Illuminatingthesedifferencesisapreparatory stepforarchitecturemigrationinwhichpreviouslydevelopedartefactsare reusedforreasonsofefficiency. Ourtheconformancecheckingsystem (CCS)isnon-intrusive. Itcoordinatestheinteractionbetweenthearchitectureandtheimplementationdomainofexpertise,whileregardingthem autonomously. Itusesreadilyavailable,possiblytailored,technologyfor theactualimplementationofCCS.Assuch,themaincontributionsofthis chapterare: •agenericprocessforconformancecheckingofarchitecturalviews; •extensible metamodels for C&C and module viewpoints, including mappingsfromimplementationandarchitecturalartefacts;and •ademonstrationofhowtocombinedifferenttypesoftechnologies (insideandoutsidethemodelwaretechnologicalspace)intoanintegratedapproach, whilereusingseveralexistingmetamodelsand transformations Althoughourapproachislargelyautomated,checkingtheconformance forparticulartypeofviewsmightrequireaspecificapproach. Still,the CCSprovidesagenericprocessbasedonacommondesign-spaceviewpoint. TheCCSreliesonacleardefinitionofassociatedmetamodelandthemappingsfromthearchitecturalandimplementationartefactstothiscommon metamodel. Thedesign-spacemetamodel(e.g., Figure6.6onpage113)captures checkableconcepts,whicharetheconsensusbetweenverifyingabstract propertiesofthearchitectureandemergingpropertiesoftheimplementation.Possiblediscrepanciesbetweenthetwoarerevealedasmismatches betweenthederivedconformancemodelsandtheimpactofamismatch.
