Greetings. Paul Houle asked: >>> I am wondering today what is the state of the art in terms of >>> representing >>> measurement units in RDF. As Simon Cox mentioned, QUDT <http://qudt.org> is very mature. It's comprehensive and thoughtful, and the authors are fully aware of the various subtleties which can crop up with units. That it's associated with both TopQuadrant and NASA is a recommendation. The current version is 1.1, the site says 'Release 2 of QUDT is being published incrementally.', and the last update to that page was in August 2016. There already seems to be worryingly many units ontologies (ie, more than one). QUDT has worked for me (I've used it for a project <https://bitbucket.org/nxg/unity> concerned with parsing unit strings).
