1 Introduction (informative)
This document includes terms intended to be used as a controlled value for Audiovisual Core terms
ac:subtypeLiteral. Note: Although this is a controlled vocabulary, the type of its terms is
rdfs:Class rather than
skos:Concept as in other controlled vocabularies because it indicates the type of the media item.
1.1 Status of the content of this document
Section 1 is informative (non-normative).
Section 2 is normative.
Section 3 is informative (non-normative).
In Section 4, the values of the
Controlled value are normative. The value of
Usage (if it exists for a given term) is normative. The values of
Term Name are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace.
Label and the values of all other properties are non-normative.
1.2 RFC 2119 key words
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.
2 Use of Terms
2.1 Relationship of value types to property terms
In accordance with the Audiovisual Core Term List document, unabbreviated term IRIs SHOULD be used as values of the property
ac:subtype. Controlled value strings SHOULD be used as values of the property
2.2 Relationship between values of ac:subtypeLiteral and ac:subtype
An IRI for a term in this vocabulary denotes the same class as the class denoted by the controlled value string for the same term. Thus a client MAY infer an IRI value for
ac:subtype given a controlled value string for
ac:subtypeLiteral even if that IRI is not explicitly stated. The practical implication is that data aggregators MAY materialize values for the preferred
ac:subtype property in cases where providers only provide values for
