The use case clarifies perfectly.

Totally feasible.  Well, I should say "totally feasible" with the caveat 
that I've never used the Worldcat Search API.  Not letting that stop me, 
so long as it is what I imagine it is, then a developer should be able 
to perform a search, retrieve the response, and, by integrating one of 
the tools advertised on the schema.org website into his/her code, then 
retrieve the microdata for each resource returned from the search (and 
save it as RDF or whatever).

If someone has created something like this, do speak up.

Yours,

Kevin
