Abstract— The convergence of digital media offers an integration of ICT focused on telecommunications and multimedia domain(under responsibility of the Moving Picture Experts Group, ISO/IEC JTC1 SC29) and the ICTE (the ICT for Education), managed by
the ISO/IEC JTC1 SC36, highlighting the MPEG standards, employees as content and metadata to the multimedia Digital TV and thetechnologies applied to e-Learning. Regarding this, there is the problem of developing an interoperable matching for normative bases,
achieving an innovative proposal in the convergence between digital telecommunications and applications for e-Learning, alsoessentially multimedia. To reach this purpose it is proposed to create a standard ontology of interoperable metadata for web, digital
TV and extensions for mobile devices based on the integration between MPEG-21 and SCORM metadata standards. The methodology
used consists on building the ontology MPEG-21 SCORM which can be achieved on making a correspondence through the XPathlanguage, managed by the W3C. The employ of the XPath language is desirable for matching and mapping both metadata schema
patterns – integrating MPEG-21 (mostly Digital Item Declaration Language) and SCORM metadata schema. The practical purpose isthe creation and storage of objects for use in digital telecommunications as Digital Television, in an interoperable way with the eLearning industry, here as description metadata for all sorts of media and hypermedia to create learning objects.
