Schema change server update, 2012-05-15

May 15th, 2012

Nearly one year after we released NGS, we have another schema change update with lots of new features!

This release contains 9 new features and improvements that take advantage of the new schema. These are:

  • More social user profiles which can now have Gravatars, languages (and the users proficiency) age and country.
  • More expressive aliases for artists, labels and works. Aliases can now have types, sort names and multiple aliases may be used per a locale, along with the ability to mark one alias as ‘primary’ for that locale.
  • Release group types have been separated into primary and secondary types. A release group now has 1 primary type and may have multiple secondary types. This allows us to have ‘remix compilation albums’, for example
  • Works may have multiple ISWCs
  • Artists, labels and relationships may be marked as ‘ended’ to indicate that they have ended, but the exact date is not known
  • Vinyl style/free text track numbers are now supported.
  • Works may have a lyrics language associated with them
  • Artists and labels may have multiple IPIs
  • We have moved to use ISO 639-3 for our language table. While not all languages are exposed at the moment, this gives us a lot more flexibility going forward.

Many thanks to nikki for going way beyond our expectations for testing (and patience!); to Ian McEwan for his continued work on statistics; and to the MusicBrainz team for making this all happen.

If you have a replicated instance of MusicBrainz, please follow these instructions to get your server running on the new schema:

  1. Take down the web server running MusicBrainz, if you’re running a web server.
  2. Turn off cron jobs if you are automatically updating the database via cron jobs.
  3. Make sure your REPLICATION_TYPE setting is RT_SLAVE
  4. Switch to the new code with git fetch origin followed by git checkout v-2012-05-15-schema-change
  5. Run carton install --deployment. If you have not switched your installation to using carton, please read INSTALL.md on how to do this.
  6. Run carton exec -- ./upgrade.sh from the top of the source directory.
  7. Set DB_SCHEMA_SEQUENCE to 15 in lib/DBDefs.pm
  8. Turn cron jobs back on, if needed.
  9. Restart the MusicBrainz web server, if needed.

If you are running a mbslave mirror, check out the latest code and read the upgrade instructions in the README file.

Bug

  • [MBS-3189] – Remove unused ref_count column and related functions
  • [MBS-4616] – Add work language statistics
  • [MBS-4629] – /cover-art page shows no collections
  • [MBS-4637] – Timeline graph won’t graph anything without an entry in statistics/view.js
  • [MBS-4640] – Clicking cover art opens box with "����" (4 U+FFFD)
  • [MBS-4642] – Thickbox CSS interferes with MB CSS
  • [MBS-4647] – Cover art page allows submitting edit with no cover art when JS is off
  • [MBS-4648] – Changing cover art type from "other" to unset causes Internal Server Error
  • [MBS-4678] – upgrade.sh is not ready for testing
  • [MBS-4679] – Internal server error adding secondary types to a release

Improvement

  • [MBS-1485] – Alias types
  • [MBS-1798] – Lyrics language for works
  • [MBS-1799] – Add ISO 639-3 language codes to the database
  • [MBS-1981] – Add blog feed to the home page
  • [MBS-2240] – Aliases: certain locale can be used only once in the list of aliases
  • [MBS-2532] – Allow more than one IPI per artist
  • [MBS-2851] – Timeline graph events should be in the database
  • [MBS-2885] – Allow more than one ISWC per work
  • [MBS-3646] – Split release group attributes into two types
  • [MBS-3788] – Alias improvements
  • [MBS-4625] – Improve wording of cover art tab when cover art comes from relationships
  • [MBS-4676] – Do not allow people entering deprecated relationships

Announcing libmusicbrainz4 releases 4.0.1 and 5.0.0

May 15th, 2012

Andy Hawkins says:

Hi,

I am pleased to announce two new versions of libmusicbrainz:

libmusicbrainz-4.0.2 has been updated to take account of changes made to the server on 15th May 2012. Some interfaces are now marked as deprecated, as they have been extended during the work.

Full documentation is available here:

http://metabrainz.github.com/libmusicbrainz/4.0.2/

The release can be downloaded here:

https://github.com/downloads/metabrainz/libmusicbrainz/libmusicbrainz-4.0.2.tar.gz

(MD5 checksum 5ff62abeca00fdad1bb3a8f99065ae61)

libmusicbrainz-5.0.0 has been introduced to enable the library to be more easily included in Debian due to a conflicting package name. It is identical to libmusicbrainz-4.0.2, with the following exceptions:

1. All include files are now in the musicbrainz5 directory

2. You should now link against libmusicbrainz5 (-lmusicbrainz5)

3. All previously deprecated functions have been removed.

Please note that all future work is likely to only occur on the 5.x library, so this should be used wherever possible.

Full documentation is available here:

http://metabrainz.github.com/libmusicbrainz/5.0.0/

The release can be downloaded here:

https://github.com/downloads/metabrainz/libmusicbrainz/libmusicbrainz-5.0.0.tar.gz

(MD5 checksum 3396e0c66cfacfa1f32abc7cfdbcbe13)

As ever, please report any issues in JIRA at

http://tickets.musicbrainz.org

under the project ‘libmusicbrainz’.

If you have any questions, please post them in the musicbrainz-devel mailing list. I will also attempt to be available on the #musicbrainz-devel IRC channel on Freenode.

Search server index updating paused

May 15th, 2012

Tomorrow’s release requires us to update the main server and the search servers at the same time. This presents a bit of a chicken-and-the-egg problem: We need to build new indexes even before we’ve migrated the database to our new schema.

To accomplish this, I’ve stopped index updating and created a separate database that will allow me to build some indexes that will be a few hours out of date when we release tomorrow. They will be slightly old, but at least we will have indexes that work.

I expect the indexes to be up to date about 3 hours of the release is complete. If you find the indexed search out of date, please use the direct search in the meantime.

Sorry for any inconveniences this may cause.

Universal Music UK launches the Artist Gateway… using MusicBrainz!

May 9th, 2012

Universal Music in the UK just launched their Artist Gateway, a site to showcase their artists and to provide lots of detail about their artists. Universal is using MusicBrainz IDs and data throughout their system to give their site the proper structure and links to elsewhere on the net. To launch it, Universal put out a slick video, complete with a plug for MusicBrainz:

This is a huge step for MusicBrainz — in the past the labels didn’t even acknowledge our existence and now they are using our data.

Thanks James Cowdery & crew over at Universal in London!

Upgrading our data licenses

May 3rd, 2012

A potential customer just nudged me about our use of now deprecated CC licenses and a deprecated Public Domain dedication. We should really address these issues and upgrade our data licenses. We are currently using the following licenses:

I propose that we move to:

The move to the CC license version 3 allows us to use the latest and most robust version of the Creative Commons license. If you’d like lots more detail on what this change means, please read the CC version 3 license “brief” explanation.

The CC0 grant improves a number of aspects of our old Public Domain dedication, especially in jurisdictions outside the US. Our current dedication isn’t sufficient to renounce any copyright over the data in some countries. The CC0 grant is an improved version that maximizes the global coverage of our rejection of copyright for our data.

Summary in plain english: We’d like to move to updated, more robust licenses. We are not changing what data is available under which license, nor are we taking away any rights that end users already have.

If you have questions or comments, please post them here. If there are no objections to this change, I will make it effective with our May 15th release.

UPDATE: Fixed an incorrect link that Mike from the Creative Commons pointed out. Thanks Mike!

As a reminder, here are the tickets that will change our schema and here are all the tickets scheduled for the 15th.

Looking for Language Liaisons

May 1st, 2012

As some of you may know, this summer through Google Summer of Code I’m working on internationalization of musicbrainz-server. As outlined in my proposal, I’m currently looking to find what I call “language liaisons”: folks willing to be the go-to person about a given language for me and other developers.

Auf deutsch!

Auf Deutsch!

What’s expected of liaisons:

  1. Willing to be pestered occasionally, by me or other developers, about language-specific concerns: when adding new features, and thus adding new strings, we’d like to be able to ensure nothing’s added that will need to be changed before it can be translated into a given language.
  2. Willing to file bugs for strings already in the database that are untranslatable, should you find them.
  3. Be on the musicbrainz-i18n mailing list; this will be the main venue for organization and communication about i18n issues.
  4. Ideally, to be an active translator for your language – but this isn’t a requirement, because I’d like to get the widest global coverage I can; even if a language doesn’t currently have a translation, we don’t want to unintentionally sabotage future translators with untranslatable strings!
musicbrainz-japanese

日本語

I’ll also be determining a (related) list of “target languages” for the summer, with the intention of releasing translation on musicbrainz.org with these languages at the end of the summer. I’ll consider for inclusion on this list languages that are both in active translation on Transifex and have language liaisons.

If you’re interested in being a language liaison, please contact me: ianmcorvidae (at) musicbrainz (dot) org, editor ianmcorvidae, or ianmcorvidae on IRC, and join the mailing list.

If you’re interested in i18n generally,  please join the musicbrainz-i18n list. For more information on my project and musicbrainz-server i18n, see the server internationalization wiki page, my post on my personal blog, and my official proposal, or come ask about it on IRC or the mailing list!
