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 late 2015, EIDR contains over 827K content assets (up 14% from 2014), including 143K movies, and 387K episodes of over 24K TV series. EIDR is an implementation of a Digital Object Identifier (DOI).
