Identifiers are essential for accurate data exchange. Therefore, RIN supports a range of identifiers for different entities. Examples include ISRCs for sound recordings, ISWCs for musical works and ISNIs for parties such as writers, recording artists and sound engineers.
However, many such entities are also identified by proprietary identifiers. These identifiers can also be included in a RIN file and are expressed in two parts: the organisation that is responsible for allocating the identifier (the identifier’s “namespace”) and the identifier itself.
If a company that has allocated a proprietary identifier has been allocated a DDEX Party ID (DPID), and if the RIN Processor adding this proprietary identifier into the RIN File knows of this DPID, the namespace shall be the DPID.
Otherwise the RIN Processor shall be using a mnemonically sensible string to identify the company allocating a proprietary identifier. Below are two examples of this:
