NVS P06 units that are missing from QUDT

[dr-shorthair]

This list attached here https://github.com/qudt/qudt-public-repo/issues/268#issuecomment-721424132 shows items from the NERC Vocabulary Service P06 vocabulary which do not have matches in QUDT, but could do since the elements are already there:

Here they are with Dimension vectors and conversion-multipliers

@gwemon Progress!

[dr-shorthair]

@steveraysteveray I think this is minimum info needed for some new Units ?

1. a little unsure about some of the dimension vectors that involve dimensionless quanties
2. I did the conversions as multipliers, but in some cases (mostly around time) it might be better to use coefficients?

What is the best way to progress these? I didn't want to make each one a separate issue/PR - that would be ridiculous. Note that these units are all currently in-use in oceanography datasets, so even though some of them look a bit strange and sometimes redundant, they are needed.

And now with Labels and Definitions taken directly from P06. I've added some QuantityKind entries, but many not available.

Updated to fix misunderstanding of D value in Dimension Vector - #270 qudt-requests.xlsx (see below)

Simon, Once we're less distracted with the future of democracy over here, I will be focusing on all your hard work so that we can add these units, and come to some agreement on the quantity/quantitykind question!

[dr-shorthair]

Added a couple more: qudt-requests.xlsx (see below)

For sure I did not expect these to be processed immediately. Just trying to make it as easy as possible for us to knit together the various systems ;-)

FYI recent additions to NVS P06 have added link to QUDT as a matter of course - https://github.com/nvs-vocabs/P06/issues/19 http://vocab.nerc.ac.uk/collection/P06/current/MGRM/

[steveraysteveray]

Wonderful!

[dr-shorthair]

A few corrections qudt-requests.xlsx (see below)

[steveraysteveray]

Simon, I did some hacking to bludgeon your spreadsheet above into triples that conform to our structure. 😄 However, along the way I see a few suspicious entries, such as BQ-SEC-PER-M3 having a QuantityKind of ActivityConcentration, since all the other units with that QuantityKind have a different dimensionality:

So I invite you to take a look at the srr-P06-imports branch and let's quality-check it. Also, as you know from your spreadsheet, many of the units are missing QuantityKind values altogether.

[dr-shorthair]

The QuantityKind column is very dubious throughout. I just threw a few in where I thought I could find existing QKs that fit, but needs to be reviewed. Probably we should bring in @gwemon

That one is definitely incorrect - looks like it was mis-pasted and should be in the line above. Probably it should be AbsoluteActivity

I'll have a look later on this week.

[dr-shorthair]

Suggest just working from the spreadsheet.

[dr-shorthair]

@steveraysteveray I converted the spreadsheet to SKOS-Play! format which makes it easy to generate TTL (not actually restricted to SKOS)-

Excel file - P06-additions-to-QUDT.xlsx

TTL file - P06-additions-to-QUDT.ttl

[dr-shorthair]

Files also in this fork https://github.com/dr-shorthair/qudt-public-repo/tree/P06/community/NVS-P06

This SKOS-Play! format seems pretty easy to work with. Might be a good general submission template?

[steveraysteveray]

Very interesting! About a week ago I discovered SHACL-Play, from the same people. https://shacl-play.sparna.fr/ I'll check out SKOS-Play.

[dr-shorthair]

Maybe not so much 'bludgeoning' required ;-)
