Hi Vladimir! It's great to hear that you're interested in iur tools! Quick replies to your questions: The largest vocabs we analyzed using both qSKOS ans Skosify were over 1GB (IIRC RAMEAU was 1,5GB) so they should work. Naturally you must install locally. It might take an hour or two and a few GB of RAM (8 should be enough with Skosify, if you install rdflib 4.x). As for the extensions, you'll have to try what happens. Most vocabs we analyzed had some custom extensions. Skosify supports all input formats that rdflib can parse, so e.g. rdf/xml, turtle, n-triples should all work. But you may hit parser bugs in some cases - if that happens you can reserialize with Jena rdfcat or rapper from Redland. I'm very interested to hear about your results!
