Dear all

From Euro-VO Registry, we'd also be happy to get rid of RI 1.0 as this is causing us from maintenance issues and we're not sure that's actually being use by real users 😉.

Thanks in advance

Cheers

As the primary STScI registry maintainer, I would love to see this discussed!

I am hoping to participate in the session remotely, and am grateful to other MAST folks who should be in attendance and can also speak to the issue.

In short, though, yes, please, let's get rid of the RI 1.0 search.
None of the STScI search pages or higher-level APIs use it internally: they are either based on our RegTAP implementation, or on a SOLR index built directly from our OAI-PMH interface. The STScI archive has a medium-term plan to retire the Microsoft IIS web service systems it runs on along with most of our other registry infrastructure, and every old piece we don't have to port to something new would personally brighten my day.

I also believe there are no longer other search registries offering it beyond us and Euro-VO.

Cheers!

a discussion topic I'd like to suggest for the Registry session in Bologna is possible retirement of Registry Interface 1.0 full searchable registry services. RI1.0 has been effectively deprecated for this purpose in favour of RegTAP since about 2014.

As far as I know there are only two such services running, Euro-VO and STSci (there used to be an astrogrid service too but I think it's long gone). Both of these sites also offer RegTAP interfaces to the same information, which are as far as I know preferable in all respects. Henrik Norman tells me that the logs show no recent accesses to the RI1.0 searchable interface at Euro-VO (I haven't asked about STSci).

Topcat offers the option of querying using RI 1.0 as an alternative to RegTAP, but I don't know why anybody would want to.
I see some failures (I don't know if they are client or service issues) when topcat tries to make certain RI 1.0 queries to both the Euro-VO and STSci services. I could try to track them down and either make fixes myself or ask the service providers to do so ... but is it worth it?

If those two sites retire their RI1.0 interfaces, and clients such as topcat remove any capability for querying using RI1.0, we could wave goodbye to RI1.0 and reduce the maintenance burden on the services at Euro-VO and STSci and on clients like TOPCAT.

Questions:
- is it safe/advisable for TOPCAT to remove the RI1.0 client functionality?
- are there other clients using RI1.0 services?
- is anybody using Euro-VO or STSci RI1.0 services?
- if so, are they actually working properly?
- would those service operators like to retire these services?
- are there any other RI1.0 searchable registries out there?

Thanks,

Mark
