The project Linked Data for Professional Education (LD4PE), funded between 2014 and 2017 by the Institute of Museum and Library Studies (IMLS) and lead by the University of Washington Information School, developed a web-based exploratorium to support structured discovery of online learning resources about Linked Data. The project produced this website, which has been converted into a static site for preservation, and a Linked Data Competency Index. DCMI will keep this site online on a "best effort" basis as long as resources permit. The Internet Archive's Wayback Machine should be regarded as the source of archival copies for the long term.

D2RQ: Accessing Relational Databases as Virtual RDF Graphs

The D2RQ Platform is an open-source 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 a database as Linked Data over the Web; Create custom dumps of a database in RDF formats for loading into an RDF store; Access information in a non-RDF database using the Apache Jena API.
