SPARQL is a powerful language for working with RDF triples. However, SPARQL can also be difficult to work with, so much so that it often is not utilized anywhere near as often for its advanced capabilities, which include aggregating content, building URIs, and similar uses. This is the second piece in my exploration of OntoText’s GraphDB database, but many of these techniques can be applied with other triple stores as well.
Way back in 1991, Tim Berners-Lee, then a young English software developer working at CERN in Geneva, Switzerland, came up with an intriguing way of combining a communication protocol for retrieving content (HTTP) with a descriptive language for embedding such links into documents (HTML). Shortly thereafter, as more and more people began to create content on these new HTTP servers, it became necessary to be able to provide some kind of mechanism to find this content.
