So I made some changes to allow loadRDF to take in a custom ValueFactory so that I can have shorter strings, for example: "http://example.com/rel"; -> "ex:rel"
but now I still get similar errors now when adding edges. It works if the label has a period, so now I use: "ex:.rel". *Why does OrientDB URL encode edge names if it's going to complain about them later? Is there a bug report for this?* On Thursday, 15 May 2014 21:03:00 UTC-4, Justin Harris wrote: > > I think I found some things to help me out.
