    Abstract
    For years, Mexico has had a distance learning system backed by television-signal-transmitted videos. The change to digital and computer transmission demands organizing the information system and its subject contents through a thesaurus. To prepare the thesaurus, an evaluation of existing thesauri and standards for data exchange was carried out, aimed at retrieving subject contents and scheduling broadcasting. Methodology for evaluating thesauri was proposed, compared with a virtual educational platform and a basic structure for setting up the information system was recommended.
