I can see where it gets messy when linking from individual subfields. I think it was a perfectly valid suggestion, and adding a standardised way to add URIs to (parts of) a MARC21 record would be welcome. On the other hand a lot of the code-subfields have implicit information about where the codes are supposed to come from (i.e the link might not be necessary).  A small change to MARCXML would ofcourse let it carry the URL in an attribute instead, which would make MARCXML better suited for transformation to RDF.

Is there an ongoing discussion somewhere on this?
