Coming out of this week's IMS meeting, Ray Henderson has a good post up describing the progress Blackboard was able to demonstrate toward support of the IMS Common Cartridge (CC) and Basic Learning Tool Interoperability (BLTI) standards. Sometimes it's hard to tell from a distance how committed a company is to implementing a standard---particularly one that's still under development. Something to look for is regular public demonstrations of progress within the context of the standards body. The work Blackboard unveiled this week bodes well. The CC demo (import only at this point) was developed by Blackboard itself, while the BLTI demo was implemented as a building block by Steven Vickers at the University of Edinburgh (and released under the GPL open source license). Ray promises an update on the progress at the BbWorld conference in July.
