The rising popularity of RESTful Web services has recently motivated the extension of existing service orchestration engines to support the composition of services that do not rely on machine-readable descriptions. At the same time, within the Linking Open Data initiative, data sets are published conforming to the Linked Data principles, which can be naturally achieved by exposing RDF data through RESTful interfaces. In this position paper, we motivate the use 'of service orchestration to define workflows for interlinking open data. We introduce the design of an abstract workflow for the semantic enrichment of such data with the purpose of providing an integrated view on otherwise isolated data sources. Finally, based on this abstract workflow we present early work on a concrete implementation and report on our experiences.
