One of the first knowledge graphs (KG) that we at DataFabric built (and continue to evolve) was the knowledge graph of Federal Tax Service of Russian Federation (FTS) which accumulates tremendous amount of data about Russian companies and individuals. In this story I dive into the details of the steps we took and what we continue to do to maintain the knowledge graph.

We at DataFabric help companies build knowledge graphs on top of their existing data to facilitate better access through unified interfaces, reusability, data enrichment and as a result better analytics and automation. And as in case of any relatively new and complex technology, it’s important to understand and exploit the same terms (a.k.a. names) for things.

I believe, converting bunch of CSV, JSON or XML files to an RDF format is a very popular task for people dealing with Semantic Web, Linked Data, RDF and such stuff. However, I can’t easily name a ready-to-use converter that I’d recommend, so I’ve decided to review some of them to use the most suitable one next time.
