As of today 130 P06 units have been aligned to QUDT units.

dr-shorthair commented 3 years ago

You might also add requests for the 'missing' units in QUDT as issues. e.g. https://github.com/qudt/qudt-public-repo/issues/221

If QUDT had the complete set, would there be potential to retire P06? else retain it in order to capture the links to the other NVS vocabs.

dr-shorthair commented 3 years ago

FWIW I've created a SWEET-QUDT alignment graph - see https://github.com/ESIPFed/sweet/pull/221

dr-shorthair commented 3 years ago

And also catalogued the ones from SWEET that are missing from QUDT - https://github.com/qudt/qudt-public-repo/issues/231

@dr-shorthair No I don't think so. P06 is part of a number of well established data workflows and file formats, and it would be more effort to retire it than it is to maintain it. I see QUDT as being a useful external reference for us and also, hopefully, a source of community developed tools.

dr-shorthair commented 3 years ago

Fair enough. That was what I expected. But I think we can make the alignment closer.

Yes I completely agree. This was a starter. I'll try and contribute more as soon as I have a bit more time to do so.

@gwemon I will assist with this.

I believe this is the list that does not (yet) have QUDT matches, with notional QUDT identifiers inferred: P06-qudt-missing-ucum.txt

  1. the ones tagged --- cannot be matched
  2. the ones tagged *** already exist in the QUDT vocabulary
  3. all the others need to be added to QUDT.
dr-shorthair commented 3 years ago

So these seven can be matched to units that already exist in the QUDT vocabulary:

The first 2 QUDT URLs http://qudt.org/vocab/unit/M2-PER-SEC2 and http://qudt.org/vocab/unit/CentiM2-PER-SEC are not found. I have added the remaining 5 to the NVS. They will be live shortly after 0200UT.

dr-shorthair commented 3 years ago

OK - I've added them to the spreadsheet here https://github.com/qudt/qudt-public-repo/issues/268#issuecomment-721424132

They are all OK now

Mappings added to https://vocab.nerc.ac.uk/collection/P06/current/UCMS and http://vocab.nerc.ac.uk/collection/P06/current/SQM2 It will be live on the NVS shortly after 0700 UT tomorrow morning
