New MetaBrainz site, new look and Live Data Feed access tokens

If you’ve been following this blog, you’ll be aware that we’ve been working on a complete overhaul of our branding and the look and feel of our web sites. While we still have a few minor adjustments to make here and there, we are happy to present you with our newly re-designed MetaBrainz Foundation web site.

MetaBrainz

New features of this site include our new site design, new logos, showcasing our projects and our customers, and HTTPS support. But the most important feature of this new site include online sign-up for commercial use of our data and access token generation for our Live Data Feed.

Two months ago we announced that as of today our Live Data Feed would require an access token in order to download the replication packets. These access tokens are available for free for private use and available on a sliding support scale for commercial use. Starting right now, you may go to the new Sign Up page and associate a new MetaBrainz account with your existing (or new) MusicBrainz account. Once you complete the sign-up process, you will be able to generate an access token to use with our Live Data Feed. We will post details on what to do with this access token after the schema change release takes place later today.

We’ve needed this new site for years and years, but have always been too busy focusing on our flagship project MusicBrainz. But, with help from Roman Tsukanov (aka Gentlecat) and MonkeyDo, we have finally released a web site that both brings us into modern times and streamlines the process for commercial users to start using our data.

If you are curious about what logos we chose for our other projects, see the animation on the MetaBrainz home page. Soon we will roll out the new site design onto CritiqueBrainz, BookBrainz, Cover Art Archive and our Picard site. However, since MusicBrainz is not built on the Bootstrap toolkit it will take us a while to roll the design out onto that site.

Thank you to Gentlecat, Nicolas at MonkeyDo, and everyone who gave feedback on the many logo and site designs that have been floated here for the past few weeks.

Announcing libmusicbrainz4 releases 4.0.1 and 5.0.0

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.

Announcing libmusicbrainz4 release 4.0.1

v4.0.1 of libmusicbrainz4 has now been released. This is primarily a maintenance release to fix a couple of bugs that were reported. Additionally, the code has now moved to GitHub, and can now be found at
https://github.com/metabrainz/libmusicbrainz.

The main changes are:

  • Fixed bug LMB-30 – Unable to access all relation lists on objects with multiple relation lists
  • Fixed bug LMB-31 – mb_relationlist_get_targettype always returns “target-type”

The interface has changed as regards to retrieving relation lists, due to LMB-30. Previously, the library only returned the last relation list that was returned in the XML response. The old ‘RelationList’ method on the Artist, Label, Recording, Release, ReleaseGroup and Work classes has been marked ‘deprecated’, and a new ‘RelationListList’ method will return a list of all relation lists for the entity.

For backwards compatibility, the ‘RelationList’ method will operate in the same manner as release 4.0.0, only returning the last relation list.

As ever, please see the enclosed README for details on support and bug reporting. The release is available for download at http://musicbrainz.org/doc/libmusicbrainz.

libmusicbrainz 4.0.0 released!

Andy Hawkins says:

In conjunction with Lukas I’ve been working on a complete rewrite of libmusicbrainz to support the new Web Service v2 released alongside NGS. I’m happy to announce the official release of this new library (libmusicbrainz4).

The library is written as a relatively simple parser for the results from the Web Service, with as little logic as possible. This should mean it is easy to maintain to keep in step with any changes in the schema for the XML Web Service.

The main interface is a C++ class ‘CQuery’, that returns a Metadata object containing a parsed version of the response. There is also a C interface that loosely wraps the C++ classes.

Using the library requires a good understanding of the queries and responses to and from the Web Service. Download the library, or browse the online documentation or generate the documentation from the source with make docs.

If you find any issues, please report them using JIRA (under the project ‘libmusicbrainz’).

I will follow the musicbrainz-devel mailing list and the #musicbrainz-devel IRC channel on freenode in order to answer questions if at all possible.

Thanks.

Andy

Beta 2 release of libmusicbrainz4

Andy Hawkins has continued to make great work on the 4th version of libmusicbrainz, and has just announced the second beta release. Andy writes:

I am pleased to announce the second Beta release of libmusicbrainz4, a client library for retrieving data from the MusicBrainz service using the latest /ws/2 web service.

This is a significant rewrite of the code since Beta 1, but this should mean it is much easier to maintain going forward. Unfortunately it is not ABI compatible with Beta 1, which will mean all client applications will need to be recompiled (and are likely to require some code changes).

The main changes are in the areas of list handling, with a cleaner internal implementation of lists. Additionally, the C interface is now generated automatically from an XML description file, and there is correct handling for some XML schema changes that have been made since the first release. Finally, the ownership of items in the C interface has changed slightly, please check the documentation for each method in the C interface for full details.

Note that some include files have been removed. I would recommend that you clean out the ‘include/musicbrainz4’ directory in your install location before installing this newer version.

The library is available to download here:

ftp://ftp.musicbrainz.org/pub/musicbrainz/libmusicbrainz-4.0.0beta2.tar.gz

Documentation is generated from the source (make docs), an online copy is available here:

http://users.musicbrainz.org/~luks/docs/libmusicbrainz4/

Please also check the sample programs (under ‘examples’) for details on how to use the library.

If you find any issues, please report them using JIRA (under the project ‘libmusicbrainz’) here:

http://tickets.musicbrainz.org/

As ever, please feel free to ask any questions about the library either here or via the #musicbrainz-devel channel on IRC (when I’m around).

Beta release of libmusicbrainz4 with NGS support

Andy Hawkins and Lukáš Lalinský have been doing some work on libmusicbrainz, and a beta release of version 4 is now available. Here’s what Andy has to say:

libmusicbrainz and libtunepimp test releases

On the excessively long road to the next stable Picard release I need to do a stable release of libmusicbrainz and libtunepimp. Both of those are now complete with all the bug fixes that I want to get into these before the next release. If you run Linux or Mac OS X, please take a moment to download, compile, test and install these two tarballs:

  1. libmusicbrainz-2.1.2-pre1.tar.gz (Changelog)
  2. libtunepimp-0.4.0-pre6.tar.gz (Changelog)

Please note that the independent python bindings for libmusicbrainz have been wrapped back into libmusicbrainz itself and can be found in the python directory of the tarball. libmusicbrainz has a new example program called getrels that shows how to retrieve AR links via the web service. libtunepimp has undergone major changes and now sports a plug in system that will make it easier to add more formats.

Unless these tarballs have major issues, I plan to update the version numbers to 2.1.2 and 0.4.0, respectively, and release them in the coming days. Then I’ll focus on getting stable release of Picard out the door.
