Getting Into Linked Data and the Semantic Web This is a post about the RDF metadata model and SPARQL query language, two components of the Linked Data structured data methodology. All of this is part of the collective vision known as the Semantic Web–a Web of Data that can be consumed by both humans and machines alike. The Lay of Linked Data I walked through the index forests, simply upon a lark A
This started out as an answer at Semantic Overflow on how RDF database systems differ from other currently available NoSQL solutions. I've here expanded the answer somewhat and added some general-audience context. RDF database systems are the only standardized NoSQL solutions available at the moment, being built on a simple, uniform data model and a powerful, declarative query language. These syst
The D2RQ Platform is a system for accessing relational databases as virtual, read-only RDF graphs. It offers RDF-based access to the content of relational databases without having to replicate it into an RDF store. Using D2RQ you can: query a non-RDF database using SPARQL access the content of the database as Linked Data over the Web create custom dumps of the database in RDF formats for loading i

D2R Server: Accessing databases with SPARQL and as Linked Data D2R Server is a tool for publishing relational databases on the Semantic Web. It enables RDF and HTML browsers to navigate the content of the database, and allows querying the database using the SPARQL query language. It is part of the D2RQ Platform. 1. About D2R Server 2.
