Metadata switchMetadata switch

• A set of projects which explore services which• … add value to metadata

– through transformation, enrichment, recombination, …

• .. and are delivered as modular, web-based machine-to-machine applications (web services).

Why?Why?

• Libraries• Libraries are creating more metadata for more types of

material. • They are using different metadata schema and content

standards • They are using different systems and workflows.

• For OCLC• Much of the value of what we offer is embedded in

integrated systems which meet a central need, but which may not support the changing working patterns of all our potential users.

• We need to explore how to break down services into components which our users can build back up within their environments and workflows

• We also need to figure out how to make our existing investment in structured metadata work more for us by mining, developing, and exposing relationships across documents and other resources.

Some objectivesSome objectives

• What expectations do you have for distributed service environments?

• What metadata/knowledge organization services would be useful in these environments?

• How should they be delivered?• What role do you see OCLC play?• Are there any collaborative take-aways?

Some recurrent themesSome recurrent themes

• Registration• Levels of granularity and aggregation• Quality expectations / noise tolerance• Content standards• IPR issues in a ‘recombinant’ environment• Licensed/open source
