Abstract:
The W3C RDB2RDF working group proposed R2RML as a standard mapping language that defines how to
publish data stored in relational databases as RDF triples. However, R2RML mappings are sometimes difficult
to understand, which may affect the users’ understanding of the transformations the original data suffer
until published as RDF triples. To address this problem, this paper extends a semi-automatic method to define
R2RML mappings to include design rational, thereby helping publishers to document the design process and
final users to consume the published data. The paper also proposes to use the design rationale captured to
enrich the representation of the original data in RDF, which ontology matching algorithms may use to find
potential links to other existing vocabularies, thereby promoting interoperability.
