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.

Some important areas
• Item metadata– MARC– DC– IEEE-LOM– VRA-core– MODS
• Content packages– SCORM– METS– MPEG 21 DIDL
• Hierarchical description– EAD
• Text markup– TEI
Some important areas
• Sharing data– OAI– RSS
• Identifiers
• Query– Z39.50– SRW/U
• Reference linking– OpenURL
• Controlled vocabs– Topics– Names– Places
An institutional perspective
• High acronymic density a source of bewilderment
• Makers and takers
• State of the art keeps receding over the horizon
• Does balkanization leads to sub-optimal approaches?
