MusicBrainz web API
The REST-based webservice API for direct access to MusicBrainz data with output in XML and JSON (Please review the libraries above before writing your own implementation).
See also: MusicBrainz API/Examples
Search requests and Indexed Search Syntax
XML RelaxNG schema
Release Editor Seeding: Providing programmatic information to the release editor (from another site or an application), the closest we have to an edit API as yet
(internal) JS autocomplete API
Server setup
The MusicBrainz Server is not available as an executable application. Setting up the server will require you to checkout the source code and follow the INSTALL file's instructions.
The MusicBrainz Database contains all the metadata information available on and it's free for anyone to download and make use of it (and we encourage this!). Setting it up will require access to a PostgreSQL database. See instructions from server setup or use third-party [1].
Server environment variables that may prove useful
Search Server Setup and Search Indexer Setup if you're brave enough to want to try.
Embedded metadata
Picard Tag Mapping: The documentation for how Picard maps concepts to tags; useful if you want to use these tags elsewhere, or if you'd like to follow the same standard.

Communicating with other developers
IRC: Here's where you ask questions of real live people, if anyone's awake. You love it, you know it.
Forum: And here's where you ask if we aren't awake, or for anything style-related or needing more consideration than can be easily given in IRC.
MusicBrainz Summits: These happen occasionally, and people get together and talk about MusicBrainz. You should consider coming! Even if not, the discussions had here are sometimes important, and might be worth perusing.
