Hi Vladimir, Thanks for the information! It is good to know what things still work. Does the reload on keystore change work with "Lets Encrypt!"? I've created JENA-2284 [1] to make sure the example gets updated. Fuseki/Main has a special support --https=CONF https certificate access detail

Re: Idiom for creating test instances of Node, Triple, etc?

There are the functions in SSE. e.g. Node SSE.parseNode(string) It has built-in prefixes so ":s" works. SSE.parseNode(":s") -> NodeFactory.createURI("http://example/s";); Triples are 3-tuples: "(:s :p :o)" or "(triple :s :p :o)" RDF-star supported SSE.parseNode("(qtriple :s :p :o)"); or <<>>

Yes, it's a good idea. TDB2 in Fuseki has the "compact" operation to do this without stopping the server. It creates a new "Data-/" directory and you can delete lower numbered databases. TDB1 - needs the server stopping for a rebuild. If you can stop updates, stop updates, 9server now re
