Alban, I think having an installable schema for units of measure with definitions and functions would be a great addition to PostgreSQL. I for one know we would use it in GNUmed (wiki.gnumed.de). A few points: Would these guys be of use as a source for reference data ? http://unitsofmeasure.org/ You may want to think about whether there's use in combining units with tagged types: http://svana.org/kleptog/pgsql/taggedtypes.html There's also a Debian package which comes with a text format units database: http://packages.debian.org/source/sid/units The original source for that: This package was put together by me, James Troup <james@xxxxxxxxxx>, from the GNU sources, which I obtained from sunsite.doc.ic.ac.uk:/pub/gnu/units-1.54.tar.gz. The current version of the package was obtained from ftp://ftp.gnu.org/gnu/units by John Hasler, the current Debian maintainer. > I think this database is fairly usable in its current state. Any more > development on it Yes please ! :-) > warrants its own project page somewhere and taking > it off-list, I'll no longer pester you with updates on this ;) Ah, no problem. Please keep posting release announcements. Maybe on -announce if so.
