The MusicBrainz XML Metadata Format (MMD) is an XML based document format to represent music metadata. The initial and predetermined use of MMD is in the MusicBrainz Web Service, and is determined by a Relax NG schema
JAXB can parse the schema and present it as packages classes making it easy to read and write from data matching the schema.
