Notation for deprecation in SKOS export

[cessda-bitbucket-importer]

Original report on BitBucket by Taina Jääskeläinen.

Best start working on this only after Oliver has made his changes and there are code level URIs/identifiers.

‌

When amending the SKOS export, taking a look at ELSST Thesaurus SKOS/RDF, noticed the following notations for deprecation and replacement which may help:

‌

1. ENVIRONMENTAL DEGRADATION (deprecated term)

   1. URI https://elsst.cessda.eu/id/3/bfde4f9b-6466-4c39-8680-39218dbb3580

2. ENVIRONMENTAL CHANGES (the replacing term)

   1. https://elsst.cessda.eu/id/3/5a40a735-1eca-4afa-930c-0b131f06e8af

‌

SKOS for ENVIRONMENTAL DEGRADATION (deprecated term) has:

dc:isReplacedBy
<skos:Concept rdf:about="https://elsst.cessda.eu/id/3/5a40a735-1eca-4afa-930c-0b131f06e8af">

Thanks, this helps, I’ll check the SKOS export in CVS.

Regarding the descriptive terms(=prefLabels) of the deprecated code in different languages,
this is the case of how a single concept is presented to the user as an RDF object. This can be
different from a vocabulary RDF representation. There might be for convenience additional
information inferred when exporting some portions of the vocabulary.

Both RDF examples of the concepts above contain such additional information that was inferred
from the RDF representation of the vocabulary. If you look at the RDF representation of the ELSST vocabulary
and search for the first concept (https://elsst.cessda.eu/id/3/bfde4f9b-6466-4c39-8680-39218dbb3580),
this information is missing, but it is implicitly there and can be inferred through dct:isReplacedBy

added RDF representation of concept deprecation:

• owl:deprecated
• dcterms:isReplacedBy
• dcterms:replaces (inverse relation to dcterms:isReplacedBy)

The other RDF elements should be in accordance to some schema for exporting vocabularies in SKOS/RDF. There's something in #387, but the stuff for deprecation in not specified there. I would rather stick to a clear schema when adding additional elements to RDF, so I'm closing this issue.

I’ve asked Darren to add info for deprecation in RDF either here or into the attached schema in #387.

Darren, could you please add to the ModeOfCollection-1.0.1.rdf document that is attached here an example where the concept SelfAdministeredQuestionnaire is deprecated in the next version.

I think we will go with the deprecation information added by Stefan for now. I will close this issue and put the information that we would need a clear schema for adding additional elements to RDF to the issue #387.

@‌Oliver Hopt As agreed, Oliver will add ‘Valid to’ information for deprecated terms to SKOS/RDF.

Valid from - also related to #431.

[MajaDolinar]

@OliverHopt could you please add this "Valid to" information for deprecated terms to SKOS/RDF? Please give an update on where we are with this
