Summer of Code: Acceptance and projected milestones

I’m pleased to announce that Google’s Summer of Code has announced which projects have been accepted. I’m pleased to let you know that our own Oliver Chalres and Lukáš Lalinský have been accepted to both work on our Next Generation Schema. Congratulations to both of you — this should be an exciting summer!

As the first act of getting ourselves organized for Summer of Code, the three of us have agreed to the following milestone schedule over the summer:

May 25: Object model and read-only user interface in place. This is essentially equivalent to Lukáš’ NGS-p implemented in Catalyst/Template Toolkit based on Oliver’s work from the last year. With this milestone users will be able to convert an existing database to the NGS schema and be able to browse the data in the new schema via the read-only user interface. No editing will be possible at this point in time.

June 29: The basic types are in place for editing artists, labels, and release-groups. Release and track level edits will not be complete.

July 27: Release and release related edit-types will be in place, but without a complete UI. The release edits will take a lot of work to get right so, we’ll have these edits in place, but may not be able to finish a working UI for them.

Aug 31: All remaining edit types are in place and the NGS enabled server enters a final beta phase.

Note that SoC doesn’t officially start until May 23 — we’re not wasting any time — in face our first milestone is due 2 days after SoC starts. Can you tell we’re serious this year?

Upcoming releases: Release groups and Next Generation Schema

In the past month there has been a ton of activity behind the scenes here at MusicBrainz and I can finally give a cohesive update on our plans for the next few months.

The much anticipated Release Groups release has been coded by Lukas in a weekend code sprint based on the old Mason codebase. Even though we had declared the old codebase as end-of-life, we have decided to push release groups out using the older code in order to satisfy the needs of the BBC and other customers. As part of this release, I will also add ISRC support and include a handful of bug fixes. Expect this release in May — I’ll post again when the date is firmly set.

And what is even more exciting is that we’re about to start work on our much anticipated Next Generation Schema (NGS). Discussed and planned over and over again, we’ve finally settled on an approach that appears to make everyone happy. As part of SoC, we’re likely going to accept Oliver and Lukas’ proposals to work on NGS over the summer. The goal is to implement all of the new schema in one release based on the TemplateToolkit/Catalyst work that Oliver has been working on since last summer. We’re going to take a step back and create a new object model/schema and then glue the TT UI onto the new object model.

The schedule puts the TT/Catalyst/NGS release into final beta test on August 31, with a release following in 15-30 days after that date. Please note, however, that there will be no other release based on Oliver’s TT work before NGS is release in September. We had to skip that release in order to pull in the schedule to make the target date of August 31.

I am quite excited by the work that is being done in the server area right now — we’re on our way to get past some significant hurdles. Just yesterday I got a first glimpse at the MusicBrainz site partially translated to Dutch — startling at first, but quite exciting when you think about it.

Many thanks to Matt Wood at the BBC for having the patience and dedication to work with MusicBrainz. Many thanks to Lukas for the coding sprint to get Release Groups off our collective plate. And of course many thanks to Oliver, Nikolai, Brian for your continuing hard work on TT. And thanks to everyone who has been supporting this team over the past few months.
