The mission of the RDB2RDF Working Group, part of the Semantic Web Activity, is to standardize languages for mapping relational data and relational database schemas into RDF and OWL. The two languages are the Direct Mapping (DM) and the RDB2RDF Mapping Language (R2RML).
The RDB2RDF Working Group Charter shows what the W3C has asked this working group to do.
Note: if you have an RDB2RDF implementation we would very much appreciate it if you would consider to submit test results for our implementation report.
This document surveys the current techniques, tools and applications for mapping between Relational Databases (RDB) and Resource Description Framework (RDF). Some knowledge of RDF as well as RDB concepts and technologies is assumed for readers of this document. The survey is intended to enable the members of the W3C RDB2RDF Incubator Group to: (1) collate the existing state of the art in mapping approaches between RDB and RDF, and (2) use the reference framework defined in this survey to effectively compare the different mapping approaches.
This document is the final report from the RDB2RDF XG. The XG recommends that the W3C initiate a WG to standardize a language for mapping Relational Database schemes into RDF and OWL.
These are documents produced outside the RDB2RDF Working Group that will be inputs to the standardization work of RDB2RDF WG. Please alert the co-Chairs or Staff Contact of the Working Group if you know of any material that you think merits inclusion.
These are deliverables that the group plans to produce, in line with the scope description above, but only if the time and the available manpower allows it. The Working Group will have to decide whether these documents will be published as Working Group Notes or additional Recommendations.
