Web pages describing an XML format for the exchange of course information. I think that XCRI is a step in the right direction, however I would sound a note of caution here. The reason I suggested RSS is that millions of people already have RSS readers, and robust RSS parsers exist in pretty much every computer language. XCRI does not appear, from the documentation, intended to be used in this way. So courses advertised in XCRI will not be readable in RSS readers. Designers should be careful to resist the temptation to try to include all possible data in a syndication format. That said, even an approach such as XCRI is infinitely better than having people from the institution complete forms on some vendor or government website.
