1. Select resources in groupings

2. Reference with metadata and annotate

3. Publish new local resources and reference them

4. Integrate resources in actor’s environment

5. Associate resources to functions

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
