MusicBrainz is a project that aims to create an open content music database. Uniform Resource Locator is an URI which also specifies where the identified resource is available and the protocol for retrieving it The MetaBrainz Foundation is a 501(c(3 tax-exempt Non-profit based in San Luis Obispo California that operates the MusicBrainz project Open content, a Neologism coined by analogy with " Open source " describes any kind of Creative work published in a format that explicitly allows Music is an Art form in which the medium is Sound organized in Time. Similar to the freedb project, it was founded in response to the restrictions placed on the CDDB. freedb is a Database of Compact disc track listings where all the content is under the GNU General Public License.

A Compact Disc (also known as a CD) is an Optical disc used to store digital data, originally developed for storing digital audio Metadata ( meta data, or sometimes metainformation) is "data about data" of any sort in any media ***************************************************************************************** * * [1]

Overview

MusicBrainz captures information about artists, their recorded works, and the relationships between them. Recorded works entries capture at a minimum the album title, track titles, and the length of each track. These entries are maintained according to a common style guide. Recorded works can additionally store information about the release date and country, the CD disc ID, an acoustic fingerprint for each track and have an optional free-form text field or annotation attached to them. An acoustic fingerprint is a digital measure of certain acoustic properties that is deterministically generated from an Audio signal, that can be used to identify As of Dec 31, 2007, MusicBrainz contained information about 350,718 artists, 534,986 releases, and 6. Events 406 – Vandals, Alans and Suebians cross the Rhine, beginning an invasion of Gallia. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. 3 million tracks. [2]

End-users can use software that communicates with MusicBrainz to tag their digital media files, such as MP3, Ogg Vorbis or AAC. MusicBrainz is a project that aims to create an Open content Music database MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a Digital audio encoding format using a form of Lossy data compression Vorbis is a free and open source, lossy audio Codec project headed by the Xiph Advanced Audio Coding ( AAC) is a standardized lossy compression and encoding scheme for Digital audio.

MusicBrainz initially used Relatable's patented TRM (a recursive acronym for TRM Recognizes Music) for acoustic fingerprint matching. A recursive acronym (or occasionally recursive initialism, and sometimes recursive backronym) is an Abbreviation that refers to itself in the An acoustic fingerprint is a digital measure of certain acoustic properties that is deterministically generated from an Audio signal, that can be used to identify This feature attracted a lot of users and allowed the database to grow at a fast rate. By 2005 it became obvious Relatable's fingerprinting solution didn't scale well to the millions of tracks in the database and the search for a viable replacement began. Year 2005 ( MMV) was a Common year starting on Saturday (link displays full calendar of the Gregorian calendar.

On May 12, 2006, Robert Kaye posted an announcement on the project's official blog about a partnership between MusicBrainz and MusicIP. Events 1191 - Richard I of England marries Berengaria of Navarre. Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. [3] Part of the agreement allows MusicBrainz to use MusicIP's MusicDNS service for acoustic fingerprinting (PUIDs). MusicDNS is an Acoustic fingerprinting service and a Software development kit provided by MusicIP. PUID or Portable Unique IDentifier is a Unique identifier used by MusicIP and given by MusicDNS to identify a song After a grace period of 6 months, TRMs will be phased out and MusicBrainz will rely solely on PUIDs. MusicBrainz uses RDF/XML for describing music metadata, which is available for automated processing via HTTP GET and POST methods according to REST architectural style for distributed hypermedia systems. The Resource Description Framework (RDF is a family of World Wide Web Consortium (W3C Specifications originally designed as a Metadata Data Don't change "Extensible" Hypertext Transfer Protocol ( HTTP) is a Communications protocol for the transfer of information on the Internet.
