Resources ManagementChallenges
Increased user persistence : simplicity, real networking, usability, interoperability, flexibility
Easy integration into learning environments Static and dynamic aggregation: open source and Web
services Encapsulating resources & abstract language for control,
adaptivity, repurposing Integration of advanced MM/3D/VR learning objects: MPEG-7
and CANCORE Data mining into LO repositories and knowledge management

Actual Potential (Bêta -Q.1 - 2002)
Open, multi-actor and multi-model Telelearning system Integrated management of courses and resources Function as tree structure (Activities + knowledge) Embedded assistance to operations IMS-CANCORE metadata (XML and SQL data base)
Limitations to overcome Not yet a large control on resources (abstract resources) Superficial interoperability (semantic web and web services) Actors partially coordinated (not by visible processes) Limited adaptive assistance (expand the actual advisor) Integration between Explor@ and other LMS (Ex: WCT) Meta-functions to integrate design, development, delivery
5- Future of Explor@
© LICEF
Main goals Autonomous resources and system components,
reusable in different contexts, for different actors Encapsulate in an abstract layer, manipulate and
enable aggregation at a semantic Web level Interactive graphic models as a meaningful
context to help actor coordination Integration methodology for portals, platforms,
and telelearning services Explor@ as part of a distributed network of LSPs
interoperated through web services
