Abstract
Software product audits are knowledge-intensive tasks in which architectural knowledge plays a pivotal role. In the input stage of a software product audit, quality criteria are selected to which the software product should conform. These quality criteria resemble architectural tactics and can be viewed as a definition of the Soll-architecture of the product. Like tactics, the same quality criteria can be applied to different software products. However, there are currently no models that support the codification of quality criteria as reusable assets. In this work, we present an ontology that supports the reuse of quality criteria in the input stage of software product audits.
