Welcome Silona Bonewald, new MetaBrainz Foundation Executive Director!

We are very pleased to announce that the MetaBrainz Foundation has appointed Silona Bonewald as Executive Director, following the unfortunate passing of our Rob at the beginning of the year.

Silona has served as Executive Director of IEEE SA Open and Vice President of Community Architecture at Hyperledger, part of the Linux Foundation. Earlier in her career she served as Director of InnerSource at PayPal and authored the widely used O’Reilly publication Understanding the InnerSource Checklist.

Silona also founded the League of Technical Voters, a 501(c)(3) organization dedicated to government transparency through open source technology, and has since advised nonprofit and open source organizations including the Cardano community’s IntersectMBO, the Foundation for Public Code, and the Software Freedom Conservancy. She has served on the board of the Electronic Frontier Foundation’s Austin chapter in the past and holds standing relationships across the world wide standards communities, and more… If you would like to keep browsing Silona’s looong list of professional credentials you are welcome to follow her on LinkedIn.

That’s all a long way to say that we are very excited to have Silona on board! The team is looking forward to working with Silona and you (our wonderful community) to carry Rob’s legacy forward.

Please give Silona a warm welcome in the comments!

Silona will also be hosting an AMA on 5 October 2026, at 17:00 UTC, on the forums (we will do another announcement regarding this, closer to the time), where you can post questions and share with Silona some of your dreams for the future of the MetaBrainz Foundation and its projects!

GSoC 2026: Bringing Internationalization (i18n) to BookBrainz

Introduction

Greetings, everyone!

I am Garv Thakre (@garvthakre:matrix.org on Matrix), an Agentic-AI FullStack Developer . This summer, I had the opportunity to participate in Google Summer of Code 2026 with MetaBrainz, where I worked on the internationalization (i18n) for BookBrainz.

I was mentored by Nicolas Pelletier (@monkey:chatbrainz.org on Matrix). This post summarizes my project, its outcomes, and my experience over the course of the program.

Project Overview

BookBrainz aims to collect information about every book ever written, but until now, the interface was only in English. Since books exist in thousands of languages, having an English-only UI made it tough for non-English contributors to navigate, read, or add metadata.

My main goal this summer was to get BookBrainz ready for translation and set up the foundation so the community can actually start localizing it. Here is what that involved:

MerchBrainz

We have added a range of great new MetaBrainz designs to our merch store: https://www.redbubble.com/people/metabrainz/shop

These designs by Monkey, previously only available to MetaBrainz summit attendees, have been lightly modified (summit-specific text removed) for everyday wear. Are many people going to know what you’re repping? No. Are the ones that do going to go “DAAAAAAAAAAAAMN IT’S THE BRAINZ YO”? Most definitely!

GSoC 2024: Integrating imports into BookBrainz

It really bugged me that it proved impossible to finish the huge BookBrainz importer project last year. Fortunately MetaBrainz (and Google) gave me the chance to continue working on my 2023 project during this Summer of Code, thank you! Our goal is still to import huge external datasets into the BookBrainz database schema.

Last year I worked on the backend services to transform and insert simple entities into the database. This year’s goal was to support importing multiple related entities and exposing the imported data on the website. We can now import entities (on the backend), which can be reviewed and approved by our users with ease.

If you want to know the full story, I recommend you to start with my previous blog post to learn more details about the existing importer infrastructure and last year’s problems. Or just read on if you are only interested in the advanced stuff which I did this year.

MetaBrainz Summit 2024

This year it was New Delhi, India, that was invaded by data nerds from across the globe!

The MetaBrainz team was treated to the glorious chaos, hospitality, sights, noise, sweets, monkeys, traffic, heat, and delicious food of India. We reflected on the last year in MetaBrainz, planned and collaborated for the future, and got a little work done – when we could fit it in between mouthfuls of Indian sweets.

Read on for a comprehensive summit recap, including the annual recap for each MetaBrainz project, as well as breakout session notes, photos, and links to the slides and video recordings.

You are invited to MetaBrainz Summit 24

MetaBrainz Summit 24 is upon us! September 23-27 in New Delhi, India.

We would love for you to join us remotely. If you are reading this, you are qualified to attend. Congratulations! Read on for more information.

Downtime today for PostgreSQL / MusicBrainz schema change upgrade: 17:00 UTC (10am PT, 1pm ET, 7pm CEST)

Today (Monday, May 13) at 17:00 UTC (10am PT, 1pm ET, 7:00pm CEST), we’ll be:

Upgrading our production database server to PostgreSQL v16.
Performing the MusicBrainz schema change upgrade.

See the previous announcement on this topic for more information.

Expect MusicBrainz and services that depend on its database (MetaBrainz, ListenBrainz, the Cover Art Archive, CritiqueBrainz, BookBrainz) to be down for the hour, but we’ll be working to restore services as quickly as possible.

Afterward, we’ll post instructions here on how to upgrade your MusicBrainz mirror server (whether using musicbrainz-docker or otherwise).

P.S. The initially announced upgrades for MusicBrainz search engine are just about to reach our beta website, and thus are postponed for mirrors too.

Welcome Summer of Code 2024 contributors!

We are thrilled to announce the selection of 8 contributors to work with us for this year’s Google Summer of Code program!

MetaBrainz received many great applications this year. Selecting the final contributors was tough and involved deliberating various factors – what these contributors did right is getting in early, engaging with our community, presenting specific and detailed proposals, and proving excellent communication skills and the ability to integrate our feedback back into their proposals.

Thank you to all contributors who submitted a proposal with us!

MetaBrainz Summit 2023

As always, the silliest photo is the best photo. Left to right: aerozol, zas, outsidecontext, mayhem, yvanzo, bitmap, monkey, kellnerd, akshaaatt, reosarevok, laptop: atj, lucifer

A year has flown by and once again the MetaBrainz team found itself in the MetaBrainz HQ in Barcelona, Spain, for #summit23. And once again we were munching on a mountain of international chocolates, hiking Mt Montserrat, bird-watching, groaning at terrible puns, testing out mayhem’s Bartendro cocktail robot (some of the team committing themselves too thoroughly to this testing), and of course discussing everything and anything MetaBrainz related. This year we had a longer summit, taking place over the week instead of the usual weekend, broken up into three days of presentations, followed by two days of hands-on ‘hacking’.

This means it’s time to strap in for a long post!

Welcome Ansh Goyal to the MetaBrainz team!

I’m pleased to announce that we’ve added yet another former Summer of Code student/mentor to our team: Ansh Goyal. Welcome to our team, Ansh!

After Alastair Porter decided to not resume his position with MetaBrainz after his 6-month break, we were lucky to have Ansh ready to jump in to join our team. Thank you for your hard work over the years, Alastair!

Ansh will be focusing on Javascript programming, in particular React, on the BookBrainz and ListenBrainz projects. Both of these projects desperately need a lot of UI/UX work, and Ansh has proven himself that he’ll be able to help us tackle our backlog of UI projects that we need to accomplish in the short term.

Welcome to the team Ansh — we’re looking forward to your contributions!
