Accessibility metadata to improve OER adaptability

This work presents the study of LOM-ES as standard metadata for accesibility and its correspondence with the standard model IMS, in order to facilitate the OER adaptability. This metadata is analized inside the virtual environment, the repositories and paths between them. OERs can get improvements or adaptations from comments about the accesibility originated on virtual environments. This contributes to an adequation process over students preferences. Finally is presented a proposal about a set of accessibility metadata on virtual environments embodied in a Moodle prototype.
