Re-use of existing identifiers as ISCC components.

[titusz]

It would be possible to re-use (re-encoded) existing identifiers as separate or replacement-components in the ISCC Scheme. For example an ISBN-13 could be encoded to the ISCC component format. Of course such a component would not be similarity-preserving, but that is not an absolute requirement. The Instance-ID for example is also not similarity-preserving. I see at least the following requirements for such an integration:

• The existing standard identifier can be encoded in 64-bits.
• The ISCC standard assigns custom self-describing component header for the existing standard identifier within the ISCC scheme.
• An agreement can be found about how and where the existing identifier is placed within the structure of a fully qualified ISCC Code.
• The respective standards body is interested in and agrees to such an integration.

Interested standard bodies are invited to add to this discussion or propose integration of their identifiers into the ISCC Scheme
