EIDR, or the Entertainment Identifier Registry, is a global unique identifier system for a broad array of audio visual objects, including motion pictures, television, and radio programs. The identification system resolves an identifier to a metadata record that is associated with top-level titles, edits, DVDs, encodings, clips, and mash-ups. EIDR also provides identifiers for Video Service providers, such as broadcast and cable networks. As of the end of 2014, EIDR contains over 723K content assets (up 24% from 2013), including 130K movies, and 346K episodes of nearly 15K TV series. EIDR is an implementation of a Digital Object Identifier (DOI). ==History== Media asset identification systems have existed for decades. The common motivation for their creation is to enable the management of media assets through the assignment of a unique id to a set of metadata representing salient characteristics of each asset. Over time such systems tend to proliferate, with each arising to deal with a specific set of issues. As a result there is considerable variation between systems in terms of which assets are categorized, which metadata is associated with each asset, and the very definition of an asset. To name a few examples, should a “director’s cut” of a movie be distinct from the original theatrical release? How should regional variations (e.g. translation of the title or dialog into foreign languages) be accounted for? Further complications include the procedures (and required credentials) for adding new assets, editing existing assets, and creating derivative assets. EIDR was created to address these issues, as well as others encountered in video asset workflows, both in a B2B context as well as intramural post-production activities internal to a content producer. EIDR has the following characteristics: *A central registry available to all participants *Ability to easily register new assets *An asset ID that is immutable (and in particular with respect to changes in asset ownership or location of the metadata or the asset itself) *Detection/prevention of duplicates of the same asset being created *Ability to create a set of video assets derived from an abstract work (e.g. original theatrical release, director’s cut, language-variants) *Ability to group video assets by more general relationships (e.g. episodes of a season of a TV series) *A core set of metadata to differentiate assets, even when closely related *Scalable, immutable, persistent EIDR is intended to supplement —not replace— existing asset identification systems. To the contrary, a key feature is to allow an EIDR record to include references to that asset’s ID under other systems. This feature is particularly useful for film and television archives, making it easy for them to cross-reference their holdings with other sources for the work and metadata about it. By design, EIDR does not replicate features of other asset ID systems, e.g. commercial systems that seek to add value through enhanced metadata (e.g. plot summaries, production details). It is also a non-goal to track ownership and rights information, which can, however, be implemented as applications that use the EIDR ID. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EIDR」の詳細全文を読む スポンサード リンク
