  In order to react efficiently to changes in production, resources and their
functions must be integrated into plants in accordance with the plug and
produce principle. In this context, research on so-called capabilities and
skills has shown promise. However, there are currently two incompatible
approaches to modeling capabilities and skills. On the one hand, formal
descriptions using ontologies have been developed. On the other hand, there are
efforts to standardize submodels of the Asset Administration Shell (AAS) for
this purpose. In this paper, we present ongoing research to connect these two
incompatible modeling approaches. Both models are analyzed to identify
comparable as well as dissimilar model elements. Subsequently, we present a
concept for a bidirectional mapping between AAS submodels and a capability and
skill ontology. For this purpose, two unidirectional, declarative mappings are
applied that implement transformations from one modeling approach to the other
- and vice versa.
