At the BL we have developed a common format called the BL Application Profile (BLAP). This is based on the DC Library Application profile. In turn, for metadata describing specific materials or for a specialised purpose, the BL Profile is further refined. For example, we have a special application profile for sound which deals with describing a range of recordings from commercial products, broadcasts, wildlife, environmental sounds and interviews (BLAP-S). If an SRU service delivers this records conforming to this profile, the client might like to know that the particular record schema (dcx) conforms to Qualified Dublin core, the DC Library Application profile, BLAP and perhaps BLAP-S.
