Discogs
Discogs (short for discographies) is a website and crowdsourced database of information about audio recordings, including commercial releases, promotional releases, and bootleg or off-label releases. The Discogs
Discogs servers, currently hosted under the domain name discogs.com, are owned by Zink Media, Inc., and are located in Portland, Oregon, US. While the site lists releases in all genres and on all formats, it is especially known as the largest online database of electronic music releases, and of releases on vinyl media. Discogs
Discogs currently contains over 9 million releases, by over 5 million artists, across over 1 million labels, contributed from nearly 374,000 contributor user accounts—with these figures constantly growing as users continually add previously unlisted releases to the site over time.[3][4]

History[edit] The discogs.com domain name was registered on 30 August 2000,[5] and Discogs
Discogs itself was launched in November 2000 by programmer, DJ, and music fan Kevin Lewandowski originally as a database of electronic music.[6] He was inspired by the success of community-built sites such as Slashdot, eBay, and Open Directory Project, and decided to use this model for a music discography database.[citation needed] The site's original goal was to build the most comprehensive database of electronic music, organized around the artists, labels, and releases available in that genre. In 2003 the Discogs
Discogs system was completely rewritten,[7] and in January 2004 it began to support other genres, starting with hip hop. Since then, it has expanded to include rock and jazz in January 2005 and funk/soul, Latin, and reggae in October of the same year. In January 2006 blues and non-music (e.g. comedy records, field recordings, interviews) were added. Classical music started being supported in June 2007, and in October 2007 the "final genres were turned on" – adding support for the Stage & Screen, Brass & Military, Children's, and Folk, World, & Country music genres, allowing capture of virtually every single type of audio recording that has ever been released. On 30 June 2004, Discogs
Discogs published a report, which included information about the number of its contributors. This report claimed that Discogs
Discogs had 15,788 contributors and 260,789 releases.[8] On 20 July 2007 a new system for sellers was introduced on the site called Market Price History. It made information available to users who paid for a subscription – though 60 days information was free – access to the past price items were sold for up to 12 months ago by previous sellers who had sold exactly the same release. At the same time, the US$12 per year charge for advanced subscriptions was abolished, as it was felt that the extra features should be made available to all subscribers now that a better, some may say fairer, revenue stream had been found from sellers and purchasers. However, at the beginning of 2008, the Market Price History was also made free of charge for all users, still giving up to a 12-month view of historical sales data for any release.

Other projects[edit] In mid 2014, a side project website called VinylHub[11] was started, in order for users to add record shops and stores from around the world, with information concerning location, contact details, what type of items they stocked, et al. In late 2014, the company released two new beta websites. Filmogs[12] is where users can submit both Films and Releases as separate entities, meaning users could add their physical film collections and/or add films generally to the database, and track them as part of their collection or similar. Gearogs[13] lets users add and track music equipment like synths, drum machines, and other electronic music making equipment. At the start of 2015, the company began another beta project — Bibliogs.[14] Users can submit information about their books, physical or electronic, different versions and editions, and also connect different credits (writers, illustrators, translators, publishers, etc.) to these books. 21,000 books were submitted by the end of 2016. The project was in beta phase until 15th August 2017[15] when it reached more than 31,000 book titles, and rebranded without clear explanation to Bookogs.com, obviously because of legal issues with the old name Bibliogs, and removed 'Beta state' notice from the main page. The next day the 'Marketplace Beta' feature was presented[16]. Comicogs[17] launched around the same time as Bookogs, as a means for comic collectors and enthusiasts to catalog their collections and create an archive of comic releases. Similar to Bookogs, users can contribute comics, manga, graphic novels, and strips to the database, along with information on credits, publishers, writers, etc. 18,000 comics were submitted by the start of 2018. The Comicogs marketplace was launched on 23rd August 2017[18], allowing users to buy and sell comics from across the world. In September 2017, the company launched Posterogs.[19] Posterogs was the only Discogs
Discogs site to launch a database and marketplace simultaneously.[20] The scope of Posterogs was left broad at the time of launch, with the company opting to let the community define what type of posters should be included in the database. As users have contributed posters to the database, the primary focus seems to be music posters, such as gig posters, album promo posters, and tour posters - which is in keeping with Discogs' music theme, though there are also many film posters in the database. As with all other databases, users can save posters to their 'Collection' and 'Wantlist' and buy and sell in the marketplace. API[edit] In mid-August 2007, Discogs
Discogs data became publicly accessible via a RESTful, XML-based API and a license that allowed specially attributed use, but did not allow anyone to "alter, transform, or build upon" the data.[21][22][23] The license has since been changed to a public domain one. Prior to the advent of this license and API, Discogs
Discogs data was only accessible via the Discogs
Discogs web site's HTML
HTML interface and was intended to be viewed only using web browsers.[24] The HTML
HTML interface remains the only authorized way to modify Discogs
Discogs data.[22] On 7 June 2011 version 2 of the API was released.[25] Notable in this release was that a license key was no longer required, the default response was changed from XML
XML to JSON, and the 5000 queries per day limit was removed (although a limit of 2000 image lookups per days was introduced). On 1 November 2011 a major update to version 2 of the API was released.[26] This new release dropped support for XML, data is always returned in JSON
JSON format, however the monthly data dumps of new data are only provided in XML
XML format. On 1 February 2014 Discogs
Discogs modified their API so that image requests will now require OAuth
OAuth authorization, requiring each user of third-party applications to have a Discogs
Discogs "application ID", with image requests now limited to 1,000 per day. Additionally the Premium API service was dropped.[27] On 24 June 2014 Discogs
Discogs deprecated their XML
XML API in lieu of a JSON-formatted API.[28] Discogs
Discogs also allows full XML
XML downloads of its Release, Artist, and Label data through the data.discogs.com subdomain. The recommendations API is not publicly available.[29] Contribution system[edit]

The data in Discogs
Discogs comes from submissions contributed by users who have registered accounts on the web site. The system has gone through four major revisions. Version One (V1)[edit] All incoming submissions were checked for formal and factual correctness by privileged users called "moderators", or "mods" for short, who had been selected by site management. Submissions and edits wouldn't become visible or searchable until they received a single positive vote from a "mod". An even smaller pool of super-moderators called "editors" had the power to vote on proposed edits to artist & label data. Version Two (V2)[edit] This version introduced the concept of "submission limits" which prevented new users from submitting more than 2-3 releases for moderation. The number of possible submissions by a user increased on a logarithmic scale. The purpose of this was two-fold: 1) it helped keep the submission queue fairly small and manageable for moderators, and 2) it allowed the new user to acclimatise themselves slowly with the many formatting rules and guidelines of submitting to Discogs. Releases required a number of votes to be accepted into the database - initially the number of votes required was from 4 different moderators but in time the amount was decreased to 3 and then 2. Version Three (V3)[edit] V3 launched in August 2007. Submission limits were eliminated, allowing each user to submit an unlimited number of updates and new entries. New releases added to the database were explicitly marked as "Unmoderated" with a top banner, and updates to existing items, such as releases, artists, or labels, were not shown (or available to search engines or casual visitors) until they were approved by the moderators.[30] Version Four (V4)[edit] This system launched on 10 March 2008. New submissions and edits currently take effect immediately. Any time a new release is added or old release edited, that entry becomes flagged as needing "votes" (initially, "review," but this term caused confusion). A flagged entry is marked as a full yellow bar across a release in the list views and, like version three, a banner on the submission itself – although, initially, this banner was omitted. Any item can be voted on at any time, even if it isn't flagged. Votes consist of a rating of the correctness & completeness of the full set of data for an item (not just the most recent changes), as assessed by users who have been automatically determined, by an undisclosed algorithm, to be experienced & reliable enough to be allowed to cast votes. An item's "average" vote is displayed with the item's data.[31] The ranking system has also changed in v4. In v3, rank points were only awarded to submitters when a submission was "Accepted" by moderator votes. While in v4, rank points are now awarded immediately when a submission is made, regardless of the accuracy of the information and what votes it eventually receives, if any.[32] Discogs-aware metadata software[edit] Tag editors[edit] Main article: Tag editor
