Establishing flexible, data source and structure independent interoperability between databases, web services or devices is an ubiquitous problem in today’s digitized, connected world. The concept of semantic interoperability is a promising approach to abstract communication from concrete protocols and data structures to a more meaning driven data representation. While transforming structured data into semantic knowledge graphs is a well investigated problem, actually using semantic data in an ecosystem of established legacy services, often providing only a standard structured data API, is still an open issue. In this paper we propose an approach on how to formally describe possible mappings between a higher level semantic data representation onto syntactically fixed structured data objects, introduce an algorithm describing how to generate structured data objects from semantic input using mapping rules following these concepts, and illustrate the approach with an example implementation for a possible interoperability layer service, connecting a semantic input data set to a JSON API.
