Learning Objects Repository
LOVE
Federation of Distributed Repositories
Federation of different document types, formats, structures, styles, and semantics
Federation of different classification and categorization
Federation of search protocols, database and repository management systems
LOVE (Learning Object Virtual Exchange)
Collection: reviewed & unreviewed educational materials
Sharing learning objects and educational materials among teachers.
Collaborative workspace for students, parents (K-12), reviewers and teachers.
Cooperative for IP rights of local teachers and authors.
Learning and assessment objects
Delivering learning objects based on learner profiles.
Generating assessment objects based on learner profiles.
Assessment feedback on learning objects.
User-Centered Digital Libraries
System-centered vs. user centered digital libraries
Information seeking process is incremental and interactive
User-centered evaluation - a user/system/information interaction model
Internet-logged user data analysis
