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.

SPARQL Tutorial: Datasets

This tutorial covers RDF Datasets- the units that are queried by a SPARQL query. An RDF Dataset consists of a default graph, and a number of named graphs. Discusses the use of the GRAPH keyword; querying to find data from graphs that match a pattern (the name of the graphs to be queried can be determined with the query itself); how to describe RDF Datasets using FROM and FROM NAMED.
