Re: Established vocabularies for units in RDF?

Greetings.

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).

All the best,

Norman
