Service-oriented architectures (SOA) offer a conceptual and technical solution for many problems. However, the realizationand even more the management of a SOA often remains a very hard task. A continuous evaluation of existing services andservice candidates is necessary to implement, maintain and enhance a SOA. This is far from being trivial because of thesemantic gap between requirements and technical implementations. Model-based solutions may offer a possibility to cope withthe complexity of the necessary information, but a series of conflicts needs to be resolved especially for distributed modelingprojects. These conflicts create several difficulties when trying to generate ratios that can measure the quality of a service orservice candidate. This article presents an approach to generate ratios that are inherent to a service (candidate). Inherencemeans that the ratios are only dependent on the service and not on how the necessary information was modeled.
