For various reasons I needed to look at SPARQL again. What’s the easiest way to put it up?, Here! I’ve been working with LH-Tools which is commented on at its authors site, and LH-RDF. I did not get this to finish satisfactorily, mainly based on my lack of SPARQL skills. May 2015
LH-Tools implements a SPARQL endpoint, and LH-RDF implements a series of alternative RDF schemas. LH-RDF has been deactivated at the moment, but the SPARQL query screen is here; it uses the default rdf feed as a source.
I have errors occurring when using LH-RDF; see the comments to track. Jan 2017
