Three points:

1) Directly, I regard datatypes as a closed book. Others have explained why this is the case, but put simply, using custom datatypes is a pain in the neck and can be easily avoided.
2) bibo:isbn works fine.
3) What are the use cases for ISBNs? I'm guessing not "identifier" in any strict sense.

All,
 
We're thinking about modeling identifiers (and other properties?) in two ways:
 
1) generic property with a more specific data type:
 
                bf:identifer  "9780394856308"^^http://example/org/isbn13
 
or
 
2) specific property:
                                               bf:isbn13 "9780394856308"
 
where 'bf:isbn' is a subproperty of 'bf:identifier'.
 
How does the community feel about these two options, and why?
 
Thanks,
 
Nate
