Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain extended plays as a release format, relay history, definitions and chart rules from music industry sources, describe the kinds the registry aliases name, and distinguish EPs from singles, albums, mini-albums and the audio storage medium itself.

A music release longer than a single but shorter than an album, typically containing three to six tracks and under about 30 minutes, originally a 7-inch vinyl format introduced in the 1950s, in forms such as reissues, split EPs shared by two or more artists, live EPs, remix EPs, collaborative EPs and promotional EPs; chart rules define EPs differently across countries.

What it is for: Releasing a short collection of tracks.

It can be explain the format; relay history and chart rules; describe kinds; distinguish related releases.

What the second pass must settle

  • Should split EP be a separate primary entry?
  • How should music industry sources be linked?
  • The registry parent audio storage device appears misfiled; should it be reviewed?
