Below is part one of a small series on ctj rdf, a new program I made to transform ContentMine CProjects into SPARQL-queryable Wikidata-linked rdf. ctj has been around for longer, and started as a way to learn my way into the ContentMine pipeline of tools, but turned out to uncover a lot of possibilities in further processing the output of this pipeline (1, 2). The recent addition of ctj rdf expands on this.
