Rationale

LORs are not socially aware

Not growable in a Web2.0 basis

Not fully searcheable because metadata sometimes is not available

Only SW-based LORs are compatible with communities of users in the social web (2.0)

Maybe… Use authoring as the killer app of e-learning Use a new generation of authoring tools based on layers of abstraction, NOT LT-specs driven auth tools Search & retrieval based on metadata elements is no longer enough for e-learning resources cataloging and operation.
