OK, Now I think I see where we're missing each other. Right now, IFLA is
not thinking about registering (or creating identifiers for) the FRBR
"attributes," just the entities and relationships. I'm not sure that
the attributes make the cut... and they aren't the same as the
properties that RDA has defined. RDA properties have been assigned to
particular FRBR entities (Groups 1 and 2 only, since RDA didn't do Group
3) in the RDA documentation, but there isn't complete agreement within
the cataloging community as to which properties go with which FRBR Group
1 entities. So what RDA online is experimenting with is applying the
FRBR entities as classes to RDA properties in an application profile
that brings together RDA 'data elements' (properties in RDF) and FRBR
entities (classes in RDF). (I haven't seen the result yet in the
http://metadataregistry.org so I'm unclear on how the FRBR relationships
will be used. I think they've been registered as properties.)
I'm not at all sure what will happen with the FRBR attributes that are
in the FRBR document, but they seem to have been rejected by the JSC in
the RDA process. Nor can I figure out what's going to happen when the
FRAD draft is made official. FRAD essentially includes all of FRBR plus
some other properties and relationships.
Now bibo has many attributes that might be the same as RDA attributes,
or that could at least have some meaning within the FRBR defined
classes. FRBR entities could be used with bibo, if the idea for RDA in
the http://metadataregistry.org works, by creating an application
profile for bibo + FRBR classes.
