Required Vocabulary Terms

Table of Contents

Introduction

These terms are required to be used in order to facilitate even the most basic understanding of the data. If a term is listed here then you MUST NOT use a different term for the same concept, as systems are expecting these terms. This is not to say that you MUST always have the terms in every record, you might not know (for example) the shape of an object, but if you do know it, then you must use the agreed upon URI for the concept of "shape".

Summary

For brevity in the table, the AAT URI is compacted with a namespace, however the full URI MUST be used in the data. For example, the URI for Primary Name is http://vocab.getty.edu/aat/300404670

Name Types

There are four required vocabulary entries for Names and Identifiers to be able to distinguish them from others. Each has particular requirements for use by the client or search system.

Primary Name

The URI for Primary Name is: http://vocab.getty.edu/aat/300404670

The main or primary name of the entity. Every record must have a name with the primary name classification so that user interfaces know which name to use. There may be multiple primary names for a single record, but each must have a unique language, or no language. See the name documentation.

Display Name

The URI for Display Name is: http://vocab.getty.edu/aat/300404669

A name to use when displaying the node which has the associated name. For Statements, this is typically used by interfaces as the label for the statement. For TimeSpans or other structured data, it is used in place of the structured data.

Sort Name

The URI for Sort Name is: http://vocab.getty.edu/aat/300451544

A name to use when sorting the entity along with other entities in a list. This classification can be used on the same name as the primary name, or on a different form of the entity's name. Different languages can have different sort names, however each language must not have more than one.

Sort Value

The URI for Sort Name is: http://vocab.getty.edu/aat/300456575

A non-linguistic identifier to use for sorting the entity along with other entities in a list, instead of a linguistic form as described above. There must not be more than one sort value per entity. User interfaces should not render the sort value to the end user.

Classification Types

There are six classifications that stand as categories when it is otherwise difficult to distinguish between very similar constructs in the same property. These are described in the types of types section, and sometimes referred to as "meta-types". A related required term is that for color, however it classifies a Dimension rather than another Type.

Statement

The URI for the Statement type is: http://vocab.getty.edu/aat/300418049

There are many types of Statements, and it is impossible to enumerate all of those different types in a way that could be implemented successfully and usably. Instead, the type of the statement (e.g. materials statement) is given a meta-type of "brief text" so that they can be recognized as the type of statement.

Type of Work

The URI for Type of Work is: http://vocab.getty.edu/aat/300435443

There are many types of works (painting, statue, print, ...) and it is equally impossible for any system to know all of them a priori. Instead the type of work of an object is classified with the Type of Work meta-type so it can be recognized.

Style

The URI for Style is: http://vocab.getty.edu/aat/300015646

Similarly, there are many styles and we use aat:300015646 to distinguish a style concept from other categorizations of the work.

Shape

The URI for Shape is: http://vocab.getty.edu/aat/300056273

There are, similarly, many shapes and we need to distinguish shape from other classifications.

Nationality

The URI for Nationality is: http://vocab.getty.edu/aat/300379842

In the same way as for objects and works, people also have a variety of types of classification associated with them. A common one is nationality.

People can also be categorized by their occupation.

Color

The URI for Color is: http://vocab.getty.edu/aat/300080438

As colors can be measured precisely as well as being treated as a category, the classification sits on the Dimension. The dimension might end up not having a value and unit, only a second classification for what sort of color it is (in this case, brown), but the required terminology is to use aat:300080438 on the Dimension.

Activity Types

There are several classifications for Activity that are important to use, as they they define core cultural heritage organization practices.

Exhibition Activity

The URI for Exhibition is: http://vocab.getty.edu/aat/300054766

Exhibitions are documented in their own section, but do not have a class of their own in the ontology. As such we need to give them a required classification so they can be recognized.

Provenance Activity

The URI for Provenance entries is: http://vocab.getty.edu/aat/300055863

Provenance activities also have their own section of the documentation, and do not have a class in the ontology. This classification is for the top level activity which groups together the other parts.

Publication Activity

The URI for Publication activities is: http://vocab.getty.edu/aat/300054686

Works, especially texts such as books, are published in an activity. These activities are embedded in the record for the work, but are no less important to be able to distinguish.

Promise Activity

The URI for Promises is: http://vocab.getty.edu/aat/300435599

Albeit a small part of the detailed provenance, there isn't a class for promises in the ontology, and thus we have to require terminology to fill the role.

Object/Item Flags

There are two flags that are useful to distinguish broad categories of items.

Collection Item

The URI for Collection Items is: http://vocab.getty.edu/aat/300404024

It is useful to be able to distinguish between records that describe items in the "collection" of an institution from records that describe other physical or digital objects or intellectual works. Equally there are things which are part of the collection but one might not describe as artworks, as below, such as archival material or reference collections.

{
  "@context": "https://linked.art/ns/v1/linked-art.json",
  "id": "https://linked.art/example/object/nightwatch/49",
  "type": "HumanMadeObject",
  "_label": "Night Watch by Rembrandt",
  "classified_as": [
    {
      "id": "http://vocab.getty.edu/aat/300404024",
      "type": "Type",
      "_label": "Collection Item"
    }
  ]
}

Artwork

A second important distinction is between objects that are artworks and objects that are not. There might be two chairs in a gallery -- one is art, and the other is just a chair for visitors to sit on.

  "type": "HumanMadeObject",

}
