The document discusses several metadata standards for online learning resources, including the IEEE Learning Object Metadata Standard (LOM), Dublin Core, and the emerging ISO/IEC Metadata for Learning Resources Standard. It analyzes usage patterns of LOM elements based on a survey of existing metadata records and finds that elements describing intellectual content and file characteristics are used most frequently. Dublin Core is positioned as a simpler alternative to LOM that is better aligned with semantic web technologies through its use of RDF. The new ISO standard aims to provide compatibility with LOM and Dublin Core while addressing accessibility, multilingual support, and other needs.
