art works.

      Conceptual: Refers to records in CONA that represent series, multiples, or other conceptual descriptions of works that themselves are not records for the actual physical works.

    • Label
      Brief text identification of the work, concatenated from various fields in the work record. Whereas the Subject ID identifies the concept in the database, the Label serves as an easily legible heading to identify the work for end-users. It is a brief description and credit line that identifies the work and distinguishes it from similar works.


      Vincent van Gogh (Dutch, 1853-1890); Cypresses; 1889; oil on canvas; 93.4 x 74 cm (36 3/4 x 29 1/8 inches); Metropolitan Museum of Art (New York, New York, USA); Rogers Fund, 1949; 49.30.

    • Catalog level
      An indication of the level of cataloging represented by the record, based on the physical form or intellectual content of the material (e.g., item, group, subgroup, volume, collection, multiples).

    • Classification
      Placement of a work of art or architecture within a classification scheme that groups other, similar works together on the basis of similar characteristics. (e.g., Pre-Columbian art, ceramics).

    • Work Type
      The kind of object or work described (e.g., refectory table, altarpiece, portfolio, drawing, drinking vessel, basilica, dome). There are several fields associated with the repeating Work Type, including Preferred Flag, Sequence Number, Historical Flag, Display Date, and Start and End Dates.

    • Titles/Names
      Titles, identifying phrases, or names given to a work of art, architecture, or material culture. For complex works, series, or collections, the title may refer to a discrete unit within the larger entity (a print from a series, a photograph in a collection, a panel from a fresco cycle, a building within a temple complex) or it may identify only the larger entity (series, collection, cycle) itself (e.g., Venus and Cupid, Noli me tangere, Portrait of Thomas Jefferson, Ceramic fruit bowl, Untitled, Empire State Building, Album of 65 Studies). Each work may have multiple titles.


      Hagia Sophia
      Holy Wisdom
      Santa Sofia
      Agia Sofia
      Αγία Σοφία
      Sancta Sophia

    • Term ID
      Numeric ID that identifies the title/name in the database (e.g., in the example above, Hagia Sophia could have the following Term_ID: 1000000008). Term IDs are unique; homographs have different IDs. The Term_ID may be hidden from end-users.

    • Sequence order of titles/names
      Titles/names are arranged in a particular order by the editors. The preferred title or name is positioned first in a list of titles/names for the work. Implementers should sort the titles/names by the Display_order number, which is included in the data files, but typically hidden from end-users.

    • Flags for the titles/names
      In displays for the end-user, titles/names are displayed with various flags.

      Preferred Title/Name
      The flag preferred following a title/name indicates that the title/name is the so-called preferred title/name for the record. Non-preferred titles are flagged variant/alternate.

      Each record has one and only one default preferred title/name, flagged in order to provide a default term for displays (see also Language of the Titles/Names below).

      LC Flag
      Also called the AACR Flag. This flag indicates the title/name that corresponds to Library of Congress Subject Heading, for works that are listed in Library of Congress authorities (e.g., Eiffel Tower).

      NA = Not Applicable
      Y = Yes

      The title for the preferred title (MARC 150 field) should be linked to the source Library of Congress Authorities online (2002-)/2000052652. In the Page field, indicate the LC controll number (e.g, Page: sj 96005405).

      Term Type flag
      Indicates the type of term (title), based on specialized terminology used in thesauri. It is currently set to N/A in CONA.

      Historical flag
      Indicates if the title/name is current or historical.

      C = Current
      H = Historical
      B = Both current and historical
      U = Unknown
      NA = Not Applicable

      Vernacular flag
      Indicates if the title/name is in the vernacular (local) language, or some other language. Currently in CONA, most titles/names are flagged U for Undetermined. See also Language of the Titles/Names below.

      V = Vernacular
      O = Other
      U = Undetermined

      Other flags
      Flag identifying a primary characteristic of the title/name regarding the kind of title/name or its purpose. (This field maps to Title Type in CDWA.)

      brand name
      manuscript designation

      Display Title/Name flag
      Currently for most CONA records, this flag is generally set to N/A (Not Applicable).

      When used, it distinguishes titles/names intended for indexing in alphabetical lists from those in natural order intended for displays. For example, if the preferred title contains an initial article that would cause it to sort incorrectly in alphabetical lists.

         The Annunciation (display)
         Annunciation, The (index)

      For titles created or flagged as brief titles in English, intended to replace or supplement long preferred titles derived from inscriptions or othewise contributed by repositories in another language, see Types of Titles: Descriptive Titles.

      Part of Speech
      Indicates the category into which the title/name would be placed relative to its normal function in a grammatical context. Values are the following: noun, adjectival, undetermined, N/A). This flag is currently usually set to Undetermined in CONA.

    • Dates for the Titles/Names
      The date on which a particular title or name was assigned to the work, or a range of dates during which a title/name was known to be valid. The date fields comprise a Display Date, which is a note referring to a date of usage of the term, and Start Date and End Date, which are years that delimit the span of time referred to in the Display Date. Start and End Dates index the Display Date for retrieval, but are hidden from end-users.


      Display Date: 1887
      Start: 1887 End: 1887

      Display Date: late 17th century
      Start: 1675 End: 1699

      Display Date: until 1986
      Start: 1950 End: 1986

      Start and End Dates are years in the proleptic Gregorian calendar, which is the calendar produced by extending the Gregorian calendar to dates preceding its official introduction. Dates BCE are expressed as negative numbers. If the date extends to the current time, the End Date is 9999.

    • Language of the Titles/Names
      The languages for the title or name may also be included. The language designation does not necessarily mean that this is the language of the words comprising the title; instead, it means that this is the title used in publications and other contexts in a given language. A given title/name may have multiple language designations because it may have the same spelling in multiple languages.

      As of this writing, languages are derived from a controlled list, which includes the name of the language and a numeric code (e.g., British English / 70053). The code is hidden from end-users. In time, the languages will be controlled by the Language hierarchy in AAT.

      Preferred flag for a given language
      A "P" following the language in the examples indicates that this is the preferred title or name in that language.

      Language status
      Indicates if the title/name is a loan word or phrase from another language, meaning the term in one language is used with little or no change in a second language (e.g., Les Demoiselles d'Avignon is a French title that is often used in English).

    • Title/Name Qualifier
      A word or phrase used to distinguish between homographs, which are titles/names that have the same spellings but refer to different works. Qualifiers are currently rarely used in CONA. Distinctions between works with homographic titles is instead made through the use of the Label, described above.

    • Creator
      Set of fields identifying the named or anonymous individuals or corporate bodies responsible for the design, production, manufacture, or alteration of the work. Creators are indexed using Related Person/Corporate Body, which includes a link to ULAN, a Role, and optional Extent and Qualifier.

      Creator Display
      Display field expressing who was responsible for the design or manufacture of the work. It may include named or anonymous creators or patrons. If there is no known creator, this is a reference to the presumed culture or nationality of the unknown creator. Ambiguity and nuance should be expressed in this free-text display field. (e.g., Christopher Wren, attributed to Kicking Bear, follower of the Limbourg Brothers, Tintoretto with additions by unknown 16th-century Venetian).

      Related Person/Corporate Body
      One or more links to ULAN, indexing the display Creator field.

      People or corporate bodies may be indexed as related even though they are not mentioned in the Creator Display. For example, the construction company who built a structure may be indexed as a related corporate body, even though only the architect is mentioned in the Creator Display.

      The role or activity performed by a creator or maker in the conception, design, or production of a work (e.g., artist; painter; designer; draftsman; engraver; muralist; potter; modeller; sculptor; goldsmith; publisher; architectural firm).

      The part of a work contributed by a particular creator (e.g., predella; execution; with additions by; figures).

      Attribution Qualifier
      An expression of the certainty with which a work can be attributed to a known artist or group, used when the attribution is uncertain, is in dispute, when there is more than one creator, when there is a former attribution, or when the attribution otherwise requires explanation (e.g., attributed to, formerly attributed to, probably by, possibly by, workshop of, studio of, office of, atelier of, assistant to, associate of, manufactory of, follower of, circle of, school of, style of, after, copyist of, manner of).

      A concise description of the date or range of dates associated with the creation, design, production, presentation, performance, construction, or alteration of the work or its components, presented in a syntax suitable for display to the end-user and including any necessary indications of uncertainty, ambiguity, and nuance (e.g., 1667, ca. 1210, 17th century, before 952 BCE, reign of Rameses II).

      Start Date and End Date
      The earliest and latest possible dates when the work of art or architecture was created. For works that were created over a span of time, start date is the year when the work was designed or when execution was begun, and end date is the year when it was finished. For uncertain or approximate dates, these are the earliest possible years when the work could have been begun or designed.

      Date Qualifier
      A clarification of the meaning of the date, including an indication that different creative activities took place on different dates (e.g., design; execution; alteration; addition; performance; restoration; destruction; discovery; bulk; inclusive; coverage; publication).

    • Depicted Subject
      Fields recording the subject matter of a work of art (sometimes referred to as its content), which is the narrative, iconographic, or non-objective meaning conveyed by an abstract or a figurative composition. It is what is depicted in and by a work of art. It also covers the function of an object or architecture that otherwise has no narrative content. It maps to "Subject Matter" in CDWA.

      General Depicted Subject
      Indexing terms that characterize in general terms what the work depicts or what is depicted in it. This subject analysis is the minimum required. It is recommended to also list specific subjects, if possible. The controlled terms for general subject is extensible; some of the values include the following:

      advertising and commercial
      ceremonial object
      didactic and propaganda
      funerary art

      Works: Links to other works in CONA; to be used when one work depicts another, for example, if a drawing depicts a built work that is also documented in CONA.

      Iconographic Subjects: Links to the CONA Iconography Authority, for named events and characters, places, themes, and stories from religion, mythology, legend, or literature.

    • Flags for General and Specific Subjects
      General and Specific Subjects each include a number of optional flags. Values are the same for both General Subject and Specific Subject flags.

      Indexing Type
      Type of indexing represented by this subject term; a classification of the level of subject description indicated by the indexing terms, for use if necessary to distinguish between what a work is "of" and what it is "about," using the terms description, identification, and interpretation

      Description: Terms flagged description refer to generic elements depicted in or by the work. These are terms reflecting only what you would see in the subject if you did not know the specific people, event, story, or place depicted (e.g., human female, nude, column, train).

      Identification: Terms flagged identification. refer to the specific subject, including named historical, mythological, religious, fictional, or literary subjects (e.g., Leiden (Holland), Bodhisattva, Endymion, Three Graces, Madonna and Child).

      Interpretation: Terms flagged interpretation refer to the meaning or themes represented by the subjects and includes a conceptual analysis of what the work is about (e.g., salvation, original sin, sacrifice).

    Subject Extent
    Part of the object on which this particular subject is depicted, using an extensible controlled list (e.g., recto, verso, side A, side B, main panel, predella , general, overall).

    Indication if the subject depicted is preferred or a variant for this work (i.e., preferred, variant/alternate).

    Sequence Order for depicted subjects
    Sort order for the subjects depicted. Implementors should sort subjects according to these numbers within the two sets, General Subject and Specific Subject.

    Outside Iconography
    Note fields and link to a source, for subjects taken from some outside source not included in AAT, TGN, ULAN, or the CONA Iconography Authority. Fields include the Term, Code used in the outside source, and a link to the published Source and Page number of the iconography (e.g., Iconoclass or the Library of Congress Authorities).

    • Hierarchical Positions / Parent ID
      The hierarchy in CONA refers to the method of structuring and displaying the works within their broader contexts. All works are placed under a facet, Built Work or Movable Work. In addition, wholes and parts of works may be structured in a hierarchy. In the example below, a print, View of Naples, is displayed in a hiearchy as part of a volume.


      Top of CONA Hierarchy
      ....Movable Works
      ........Theatrum civitatum nec non admirandorum Neapolis et Siciliae regnorum
      ............View of Naples

      Multiple parents
      CONA is polyhierarchical. Each Subject_ID may be linked to multiple Parent_IDs. If there are multiple parents, one is marked as preferred. In displays, the preferred parent is listed first or otherwise designated. An example of when this could be used in CONA would be to link a work to its current parent and to a historical parent, of which it was formerly a part.

      Sort order in the hierarchy
      Siblings in the hierarchies are usually arranged alphabetically. However, they are sometimes arranged by another logical order, for example, in chronological order.

      Historical flag for the Parent
      Indicates if the link between the child and its parent is current or historical. Most relationships in CONA are flagged Current; however, Historical relationships may exist, as when a print is linked to a volume of which it was formerly a part.

      C = Current
      H = Historical
      B = Both current and historical
      U = Undetermined
      NA = Not Applicable


      Dates for relationship to the parent
      Dates may indicate the span of time during which a whole/part relationship existed, as when parts of a former work are now disassembled. Dates comprise a Display Date, which is a note referring to a date or other information about the link between a child and its parent, and Start Date and End Date, which are years that delimit the span of time referred to in the Display Date.

      Relationship Type for Hierarchy
      Indicates the type of relationship between a hierarchical child and its parent, expressed in the jargon of controlled vocabulary standards. Relationships in CONA are generally whole/part, as between a print and the volume that contains the print. Another example of a whole/part relationship is in TGN, Tuscany is a part of Italy. An example of genus/species relationship is calcite is a type of mineral (AAT). An example of the instance relationship is Rembrandt van Rijn is an example of a Person (ULAN).

      G=Genus/Species (generic) or BTG
      P=Whole/Part (partitive) or BTP
      I=Instance or BTI


    • Related Works
      Associative relationships to other works in CONA; they include various types of ties or connections between works, excluding whole/part (hierarchical) relationships, but including links such as those between sketches and finished works. Each reference comprises a relationship type and a link to the Subject_ID of the related work (note that "subject" in this context refers to the record, not the Depicted Subject). For end-users, the related work should be displayed with its Label.

      Relationship Type
      A term or phrase characterizing the relationship between the work at hand and the linked work. Relationship types are reciprocal (that is, linked to both records), drawn from a controlled list that comprises the controlled phrase and a numeric code, as illustrated below. The codes are hidden from end-users.


      Focus Entity

      Related Code


      related to



      distinguished from



      preparatory for

      Historical flag for the Related Work
      Indicates if the link between the related works is current or historical. Most relationships in CONA are flagged Current.

      C = Current
      H = Historical
      B = Both current and historical
      U = Undetermined
      NA = Not Applicable

      Dates for the Related Work
      Dates comprise a Display Date, which is a note referring to a date or other information about the link between the related concepts, and Start Date and End Date, which are years that delimit the span of time referred to in the Display Date. Start and End Dates index the Display Date for retrieval, but are hidden from end-users. Dates are reciprocal, meaning that they are linked to both records in the relationship.

      Start and End Dates are years in the proleptic Gregorian calendar, which is the calendar produced by extending the Gregorian calendar to dates preceding its official introduction. Dates BCE are expressed as negative numbers. If the date extends to the current time, the End Date is 9999.

    • Descriptive Note
      A narrative text or prose description and discussion of the work or group of works, including a discussion of issues related to it. Important information in this note should be indexed in other appropriate fields.

      Contributors and sources for the note should always be cited.


      [for Adoration of the Magi by Bartolo di Fredi, ca. 1400, Pinacoteca, Siena, Italy]
      The Adoration of the Magi in Siena was produced by Bartolo's workshop but probably executed primarily by Bartolo di Fredi himself. Although it is unknown where the altarpiece originally stood, the quality of the materials, large size, and the influence that the work had on other artists are all evidence of an expensive commission and prominent location, possibly in the cathedral of Siena. It illustrates the artist's late stylistic concerns and was extremely influential in Siena and elsewhere.

      [for a group of works]
      152 design drawings and models for the East Building project that I. M. Pei & Partners gave to the archives of the National Gallery of Art in 1986.

      Language for the Note
      The language of the Descriptive Note. As of this writing, most notes in CONA are written in English, however translations in other languages may be included.

    • Contributors
      The institutions or projects that contributed information to the CONA record. In order to give due credit to the contributing institution, it is required that implementers display a reference to the contributor to end-users.

      References to contributors are drawn from a controlled list comprising a numeric ID, a brief name, and a full name. The end-user must have access to the brief name and the full name. The Brief Name is the initials, abbreviations, or acronyms for the contributing projects or institutions. Contributors may be linked to the record in three ways: with the titles, with the record as a whole (called subject in this context; this is not the depicted subject), and with the note (descriptive note).

    • Sources
      The CONA record generally includes the bibliographic sources for the titles/names and the descriptive note. In order to give due credit to published sources, it is required that implementers display a reference to the published source to end-users.

      References to sources are drawn from a controlled list comprising a numeric ID, a brief citation, and a full citation. The end-user must have access to the brief citation and the full citation. Sources may be linked to the record in three ways: with the terms, with the record as a whole, and with the descriptive note.

      Page Number field
      A reference to a volume, page, date of accessing a Web site, or heading reference in a hardcopy or online source.

    • Iconography Authority (IA)
      The Iconography Authority (IA) is used to control terminology in the Depicted Subject area of a CONA record (discussed above).
