12. The computer software product according to claim 10 , wherein the re-evaluation event comprises an alteration in one of the actual semantic concerns.
10. A computer software product for representing software, including a non-transitory computer-readable storage medium in which computer program instructions are stored, which instructions, when executed by a computer, cause the computer to perform the steps of: defining actual semantic concerns relating to the software; constructing a plurality of models representing respective ones of the actual semantic concerns and actual semantic inter-relationships therebetween, wherein the models have model elements comprising semantic elements and conform to a meta-model, and wherein the actual semantic concerns comprise dynamic actual semantic concerns that are subject to updating, and an n-ary relationship exists between at least one group of the model elements that comprises a set of the actual semantic concerns; executing a graphic interface to display a graphic representation of the models; constructing semantic queries to validate the models; detecting a re-evaluation event; responsively to the re-evaluation event making a revision of the graphic representation to conform the dynamic actual semantic concerns to the re-evaluation event; conforming the models with the revision of the graphic representation, updating the semantic queries in compliance with the conformed models; and executing the updated semantic queries to determine whether the software violates a predetermined validation rule.
