NMVW redirect does not work

[rschalkrce]

Thesaurus Nationaal Museum van Wereldculturen URI's are not displayed on the NMWV website when using 'Bekijk bij bron'.

E.g.: https://hdl.handle.net/20.500.11840/termmaster2670

Should probably be fixed by NWVW

Maybe related to the recent work on the NMVW collections @sdevalk or @GertjanFi?

Thanks! I'm not sure if this is related to the recent work on Wereldmuseum's collections, but I do know that the IRIs of terms in the NMVW thesaurus have been broken for several months now. By the look of things terms have been assigned new IRIs 😱. For example:

1. If I search for "pantserdoorborende granaten" in the Network of Terms [1], then the IRI "https://hdl.handle.net/20.500.11840/termmaster19066" is being returned. But the IRI resolves to an HTML page on the museum's website with the message "No results found for your query."

2. However, if I search for "pantserdoorborende granaten" in the museum's website [2], then two terms are being returned, including the term I'm looking for, "pantserdoorborende granaten". That term has the IRI "https://hdl.handle.net/20.500.11840/termmaster10067950". That IRI also resolves to an HTML page on the museum's website, but this time with the metadata of the term.

Note the difference between the IRIs: https://hdl.handle.net/20.500.11840/termmaster19066 versus https://hdl.handle.net/20.500.11840/termmaster10067950. The SPARQL endpoint on [3], unlike the SPARQL endpoint on the NDE data platform [4], contains the latest IRIs.

@sdevalk So should we switch to the https://data.colonialcollections.nl/nmvw/thesaurus endpoint in the Network of Terms? It’s always welcome to move away from the NDE Triply instance, which after all was intended to be a temporary solution. 😆

While that would resolve the issue for future searches, it doesn’t solve the problem where collections have linked to NMVW terms using their old IRIs. Is it possible to introduce a redirect from the old to the new IRIs on the NMVW side?

Note that the NoT currently uses https://data.netwerkdigitaalerfgoed.nl/NMVW/thesaurus/sparql, which looks older but equivalent; not https://data.netwerkdigitaalerfgoed.nl/NMVW/collectie, which is much larger. As an aside, can https://data.netwerkdigitaalerfgoed.nl/NMVW/collectie be phased out in favour of https://data.colonialcollections.nl/nmvw/collection-archives or is the latter a different dataset altogether?

@ddeboer Good questions! I cannot answer them, though: I am no longer involved in the Colonial Collections project. @GertjanFi Could you have a look?

[GertjanFi]

First of all @sdevalk you are as much not involved as I am not involved and you know that very well 😝

@ddeboer I am currently working with @sdevalk and @EnnoMeijers to phase out both the NMVW thesaurus and NMVW collectie in data.netwerkdigitaalerfgoed.nl and migrate to data.colonialcollections.nl the switch willen happen soon. I have contacted @rschalkrce today to ask him to update termennetwerk to the new instance.

I am aware there have been issues in the past with the IRIs but was under the conviction that had been solved. Since @sdevalk and myself are currently no longer involved with the project (development efforts have been concluded) I suggest we take a look together and see what the problem is and figure out a course to solve stuff (and find out who). I'll get back to this issue.
