In mid-August 2007, 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. The license has since been changed to a public domain one. Prior to the advent of this license and API, Discogs data was only accessible via the Discogs web site's HTML interface and was intended to be viewed only using web browsers. The HTML interface remains the only authorized way to modify Discogs data.
