djmix_of

Indicates that all (or most of) the tracks of a musical work or the expression of a musical work were mixed together from all (or most of) the tracks from another musical work or the expression of a musical work to form a so called DJ-Mix. The tracks might have been altered by pitching (so that the tempo of one track matches the tempo of the following track) and fading (so that one track blends in smoothly with the other). If the tracks have been more substantially altered, the "mo:remix" relationship type is more appropriate.

The artist usually selected the tracks, chose their sequence, and slightly changed them by fading (so that one track blends in smoothly with the other) or pitching (so that the tempo of one track matches the tempo of the following track). This applies to a 'Mixtape' in which all tracks were DJ-mixed together into one single long track.

• ObjectProperty

download

This property can be used to link from a person to the website where they make their works available, or from a manifestation (a track or an album, for example) to a web page where it is available for download. It is better to use one of the three sub-properties instead of this one in order to specify wether the content can be accessed for free (mo:freedownload), if it is just free preview material (mo:previewdownload), or if it can be accessed for some money (mo:paiddownload) (this includes links to the Amazon store, for example). This property MUST be used only if the content is just available through a web page (holding, for example a Flash application) - it is better to link to actual content directly through the use of mo:available_as and mo:Stream, mo:Torrent or mo:ED2K, etc. Therefore, Semantic Web user agents that don't know how to read HTML and even less to rip streams from Flash applications can still access the audio content.

ean

The European Article Number (EAN) is a universal identifier for products, commonly printed in form of barcodes on them. The numbers represented by those codes can either be 8 or 13 digits long, with the 13-digit-version being most common. EANs form a superset of the North American Universal Product Code (UPC) as every UPC can be made an EAN by adding a leading zero to it. Additionally every EAN is also a Japanese Article Number (JAN). The identifiers were formerly assigned by EAN International which merged with Uniform Code Council (UCC, the guys behind the UPCs) and Electronic Commerce Council of Canada (ECCC) to become GS1.
