Dutch Educational Content Chain
3
Educational Content Broker Interoperability between suppliers and users
4
Suppliers Cultural Heritage Institutes –Dutch institute for Sound and Vision –National Archive –Musea Publishers –Traditional –Internet-based Private collections –Content creation portals –Electronic Learning Environments –Educational Repositories
5
Implementors Content Creation Portals –Content Corner –Webmaker E-Learning environments –Teletop, –Moodle, –StudieWeb, –Sharepoint, –(N@tschool, It’s Learning) Education related mashups –Davindi, –Samen Zoeken, –Onderwijs Media Platform, –Digischool, …
6
Current partners sharing 190,000+ metadata records
7
Making interoperability work Both technically and semantically
8
Technical Interoperability Interfaces In: OAI PMH Out: SRU/SRW, SRU Drilldown, RSS Query 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
9
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
10
Recent enhancements (2007) Metadatastructure X to CZP Transformation facility (XSLT) Static collection ingest facility (xml- upload) as an alternative to harvesting (initial fase only!)
11
Architecture Search Engine Metadata Transformer OAI PMH SRU/SRW, RSS Portalse-Learning Env.other Edu-Mashups Edurep Content Creation Tools Repositories Static sets CZP

Implementation Support - Edurep Demonstrator
14
Edurep User Group Members Suppliers Implementers Kennisnet Main responsibilities Evaluation Roadmap decisions Pollution control Enforcing CZP compliance among members
15
Roadmap 2008 (1) Support for Outbound OAI PMH –Allowing implementors to do their domain specific things –Enabling connection to international networks, such as Learning Resource Exhange (LRE), Ariadne, GLOBE
16
Roadmap 2008 (2) Social Metadata Brokering (experimental) –Collecting and distributing: Tags Ratings Peer reviews In relation to more formal metadata
17
Roadmap 2008 (3) Automatic Metadata Extraction (experimental) object + context > CZP Objecttypes: –Text –Video
18
Open source software components Search Engine + harvester: –Meresco (www.meresco.org)www.meresco.org Metadata storage + oai provider: –Fedora (www.fedora.info)www.fedora.info –Proai (proai.sourceforge.org)proai.sourceforge.org Metadata transformer –Future Kennisnet OS-component (workflow requires more fine-tuning)
