This paper presents a description of the metadata harvester software development. This system provides access to reliable and quality educational resources, shared by Mexican Universities through their repositories, to anyone with Internet Access. We present the conceptual and contextual framework, followed by the technical basis, the results and future work. This paper is based on the experience gained from working with the technical committee of the project sponsored by CUDI-CONACYT titled: Metasearch of Educational repositories to Promote the Use of Learning Objects and Open Educational Resources: Best Practices.
