A couple of weeks ago (Oct. 30th through Nov. 1st), the MusicBrainz Summit 15 took place in Barcelona, at Rob “ruaok”‘s place. We had all of the MetaBrainz employees there, Rob/ruaok (local), Michael/bitmap (US), Nicolás/reosarevok (Spain/Estonia), Roman/Gentlecat (recently local), Laurent/zas (France), and myself, Freso (Denmark) – in addition to a bunch of other people from the community: Sean/Leftmost (US) and Ben/LordSputnik (UK), the two lead developers of BookBrainz; chirlu (Germany), long-time volunteer developer on MusicBrainz; and Alastair/alastairp (local), lead of AcousticBrainz. Between us, we represented 7 countries, 8 nationalities, and 9 languages.
We managed to cover a lot of ground on the serious topics, discussing how to avoid data/MBID loss and how to version data, how to deal with labels (the entities, not the corporations…) and other unresolved style issues, how to integrate all the various *Brainz projects more and better, and a bunch of other things. The official notes for the summit is stored in a public Google Docs document. Feel free to read through and it jot down your own comments!
One of the big things was the we decided again-again-again (for the third or fourth year in a row?) to release the translations of MusicBrainz.org. But this time we actually did it! So MusicBrainz.org is now available in German, Dutch, and French (in addition to English) – go check that out if you have not done so already. 😉 At some point in the not-too-distant future™ we will also enable translating all of our documentation. Sean/Leftmost volunteered to look into options for this. Expect to hear more on that later!
We had some talk about how and why MBIDs get lost and what we can do to prevent this. As part of this discussion, we decided to make more edits autoedits for everybody. This was partly due to a wish of having a shorter queue of open edits (and there’s been a significant drop in open edits since Nov. 16!), but also very much to avoid losing MBIDs once they have been generated. More in depth discussion of the reasoning (and some of the community’s response) can be seen in the server release blog post and its comments.
We talked about a few other things like genres, reviewing the work of the style BDFL and the community manager, the future direction of the MetaBrainz Foundation, and a couple of other topics. The summit notes should contain more information on what we talked about and decided on these points.
Obviously it was not all talk and talk and talk. There was also plenty(!!) of chocolate. yeeeargh helped us by getting a lot of Ritter Sport as he apparently lives right next to their factory, and sending it along with chirlu to Barcelona. Thank you, yeeeargh!

Finally, a big thank you to Google and Spotify for helping to fund this meeting. It would have been a lot harder to bring all these people together from around the world without their (continued, no less!) support. Here’s to 2016 and summit 16!
