Please use the following guidelines to populate the elements:

Required: 
Fields that must be populated with data.

Conditionally Required: 
These fields are only required if you would like to take advantage of advanced search features in ARTstor

Controlled:
Fields with specific rules governing data entry as described in the cataloging guidelines.

Multiple Values:
Fields that may contain multiple values.  Values may be entered in one single element or they may be entered in multiple elements.  When entered in a single element, we suggest using a delimiter attribute to mark the beginning of one value and the next.

		<xs:annotation>
			<xs:documentation>Description: 
Name, brief biographical information, and roles (if necessary) of the named creator or creators in the design and production of the work, presented in a syntax suitable for display to the end-user and including any necessary indications of uncertainty, ambiguity, and nuance.

Guidelines: 
Use ULAN (http://www.getty.edu/research/conducting_research/vocabularies/ulan/) or, if not in ULAN, another authorized display form. The name should be in natural order, if possible. Nationality and life dates may be included. 

Examples:
a. Michel Erhart (German, ca. 1440-after 1522)
b. probably designed by Giambologna (Flemish, 1529-1608, active in Italy); casting attributed to Pietro Tacca (Italian, 1577-1640)

Description:
A type of “nationality” field, though not in adjectival form; country refers to the modern name of the country (use ULAN’s nationality as a guide).  ARTstor Country data will not display with the record in ARTstor.  It is a functional field that, if populated, allows ARTstor users to filter search results by selecting values from the Geography list when performing advanced searches.

Guidelines:
This is a controlled field.  Select a term or terms from the list of countries below. These terms are identified, in TGN, as nations.

Examples:
Côte d'Ivoire
Kazakhstan
United Kingdom

	<xs:element name="Title">
		<xs:annotation>
			<xs:documentation>Required
Description:
Titles, identifying phrases, or names given to a work of art, architecture, or material culture.

Guidelines:
Use typical, American style, title case. Leading articles may be dropped. String phrases together for descriptive titles, using punctuation to separate phrases. For details, add “detail” at the end following a semi-colon after the main title. If necessary, describe the detail. If there are two titles, or a formal and informal title, or the title comes in two languages, you may put the preferable one first and put parentheses around the 2nd one. 

Examples:
Chartres Cathedral; west facade; central doorway
Landscape with Storm; detail of ducks in foreground
Déjeuner sur l’Herbe (Luncheon on the Grass)
Two Masks in Performance

Guidelines:
A free-text field that may include a range of years, a decade or a century. Use BCE and CE. Whereas BCE should always be used, CE need only be used with dates in the first couple of centuries where there might otherwise be confusion.

Examples:
1863

early 5th century BCE

Free-text field to capture any date information associated with the original “capture” of the image. This information is especially useful when an older photograph or drawing documents the state of a building or other monument at a particular time.

	<xs:element name="ARTstorEarliestDate" type="xs:int">
		<xs:annotation>
			<xs:documentation>Conditionally Required, Numeric value only
Description:
Year that broadly delimits the beginning of an implied date span.

Guidelines for both ARTstor Earliest Date and ARTstor Latest Date:
ARTstor Earliest Date and ARTstor Latest Date are functional fields intended for searching and sorting.  They will not be displayed in ARTstor. If populated, users will be able to filter search results by date range when creating an advanced search as well as sort results by date.  

Use numerals only and include full number (“1956, not “56”). For BCE dates, precede the number with a hyphen. (“-345”). Together with ARTstor Latest Date, this field creates a range that should reasonably characterize the most active span of time. Thus, it makes sense to avoid wide ranges simply to encompass an earlier structure that was destroyed or a late remodeling.

For BCE X00-X01: 3rd c. BCE has earliest date of  -300 and latest date of -201

For CE X00-X99:  5th c. CE has earliest date of 400 and latest date of 499
If you want to follow a “strict” rule, you can think of early, middle and late as having specific earliest and latest dates: 
early 15th century=”1400” and “1433”; 
mid 15th century=”1434” and “1466”; 
late 15th century=”1467” and “1499” 

For BCE dates: 
early 4th century BCE=”400” and “-367”; 
mid 4th century BCE=”-366” and “-334” and 
late 4th c. BCE=”-333” and “-301”

Examples:
109
1945
2007

	<xs:element name="Location">
		<xs:annotation>
			<xs:documentation>Description:
For monumental works and architecture, the name and geographic location of the work.

Guideline:
LC NAF will help a significant amount of the time for building names. “City, Country” is the standard format for identifying the location of structures. Use the English form provided in TGN (http://www.getty.edu/research/conducting_research/vocabularies/tgn/) for geographic terms. If cataloging architecture, and thus the building name is in Title, then include city and country. When cataloging frescoes and other site-specific works, be sure to include in Location the terms required to locate the work that do not appear in Title. This may require including building name, perhaps even the specific chapel, as well as the city and country. 

Examples:
San Francesco (Church: Assisi, Italy)
Paris, France
Cappella Brancacci (Santa Maria del Carmine (Church : Florence, Italy))

Note: local practice may vary from the strict LC NAF form cited in the examples above

Guidelines:
English and metric are both perfectly acceptable; no need to give both or convert from one to the other. If work is in more than one part, provide measurements for the parts if you have them. Spell out English units but use metric abbreviations.

			<xs:documentation>Description:
The name and geographic location of the repository that is currently responsible for the work

Guideline:
Use the authorized form (not the headings labeled “references”) found in the LCNAF: http://authorities.loc.gov/. Note that LC does not use a standard formulation for every authorized term. When the authorized form is “unfriendly” and, typically in a language unfamiliar to most native English speakers (in LC NAF the preferred term, for example, is “Gosudarstvennyĭ Ėrmitazh (Russia)”) look for the Used For/See From terms and select an alternative (“Hermitage Museum (Russia)”). Typically, the building, city, and country identifying the location of site-specific works such as frescoes are entered in the Location field. 

Examples: 
Staatliche Museen zu Berlin--Preussischer Kulturbesitz. Antikensammlung
Metropolitan Museum of Art (New York, N.Y.)
National Gallery of Art (U.S.)
National Gallery (Great Britain)

Note: local practice may vary from the strict LC NAF form cited in the examples above
