Interoperability• Technical

– Synchronization of repositories– Architecture models (p2p, client/server, ..)– Updating and maintainance

• Social– Communities of contributors– Shared ontologies between communities– Better authoring tools

• Industry– Copyright models– LT specifications driven tools

LOR’s are a generalization of a Digital Library, not a particularization

Consequently

- New models to search and retrieve- IR techniques needed- Semantic interoperability as relevant as technical
