Reference

schema:DefinedTerm

Definition

A word, name, acronym, phrase, etc. with a formal definition. Often used in the context of category or subject classification, glossaries or dictionaries, product or creative work types, etc. Use the name property for the term being defined, use termCode if the term has an alpha-numeric code allocated, use description to provide the definition of the term. Use the about property to specify what the term is about.

Scope

Parent class(es): Intangible (https://schema.org/Intangible).

CDIF

Definition

schema.org Defined Term schema.

**Union-type policy:** In CDIF profile UML models an attribute typed as schema:DefinedTerm is represented by a single attribute of that class type. The JSON Schema implementation permits the property value to be EITHER a plain string (interpreted as schema:name or schema:termCode in the default vocabulary) OR a full schema:DefinedTerm object (with explicit @type, name, identifier, termCode, inDefinedTermSet). Consumers should accept either form.

Note that this differs from the cdif Concept policy: a Concept (skos:Concept) in CDIF profiles MUST be a controlled-vocabulary entry (object form or @id-reference) — plain strings are not permitted for Concept-typed values because vocabulary identity cannot be recovered from an unscoped label.

Scope

schema:DefinedTerm - a term from a controlled vocabulary used as a value (keywords, additionalType, measurementTechnique, ...).

JSON serialization: In a JSON instance, a property typed as DefinedTerm may also be supplied as a plain string (the term's label) or as an object reference ({"@id": ...}) instead of a full schema:DefinedTerm object.

Attributes

Name	Type	Multiplicity	Description
identifier	Identifier	[0..1]	Documentation Original Reference schema:identifier Definition The identifier property represents any kind of identifier for any kind of [[Thing]], such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See [background notes](/docs/datamodel.html#identifierBg) for more details. Scope Domain: Thing (https://schema.org/Thing). Range: PropertyValue (https://schema.org/PropertyValue), Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition The primary identifier for the dataset; other identifiers should be listed in the sameAs field. Schema.org has three ways of encoding identifiers-- a text description, a URL, or by using the schema:PropertyValue field. The Science on Schema.org guidance strongly recommends using the PropertyValue approach. see https://github.com/ESIPFed/science-on-schema.org .... Dataset.md#identifier. Ideally, for any given data provided they would provide identifiers either all as strings or all as identifier_type. Scope @id / schema:identifier - URI for the term.
name	string	[1]	Documentation Original Reference schema:name Definition The name of the item. Scope Domain: Thing (https://schema.org/Thing). Range: Text (https://schema.org/Text). CDIF Definition text label for the term that is useful to human user Scope schema:name - the term's preferred label.
termCode	string	[0..1]	Documentation Original Reference schema:termCode Definition A code that identifies this [[DefinedTerm]] within a [[DefinedTermSet]]. Scope Domain: DefinedTerm (https://schema.org/DefinedTerm). Range: Text (https://schema.org/Text). CDIF Definition A representative code for this keyword in the controlled vocabulary. Analogous to skos:Notation Scope schema:termCode - code value within the term set.
inDefinedTermSet	XsdAnyUri	[0..1]	Documentation Original Reference schema:inDefinedTermSet Definition A [[DefinedTermSet]] that contains this term. Scope Domain: DefinedTerm (https://schema.org/DefinedTerm). Range: DefinedTermSet (https://schema.org/DefinedTermSet), URL (https://schema.org/URL). CDIF Definition Name for the controlled vocabulary responsible for this keyword. Scope schema:inDefinedTermSet - URI of the controlled vocabulary containing this term.
additionalType	XsdAnyUri	[0..*]	Documentation Original Reference schema:additionalType Definition An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org <a href="https://schema.org/docs/styleguide.html">style guide</a>. Scope Domain: Thing (https://schema.org/Thing). Range: Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition identifiers for datatypes from other vocabularies (not schema.org) that apply to this metadata. Scope schema:additionalType - additional type assertion for this term.
