1 Introduction (informative)
This document includes terms intended to be used as a controlled value for Audiovisual Core terms ac:variant and ac:variantLiteral.
1.1 この文書の内容のステータス
Section 1 is informative (non-normative).
第2節は規範的な内容です。
Section 3 is informative (non-normative).
セクション 4 では、用語のIRI(Term IRI)、定義(Definition)、制御値(Controlled value)の値が規範的なものです。 使用法(Usage)の値がもし存在する場合、それは規範的なものです。 用語の名前(Term Name)の値は非規範的ですが、名前空間の略語の接頭辞はその用語の名前空間で一般的に使われるものであると予想できます。 Label and the values of all other properties are non-normative.
1.2 RFC 2119 キーワード
この文書における “MUST”、”MUST NOT”、”REQUIRED”、”SHALL”、”SHALL NOT”、”SHOULD”、”SHOULD NOT”、”RECOMMENDED”、”MAY”、”OPTIONAL” というキーワードは、ここに示されているようにすべて大文字で記載されている場合に限り、BCP 14、[RFC 2119] 、[RFC 8174] に記述されているように解釈されます。
2 用語の使い方
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:variant. Controlled value strings SHOULD be used as values of the property ac:variantLiteral.
2.2 Relationship between values of ac:variantLiteral and ac:variant
An IRI for a term in this vocabulary denotes the same concept as the concept denoted by the controlled value string for the same term. Thus a client MAY infer an IRI value for ac:variant given a controlled value string for ac:variantLiteral even if that IRI is not explicitly stated. The practical implication is that data aggregators MAY materialize values for the preferred ac:variant property in cases where providers only provide values for ac:variantLiteral.
