Overview
Meta-data is information set in files which describe the file. For example, title, artist, version, year etc. Most modern audio formats support some degree of meta-data.
Wagtail allows the setting of arbitrary meta-data through the use of the details file and matching commands specified in format.conf.
The meta-data fields used and their semantic meaning is completely up to the administrator of a Wagtail setup. However, this page details the fields considered by the default configuration files and the implied meaning. Note that the defaults supplied vary from version-to-version of Wagtail and you may need to update your configuration files to make use of these fields.
These fields refer to the details file names, in some cases the matching command in format.conf will use a different key when setting the meta-data in the file. For example, the command for disc-title writes into a field named "ALBUM" on FLAC and OGG/Vorbis files.
