Representatives of the IEEE Learning Technology Standards Committee Learning Objects Metadata (LTSC-LOM) Working Group and the Dublin Core Metadata Initiative (DCMI) have signed a Memorandum of Understanding outlining the commitment to develop mutual interoperable metadata for technology-supported learning, education and training tools. The MOU signifies that a core set of specifications and accredited standards is emerging to support an interoperable infrastructure for worldwide e-learning technology. Ready access to comprehensive repositories of metadata is increasingly noted by developers of Web-enabled learning technology products as a critical factor in the next generation of learning and knowledge creation. However, to be useful, that metadata must be highly interoperable and reusable worldwide. The agreement signals a path forward for how education and training practitioners engaged in developing metadata can best support e-learning. Representatives from concurring projects sponsored by the following organizations support the joint effort between the IEEE LTSC-LOM and DCMI: ARIADNE (Alliance of Remote Instructional Authoring and Distribution Networks for Europe), EdNA (Education Network Australia), GEM (Gateway to Educational Materials), and the IMS Global Learning Consortium.
