摘要:In the present article we illustrate the choices taken by the Italian EPICT Secretariat (European Pedagogical ICT License) in order to archive and share the lessons plans developed by EPICT participants during the EPICT Courses. In particular, we present: 1) a set of metadata able to describe the learning resource lessons plan 2) and the advantages in using Web 2.0 features in order to develop a lesson plan repository. What we want to underline in the present article are two aspects of the development of a resources repository process: the assignation of descriptors and the repository dynamicity. When an author inserts a resource he is doing what we propose to defne as a “primary metadatatation”. From the repository user’s point of view, we consider a repository more useful if it is able to “grow” in accordance with the user’s needs and orientations. We can obtain this kind of dynamicity if the users themselves, after consulting a particular resource, are capable of adding new descriptions to the metadata and of leaving comments regarding the resources consulted. We propose to defne the contribution given by repository users as “secondary metadatation”.
