  3. Interoperability as recombinant potential • Can I • navigate across several databases by subject, by name, by place, by resource type, by educational level? • add a document to a repository? • add a repository to a distributed query? • fuse metadata from one database with another? • assemble these resources into a learning package? • embed an interactive service in my exhibition, my reading list, my campus portal? • ingest a content package into an archive? • take a content package out of an archive in 10 years time? • cite a document in a repository? • bring resources into my own workspace? • With • as little custom work as possible • as little precoordinated agreement as possible

  4. Interoperability is an economic issue • Extract maximum value from investment in • Data (metadata and content) • Services • By ensuring that they are • Sharable • Reusable • Recombinable

  5. Interoperability is an economic issue • Allow users focus on productive use of learning and research resources rather than on the messy mechanics of interaction. • Allow resource managers develop routine approaches.
