Embodiments may include a system for generating an enhancement of an ontology. The system may have a memory unit and a processing unit. The memory unit may be configured to provide the ontology and to store the ontology with the enhancement. The processing unit may be configured to identify a service specification, such as a service product or a contract, that may be represented by a class of the ontology. The service specification may describe a capability of a service. The processing unit may be further configured to compute a set of instances that are specified by the service specification and by a requirement specification and to enhance the ontology with a generated class representing the set of instances in case that the set of instances has one or more instances.
