Amplifind, the company that operates the MusicDNS/PUID service, recently sold its intellectual property and the PUID service will be going away eventually. It is exactly this reason why we’ve been uncomfortable relying on closed source fingerprinting software to make MusicBrainz tick.
Fortunately, I’m pleased to announce that the open source fingerprint era has begun!
Lukáš Lalinský has been working on acoustid for months now and today the EchoNest, in conjunction with 7Digital and MusicBrainz, has issued a press release that announces Echoprint, their fully open source fingerprinting solution.
We’re pleased to announce preliminary support for Echoprint in MusicBrainz on our echoprint test server. The Echoprint system works similarly to how PUIDs work in MusicBrainz right now. You can use echoprints anywhere you can use PUIDs on the Echoprint test server. The version 2 of our XML web service (on the echoprint test server) now supports submitting and fetching Echoprints. To submit an Echoprint, refer to our web service documentation and example page and use echoprint wherever you’d use puid. For instance, to submit an Echoprint to the test server, POST an XML document like the one below to the /ws/2/recording resource:
<metadata xmlns="http://musicbrainz.org/ns/mmd-2.0#"> <recording-list> <recording id="e97f805a-ab48-4c52-855e-07049142113d"> <echoprint-list> <echoprint id="TRN5NGX1187AB4F786"/> <echoprint-list> <recording> <recording-list> <metadata>
Although it remains to be seen when the Echoprint system will be mature enough for inclusion on the live MusicBrainz servers, going forward MusicBrainz will only support fully open source fingerprint solutions, starting with Echoprint and acoustid. We are saying no to more closed source solutions, which have never worked out well for us. MusicDNS/PUID is now officially end of life and should not be used anymore in new development.
We look forward to working with the EchoNest closely to finish up the development of the Echoprint system and to fully integrate it into MusicBrainz when it matures.
