Five years ago, every discussion on interoperability issues in digital collections was at the same time the discussion on Z39.50. While if we talk about interoperability today, we will certainly mention Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Still, it does not mean that OAI-PMH could “replace“ Z39.50, because each of those has its own area of application which only partially overlap. Z39.50 is very sophisticated (and demanding) standard which enables distributed or “broadcasting“ searching. It means that information query is simultaneously sent from one place to multiple databases. On the other hand, interoperability concept which is enabled by OAI-PMH is based on metadata harvesting mechanism. OAI-PMH divides the world on “data providers“ and “service providers “. Data providers expose metadata about materials they contain, while service providers harvest those metadata, organize them and build new services on top of them. Metadata schema that OAI-PMH requires as obligatory is Dublin Core Metadata Element Set (coded in XML), but other metadata schemas employment is also possible (and suggested). The protocol itself is easily implemented and “low-barrier “. Originally, it is born in the context of reforming scholarly communication. Interoperability in the network of eprint archives needed to be established. The data that those archives contained were irretrievable via existing search engines; they were hidden inside “the deep web“. Very soon it became clear that the protocol is useful not only in the context of scholarly communication, but also in numerous and various projects in libraries, museums and archives. Among implementers of OAI-PMH we can find, besides subject based and institutional eprint archives, subject gateways, library WebPACs, electronic theses and dissertations collections, publishers, museum and archives collections. Materials contained can be text (abstracts or full texts), images, video, raw data, software etc. But, although the list of data providers that have implemented the protocol is longer every day, the real test of applicability and usefulness of the protocol is development of new innovative service providers, in all the above mentioned areas.
