Differences from GBB

GBBopen is a new design based on the concepts that were explored in the UMass Generic Blackboard system and the commercial GBB product. It is not an updated version of the GBB product. Nevertheless, the non-graphical portion of most GBB applications can be migrated to GBBopen with minor effort.

GBBopen design decisions and syntax that diverge from those made for GBB are surveyed below. This list is not complete and new items may be added as the GBBopen Project moves forward. Comments are welcomed at comments@GBBopen.org.
