Jakob does this make sense?

Just having read Joel Spolsky's article about Architecture Astronauts that Mike pointed to [1] I hesitate to propagate what you can all do with DAIA. But your use case makes sense if you want to offer services provided or mediated by a specific institution (such as a library) with a specific publication.

Inspired by your idea to combine OpenURL and DAIA I update the DAIA perl library [2] and hacked a DAIA server that also understands some very limited OpenURL (it only knows books with ISBN):

You can look up which library has a specific publication in the GBV library union by its identifier:


or by OpenURL


Have a look at the simple source code of this script at


I want to stress that this demo DAIA server does not use the full expression power of DAIA, in fact it does not provide any availability information at at - but you hopefully get the concept.
