The RDB2RDF Working Group has published the First Public Working Draft of Use Cases and Requirements for Mapping Relational Databases to RDF. The need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document examines a set of use cases from science and industry, taking relational data and exposing it in patterns conforming to shared RDF schemata. These use cases expose a set of functional requirements for exposing relational data as RDF in the RDB2RDF Mapping Language (R2RML).

The W3C RDFa Working Group has published the First Public Working Draft of the RDFa API. RDFa API provides a mechanism that allows Web-based applications using documents containing RDFa markup to extract and utilize structured data in a way that is useful to developers. The specification details how a developer may extract, store and query structured data contained within one or more RDFa-enabled documents. The design of the system is modular and allows multiple pluggable extraction and storage mechanisms supporting not only RDFa, but also Microformats, Microdata, and other structured data formats.
