As a user I want to process the graph of Wikidata classes (entities with P279 statements), or a subgraph of it, in order to study Wikidata's structure and get relevant insights without having to download the entire dump of entities.

Problem: Full Wikidata dumps are too big to be processed, sometimes even too big to be downloaded. When we just need to study classes, that is, how Wikidata's knowledge is organized, having a specific dump with only classes (so much smaller) would be valuable. Books, scholarly publications and other heavy sets of entities would be, obviously, excluded from this dump.
