Metadata

Metadata is data about data, such as a description of the contents of an audio file.  Good use of metadata improves our ability to discover resources, e.g. using OLAC Search.

Metadata uses controlled vocabularies, to support good precision and recall when searching for language resources, e.g.:

 Controlled Vocabulary Reference Examples
