Abstract:
Translating data from linked data sources to the vocabulary that is expected by a linked data application
requires a large number of mappings and can require a lot of structural transformations as well as complex
property value transformations. The R2R mapping language is a language based on SPARQL for publishing
expressive mappings on the web. However, the specification of R2R mappings is not an easy task. This paper
therefore proposes the use of mapping patterns to semi-automatically generate R2R mappings between RDF
vocabularies. In this paper, we first specify a mapping language with a high level of abstraction to transform
data from a source ontology to a target ontology vocabulary. Second, we introduce the proposed mapping
patterns. Finally, we present a method to semi-automatically generate R2R mappings using the mapping
patterns.
