School Access to digital content like OER has expanded and open repositories play a significant role in this field, but to improve the use and reuse of these OER it is important to understand how they can be used. To link OER to practices, Universidade Aberta (UAb) is developing an OER-OEP ecosystem, which includes the
creation, description, preservation, sharing and possibility of reuse of educational resources used in open educational practices, that is, the articulation between resources and their didacticpedagogical contextualization, based on real pedagogical contexts of use. Besides, important aspects like quality through external validation and sustainability of the project are guaranteed considering the procedures that have been implemented. The case of UAb Open Repository, giving this kind of information, is an important tool to improve
the effective use of OER and can be considered an example of good practices, of transversal interest for
administrators of institutional repositories, teachers and other educational agents with an interest in open education.info:eu-repo/semantics/publishedVersio
