As Ed suggested, I was referring to D2RQ Platform [1]. It has a very simple 2-3 step process to publish existing relational databases as Linked Data with a SPARQL endpoint. 1) Download and unzip d2r-server [2] 2) Follow the Quick start to generate a mapping file for a relational database and start the server[3] 3) [Optional] Tweak the mapping file to switch names to other ontologies like FOAF, VCard, SKOS, etc. The mapping file is coded in Turtle/N3 and easy to manipulate. The vocabulary used to do the mapping fairly intuitive and well-documented [4]. It also has a SPARQL/Update extension [5] The mechanisms involved are simple, but peculiar to the D2RQ platform. Fortunately, the authors are working with the W3C to standardize the mechanisms.
