In this article, the author discusses "CanCore," a learning resource metadata initiative funded by Industry Canada and supported by Athabasca University, Alberta, and TeleUniversite du Quebec, and describes the increasing range of international uses of the "CanCore" metadata for the indexing of learning objects. "CanCore" is designed to facilitate the indexing of online educational resources or Learning Objects (LO), by assisting project implementers and catalogers in the development of high-quality systems and indexing based on the IEEE Learning Object Metadata (LOM) standard. Other implementations of "CanCore" have been undertaken in a wide range of projects and educational contexts. This article provides a list of some of these projects, products and organizations, and their respective websites. In each case, a brief indication is provided of how the initiative has used "CanCore."
