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