To choose suitable resources for personal competence development in the vast amount of open educational resources is a challenging task for a learner. Starting with a needs analysis of lifelong learners and learning designers we introduce two wayfinding services that are currently researched and developed in the framework of the Integrated Project TENCompetence. Then we discuss the role of these services to support learners in finding and selecting open educational resources and finally we give an outlook on future research.

4. Current Situation Distributed, unconnected repositories Unconnected learner communities Searching for OER is complicated, because learners have to know where to search. Learning communities are organized around repositories and not around topics or competence development goals.

Personal Recommender System (Drachsler et al. 2007) Our approach to the orientation problem for learners who use OER Latent Semantic Analysis (LSA) to compare resources in learner portfolios with resources in repositories.
