All metadata validations fail with `src-resolve: Cannot resolve gco:AbstractObject_Type` after schemas.isotc211.org redesign on 2026-05-05

Hello,

Since the ISO/TC 211 schema host (schemas.isotc211.org) was redesigned on 2026-05-05, every dataset/service metadata validation against the bundled INSPIRE Reference Validator fails at XSD load time with:
'Validation failed: http://schemas.opengis.net/iso/19139/20070417/srv/1.0/serviceMetadata.xsd, 33:49: src-resolve: Cannot resolve the name 'gco:AbstractObject_Type' to a(n) 'type definition' component.'
I tried images 2025.1.1, 2024.3 and 2026.1

I cannot really do a workaround because the validator ignores the document's xsi:schemaLocation and likely uses its own bundled chain.

I also opened an issue at ISO-TC211 asking them to put a redirect from their old path to the new.

If there is something else that I could do, please let me know.

Thank you.

@constantinlazar apologies for the problem -- it's now resolved:

https://schemas.isotc211.org/19139/-/gco/1.0/gco.xsd

https://schemas.isotc211.org/19139/-/gmd/1.0/gmd.xsd

Thanks for reporting!

Thank you @ronaldtse for the prompt response and solution!
I still think that the INSPIRE Reference Validator should not use an internal chain to get these, but maybe it's too big of a change.
I'm closing the issue.
