Since I complained recently about the IMS needing to open up more, it’s only fair that I should give credit when they actually do it. Chuck Severence, who now works part-time for the IMS, has a public test site up for people who want to test against a subset of the forthcoming Learning Tool Interoperability specification. Now, the full specification drafts are still non-public (to the extent that they even exist–LTI is still under active development) but, to be honest, hardly anybody reads the full spec anyway. What Chuck has done is much more useful because he’s providing sufficient documentation and tools for people to actually start building and testing LTI-compliant tools without a lot of extraneous gobbledygook. All it needs now is a feedback forum, and the IMS will suddenly have a very open and results-oriented (though perhaps not yet comprehensive) process for non-IMS members to provide feedback on specs in development.
Brilliant work. Really, a very big step forward.
On a side note, Chuck mentions the use of REST in the documentation. Thus far, the IMS has been pretty SOAP-heavy in its approach to web services. If the LTI group is indeed making judicious use of REST (which would make particular sense given the nature of what they’re trying to do) then that also is a Very Good Thing.
