Abstract

Audiovisual Core uses the terms ac:variant and ac:variantLiteral to provide information about the size, extent, and availability of the Service Access Point of a media item. This controlled vocabulary provides values for those terms.

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 本文件內容的現況

Section 1 is informative (non-normative).

第 2 節為規範性。

Section 3 is informative (non-normative).

在第 4 節中，Term IRI、Definition和Controlled value的值為規範性。 Usage的值 (如果它存在於特定術語中) 為規範性。 Term Name的值為非規範性，不過可以預期命名空間縮寫是術語命名空間的常用前綴。 Label and the values of all other properties are non-normative.

1.2 RFC 2119 關鍵字

關鍵字「必須」、「不得」、「要求」、「應」、「不應」、「應當」、「不應當」、「建議」、「可」、「可選」的定義，請參照BCP 14 [RFC 2119] 及 [RFC 8174] 所定義之含義，惟詞彙須以全大寫形式呈現時方適用。

2 使用條款

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.
