In this blog post, the author proposes that DBpedia may be the best source of reusable URIs when one is seeking to describe entities in Linked Open Data. He shares a script for a SPARQL query that selects preferred and alternative labels for a group of DBpedia entries at once. Taking this a step further and adding a few SKOS properties to the mix, a single query can pull data from DBpedia to populate a SKOS-based thesaurus with preferred and alternative labels.

- Knows Simple Knowledge Organization System, or SKOS (2009), an RDF vocabulary for expressing concepts that are labeled in natural languages, organized into informal hierarchies, and aggregated into co
- Knows the "five stars" of Open Data: put data on the Web, preferably in a structured and preferably non-proprietary format, using URIs to name things, and link to other data.
- Uses CONSTRUCT to extract and transform results into a single RDF graph specified by a graph template.
