Core Subject thesaurus dates

[ianwallen]

This issue is to discuss and resolve the Core Subject thesaurus dates

We are looking to update
https://github.com/metadata101/iso19139.ca.HNAP/blob/3.12.x/src/main/config/codelist/local/thesauri/theme/GC_Core_Subject.rdf
so that it has the correct dated by setting the dcterms:issued and dcterms:created

Most of the records from FGP contain the following for Core Subject Thesaurus

              <gmd:thesaurusName>
                  <gmd:CI_Citation>
                     <gmd:title xsi:type="gmd:PT_FreeText_PropertyType">

                                               codeListValue="RI_409">custodian; conservateur</gmd:CI_RoleCode>

                  </gmd:CI_Citation>
               </gmd:thesaurusName>

Based on that information would add the following to the Core Subject Thesaurus.

      <dcterms:issued>2004</dcterms:issued>
      <dcterms:created>2016-07-04</dcterms:created>

However after looking at the source, I don't quite understand these values.

Background
https://canada.multites.net/cst/def.asp?lang=En&n=A8144381-1
Change History
https://canada.multites.net/cst/def.asp?lang=En&n=B1B9013A-1

Based on this information it seems like the <dcterms:created> of the core subject thesaurus should be 2001

In 2001, various projects for indexing information resources of the Government of Canada lead to the creation of the CST

Also based on https://canada.multites.net/cst/def.asp?lang=En&n=B1B9013A-1 there is no date related to 2016-07-04 so not sure if that should be 2017 or 2016-06? Or it is possible that we are using a more recent version? Maybe we should simply update the thesaurus to the most recent version and set the dcterms:issued to that value.

Would like to get some input related to the dates that should be used in the thesaurus.

I would like input from @bo-lu, @jodygarnett, @josegar74 on this issue.

Looks like we are currently using version 2020-11
