Framework for Logging and Analyzing Modeling Events


FLAME is an extensible collaborative software design framework that provides facilities to detect design-level conflicts in a proactive way, i.e., before architects manually perform detection. FLAME has an extensible architecture that provides facilities via which the modeling tools and consistency checkers appropriate for the target system's domain can be integrated. FLAME captures modeling changes as they are made, performs a trial merging and conflict detection in the background in order to immediately detect newly arising conflicts, and presents the results to the architects. Also, FLAME explicitly deals with the potentially resource-intensive computations necessary for high-order conflict detection by parallelizing and offloading the burden to remote nodes. Moreover, by implementing its novel algorithm that prioritizes instances of conflict detection, FLAME guarantees that the outstanding conflicts at a given moment can be detected in a reasonable amount of time even when the available computation resources for conflict detection are scarce.
