5. 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

6. 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
interoperability
