XCRI is a project that aims to develop an XML specification called the Course Advertising Profile (CAP) for describing courses and exchanging course information between institutions. The CAP would allow institutions to populate websites and portals with course data from a single definitive source. There is interest from the education community in a standard for sharing course information. The XCRI project has involved developing and testing the CAP schema and examples of its implementation in aggregator websites and course brochures. Future work may involve submitting the CAP to a standards body and expanding it to support additional aspects of curriculum management.
