R2BA - Rationalizing R2RML Mapping by Assertion
Rita Cristina Galarraga Berardi, Vânia Maria Ponte Vidal, Marco A. Casanova · 2015
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. 1
