Technology Transition

Technology Transition

We transitioned the UniCon toolset to the University of Oregon. It was used in a Masters course on Software Architecture to teach the students about architectural abstractions and how to describe systems using them.

We transitioned the Aesop toolset to Lockheed-Martin for packaging and incorporation in the EDCS demonstrations for "Demo Days."

David Garlan prepared a tutorial entitled "Architectural Description and Analysis," which will be given at the European Software Engineering Conference in September.

We applied formal modeling tools to DMSO HLA, generating significant feedback, which has had an impact on their published architectural specification.

We made the following systems and prototypes publicly available. Some can be obtained over the WWW, and for these we have included the URL.
