Increase the interoperability of LOM application profiles

The IEEE LOM is now standardized since July 2002 but it is not the only one standard used to describe learning objects. Application profiles based on the LOM and other educational metadata schemas coexist. This established fact leads to a lack of interoperability between descriptions based on different schemas. To solve this problem, we propose a solution based on the ISO 11179 standard, allowing the description of a conceptual level independently of any particular representation. Thus, each educational metadata schema can be specified as an "instantiation" of a unique educational conceptual level linking them.
