SQI Meeting Minutes

SQI Meeting Minutes & Work Items Lugano, 2004-06-21

Attendees: Stefaan Ternier, Joaquin Salvachua (via Messanger), Germán Rivera (via Messanger), Zoltán Miklós, Tomaz Klobucar, Borka Jerman-Blazic, Bernd Simon, Daniel Ollmedia, Peter Dolog, Sam Guinea

- Bernd presented the new version of the API Specifications. The following comments were gathered: o The session ID specification shall be presented in the specs as one potential implementation example. Implementers shall have the freedom to choose how to create a session ID. o The requirements of the messaging layer (basis for API) shall be defined in the document. Good example: KQML specification. o We might want to rethink maxResults in the context of asynchronous search.

- SQI Network setup: o Progress report was made by Edutella (Daniel), Amazon Gateway (Zoltán), Ariadne (Stefaan), Celebrate (through Stefaan), and Polictecnico Milano Virtual Campus (Sam), EducaNext (Joaquin) --> presenters please send me your slides in case you had one. o Several nodes will be connected via Edutella. Ariadne is currently working on a federated search gateway, which will connect the Ariadne KPS, the Celebrate Network, and Merlot. o For the Edutella Network, WUW will install another rendezvous server (Daniel will get in touch with Zoltán) o All “finished” shall register under http://rubens.cs.kuleuven.ac.be/vqwiki-2.5.5/jsp/Wiki? SQIImplementationsRegistry. The registration shall include: repository name, contact person including contact details, link to WSDL files, query languages supported, short description of repository (purpose), short description of learning objects made available (access conditions, e.g. do I need to register? can everybody can register? etc. ..; number of learning objects; types of learning objects; subjects covered). Existing systems shall be extended by this information until the 1st of July. o All ProLearn-related systems shall be made available until the 1st of July. o Pending progress report from IMC/Clix and IBWW o Open work item for network spec.: We might want to think of network nodes, which provide cache functionality for particular learning resource types or subject disciplines. o Open work item for network spec.: query routing (e.g. how to avoid the creation of a routing circle so that requesting repositories get by themselves queried via the network without wanting it).

- A Use Case for the Network Search was developed (--> see attachment).

- A discussion on the Common Schema was held and first mapping exercises were performed. It was concluded that we need to distinguish between (see also follow up message by Erik): o Schema of concepts that can be used in a query: this schema defines the semantic capabilities of the network and shall be derived from the use case. o Results _list_ concepts: this set of attributes defines which metadata shall be return per learning resource in a result list. o Results format: shall provide a description of all attributes that can be used to describe a learning resource. o Repository profile: some attributes will be needed to query for profile properties o All ProLearn and Elena partners shall provide a mapping to the query schema until the 1st of July --> Find enclosed a revised mapping table for query schema and results list. For the results list a common XML/RDF and XML schema need to be provided. Germán can you take care of this?

- Your comments: Let me re-enforce that any comments are welcome at any time especially of those of you who did not participate in the Lugano meeting. We would especially appreciate any comments to use case, query schema, and result format before the end of this week (4th of July).

- Next meeting: To-be-announced (coordination with Erik D. needed)
