In: OAI PMHOut: SRU/SRW, SRU Drilldown, RSSQuery language: CQL
Fundamental choices
- Open, widely accepted Standards only - Harvesting, no federated Search- No implementor specific features- No supplier specific exclusion rules- Implementors may target specific sets in Edurep
Semantic Interoperability
• Content Zoekprofiel (CZP)Dutch IEEE-LOM application profile agreed upon
by the joint educational partners.
• A growing set of standardized vocabularies (vdex’s)
Educational levels, disciplines, …
Fundamental choices–Suppliers are obliged to conform to CZP
–Implementors can anticipate CZP metadatastructure in
their query building and UI design
Recent enhancements (2007)
• Metadatastructure X to CZP Transformation facility (XSLT)
• Static collection ingest facility (xml-upload) as an alternative to harvesting (initial fase only!)
