Integration of Heterogeneous Information Sources into a KRMS for Lifelong Learning E. Demidova, S. Ternier, D. Olmedilla, E. Duval, M. Dicerto, K. Stefanov and N. Sacristán

Contents Introduction TENCompetence Knowledge Resource Management System Challenges & Architecture Conclusions and Further Work

Introduction TENCompetence Support lifelong competence development Establish technical and organisational infrastructure Use open-source standard-based innovative technology KRMS as a basis for the TENCompetence infrastructure Ensure availability, exchange and use of KR Enable learners to share resources Integration of heterogeneous information sources

Scenario

TENCompetence KRMS: Challenges Search in many information sources Time consuming More than 50% of searches are not successful Exploit emerging social applications Integration of heterogeneous KR management platforms LO repositories P2P networks (user’s desktop resources) Web2.0 resources Organize results (ranking, recommendations) Other activities (publishing, repository management) Standard interfaces required

TENCompetence KRMS: Our Approach Specification of common interfaces Search, publishing, repository- and user management Service Oriented Architecture 3-Layered Architecture Repository Layer Service Layer Client Layer Benefit from social aspects Web 2.0

TENCompetence KRMS Architecture Service Layer Client Layer Ariadne LeX Lobster FlickrYouTubeDSpace search Federated Search Engine wrapper P2P (LionShare) repository management publishing session management Registry Repositories GUI x LionShare peer publishing search Repository Layer user management User Database

Repository Layer Integrated information sources P2P Network (e.g. LionShare) LO Repositories (e.g. Ariadne) Web2.0 tools (e.g. YouTube) Interfaces for Search and Publishing Simple Query Interface (SQI) Simple Publishing Interface (SPI) Ariadne LeX Lobster FlickrYouTubeDSpace wrapper P2P (LionShare) KRMS Repository Layer

Service Layer Combination of P2P and Centralized Repositories Inclusion of desktop resources Local / remote resource management and sharing Repository and session management services Interfaces for repository- and user management Federated search engine SQI KRMS Service Layer search Federated Search Engine repository management publishing session management Registry Repositories

Client Layer Stand-alone application LionShare Peer Sharing of local resources Web-based Web services for a wide range of applications  LMS Central entry point  No software installation KRMS Client Layer GUI x LionShare peer publishing search

Conclusions Identification of requirements on KRMS for lifelong competence development 3-Layered architecture Integration of various information sources Services  Search, publishing  Repository and user management Local and remote resource management Interfaces SQI-based search Lack of the standards for other services

Further Work Further work on interface refinement and validation Further integration of Web2.0 tools Validation of KRMS as a part of the overall TENCompetence infrastructure
