Announcing the Cover Art Archive

October 9th, 2012

In a server update last April we quietly said that “we’ve also improved cover art support slightly.” What we actually did was release the first version of the Cover Art Archive, a cooperation between MusicBrainz and the Internet Archive. First, a little background:

Cover art (the images associated with music products) adds a great amount of value to the digital music experience. Many projects and apps on the net use these images to add color and depth to their music tools. However, there isn’t a cleanly organized, publicly available resource where everyone can access these images. You can use Amazon product images, but your project needs to be able to abide by their Terms of Service, which doesn’t work for everyone. Many projects use Google Images to source their cover art, but that is an inexact science since they may not always find the right image.

Furthermore, the copyrights around cover art have never been aggregated by anyone. Most of the copyrights for these images are not held by the labels that licensed the music itself. In a lot of cases, the actual copyright owner may not actually be known. All of this creates a lot of inequality around cover art and we hope to fix this inequality by curating a collection of clean and easily accessible images.

The Cover Art Archive aims to solve these problems. All images in the Cover Art Archive are indexed by the release’s MBID, and all metadata can be parsed by a JSON document. For instance, to fetch the front cover for any given release, construct this URL:

http://coverartarchive.org/release/76df3287-6cda-33eb-8e9a-044b5e15ffdd/front

Once you GET this resource, you will be redirected to the proper Internet Archive URL that yields either an image file or a 404 error if we do not have this image. For lots more details on how to use the Cover Art Archive, please take a look at our API documentation. So far, there are Java, C and Perl bindings to the API.

For some stunning examples of what people have already done with the Cover Art Archive, please take a look at these links:

So far, we’ve collected nearly 100,000 images that are attached to 54,000 releases for a 5% coverage in MusicBrainz. The largest file we have clocks in at 23MB and the largest image is 16,000 x 7842 (125 megapixels!). For all of the juicy stats on this project, check out our cover art statistics page.

We’ve just gotten started and we need your help! Won’t you please consider uploading some images to this archive? To get started, log in with your MusicBrainz account (or create a new one) find your favorite release and then click on the cover art tab to view the existing pieces of art and/or upload new ones. For more details, see our How to add cover art guide.

Thank you to everyone who has worked hard to make this project a reality! And thank you to Brewster Kahle and the Internet Archive for fostering this project!

Server update, 2012-10-01

October 1st, 2012

We’ve just finished pushing out an update today, which will be the last update before the schema change, which is now due in 2 weeks. Sadly, this release doesn’t feature the much anticipated relationship editor, which had to be reverted at the last minute as we still think it could do with more user testing. Hopefully it will make the next release!

This release features work from Aurélien Mino, Nicolás Tamargo, nikki, patate12, Pavan Chander, Ulrich Klauer and the MusicBrainz developers. Thanks for your work everyone!

Bug

  • [MBS-3825] – Release Editor is not displaying the release title on the tracklist tab

  • [MBS-5250] – Non-specific dates create negative ages
  • [MBS-5264] – Track Parser results in edits changing durations on tracks in mediums with discids in some cases
  • [MBS-5295] – Webservice should distinguish between "" and NULL as a value for release->barcode.

Help us make some stickers!

September 25th, 2012

MusicBrainz will be attending the Google Summer of Code mentor summit, and we’d love to have some stickers to hand out, so our fellow open-source friends can show off how cool we are. Sadly, we don’t have the skills to actually make the designs to send off to get printed… but that’s where you come in!

Do you do graphic design? Do you know someone who would be willing to help us? If so, please get in touch with us – leave a comment, tweet us or shoot an email to info@musicbrainz.org. Thanks!

Due to a conflict with Music Hack Day London, we’ve moved our summit to 9-11 November. We’re still meeting in Barcelona and are still planing the same event, just one week earlier.

For more details as they develop, please see our summit wiki page.

Splunk supports MusicBrainz!

September 19th, 2012

As part of Google’s Summer of Code program we accepted Dániel Bali to work on analyzing our web server logs to mine them for interesting information about MusicBrainz and people who are using MusicBrainz. (see a preview of this project)

To make that project a reality we had help from Splunk, the company that creates the fantastic data analysis tool by the same name. Splunk provided us with enterprise trial licenses during the summer and now going forward has accepted us into their Splunk for Good program. This program provides a free 10GB/day (it allows us to import 10GB of data into our Splunk server per day) license on a yearly basis.

We now count Splunk among our sponsors and we’re looking forward to rolling out Dániel’s work in October. Thank you Splunk and thank you to Joyce Morrell and Christy Wilson from Splunk for working with us to make this happen!

Search server release: 2012-09-18

September 18th, 2012

We’ve just updated our search servers with a new release. This release adds support for a new improved json format for the search server and will be publicly available after the next mbserver release. We also now output the date (in the XML/json) the index was last updated so you know how old the results received are. This will be exposed to the end-user in the web search results in an upcoming release of musicbrainz-server.

Thanks to Paul Taylor and Aurélien Mino for making this release happen!

Improvement

  • [SEARCH-232] – Search server should return information about when the indexes were last updated

New Feature

  • [SEARCH-226] – Add Support for Json format as described in http://wiki.musicbrainz.org/User:kuno/Web_Service/JSON
  • [SEARCH-227] – Add prettyprint option for Json (and XML)

Possible date change for our summit: 9-11 November 2012

September 17th, 2012

I’ve just found out that the Music Hack Day London conflicts with our summit in Barcelona. :( Given that a few people from MusicBrainz wanted to attend that Hack Day, we’re considering the possibility of changing our summit date to 9-11 November.

I’ve already contacted all of the people who signed up as potential attendees, but I wanted to throw this suggestion out to all of you who might consider going.

If you have a problem with the new date, please post a comment. If we dont get any significant conflicts, we may change the date.

Thanks!
