Update "Convert: Keywords"

[BobSimons]

[This has been assigned to Harry Singh of ONC.]

ERDDAP has a Keywords converter which converts a CF Standard Name to/from a GCMD Science Keyword.
Unfortunately, the conversion file was made a long time based on CF Standard Names and GCMD keywords which are now out-of-date.
The project here is to update the conversion file (WEB-INF/classes/gov/noaa/pfel/erddap/util/CfToGcmd.txt).

Skills required: Understanding/familiarity with scientific terms

Difficulty: 2-4 weeks of work.

Mentor: Bob Simons (main author of ERDDAP)

Please also read the Programmer's Guide at https://coastwatch.pfeg.noaa.gov/erddap/download/setup.html#programmersGuide
especially the "Judging Your Code Contributions" section.

Hi @BobSimons ,

Tom, (https://github.com/thogar-computer) pointed us to this issue with GCMD and standard_name mappings.
In NVS we publish the cf_standard_names under the P07 vocabulary: http://vocab.nerc.ac.uk/collection/P07/current/
We also published the GCMD keywords as http://vocab.nerc.ac.uk/collection/P64/current/ but since the GCMD community started publishing them themselved we stopped following the versions. P64 is version 6.
There is a mapping already made between GCMD and standard_name but not for all of the terms.
Suggestions:
a.You can harvest these live, with a sparql query, as we have done in the past and I can share the sparql query.
b. We can host the mappings, if you already have them.

Our sparql endpoint lives here: http://vocab.nerc.ac.uk/sparql/
The query is the following:

PREFIX skos: http://www.w3.org/2004/02/skos/core#
select ?x ?prefLabelGCMD ?f ?p ?prefLabelStandard_name where{ http://vocab.nerc.ac.uk/collection/P64/current/ skos:member ?x.
?x ?f ?p.filter(regex(str(?p),"P07"))
?x skos:prefLabel ?prefLabelGCMD .
?p skos:prefLabel ?prefLabelStandard_name .

}

Thanks for the information, @alko-k. It's good to have another option.

For now, Harry Singh is working to update the mapping to the latest version of CF standard_names and GCMD Science Keywords (version 9.1).

Hello @BobSimons @alko-k can I take this issue?

[Pratikrocks]

and @BobSimons is there any platform where we can discuss about this project further...

[BobSimons]

@Pratikrocks, thanks for the offer, but, as the original posting of the issue says, this project has been assigned to Harry Singh. We're not doing it (so far) through GitHub, so the issue doesn't appear to be assigned to someone, but it has.
If for some reason Harry backs out (unlikely), then we can discuss you working on it.

@Pratikrocks and anyone: you can contact me via email if you want to discuss an ERDDAP issue privately: bob dot simons at noaa dot gov .

@Pritikrocks, how about picking one of the other projects?
