OpenSubsonic API

The original Subsonic API reached its final version 1.16.1 many years ago and hasn't been maintained since. After that, numerous Subsonic-compatible clients and servers have been created as open source projects, while the original Subsonic server is closed source.

OpenSubsonic API is an open source initiative to create backward-compatible extensions for the original Subsonic API. It's supported by several servers and clients and being actively developed. The Subsonic server back-end in ownCloud Music app supports some of these extensions.
