Version RTX-1.0 of umls2rdf
The original GitHub repo (https://github.com/ncbo/umls2rdf) doesn't have any releasees, and the RTX KG2 builder needs a consistently tagged release, I have forked the umls2rdf repo and tagged a "rtx-1.0" release. We do not want to be basing our continuous-integration production builds on the master branch of the ncbo/umls2rdf repo in case incompatible changes are introduced into the master branch.
Thanks to @msalvadores and all the developers of umls2rdf for providing this useful software.
