Require IRI nodeKind on configuration:itemObject

[forest-savage1234]

This Pull Request is a bug-fix change proposal, believed to be of low risk to the ontology and its downstream resources.

configuration:ConfigurationEntry currently lets itemObject be a blank node (sh:BlankNodeOrIRI). The range is core:UcoObject, which must be IRI-identified. The shape becomes sh:IRI.

configurationEntry and dependencies stay sh:BlankNodeOrIRI. The sh:xone itemObject vs itemValue split is untouched.

Closes #663.

Out of scope

• UCO Typo in analysis.ttl? #694 / uco-core:Compilation should upstream an in-common sh:PropertyShape for uco-core:object #662
• Other BlankNodeOrIRI shapes on Configuration (configurationEntry, dependencies)
• The sh:xone itemObject vs itemValue split
• New terms

One token. Alex named this shape in #663. I am a volunteer; if blank-node objects are intentional, I will stand down.

Validation

• make check (UCO CI)
• make --directory ontology/uco/configuration --file ../../../src/review.mk check

Boxes match commands actually run after the one token.

Box run 2026-08-22 11:19–11:36 PM AKDT on /workspace/checkouts/UCO develop 586ac690d9c9ca02ad3b9d94faf0b0a9dc91a615 (586ac69 Merge pull request #688 from ucoProject/release-1.5.0). Working tree at run time: one token in ontology/uco/configuration/configuration.ttl only (itemObject BlankNodeOrIRI → IRI). analysis.ttl was reset to HEAD so this is not bundled with #694. Catalogs not in this packet. Python 3.13.5.

A first make check started on this same tree at 11:21 PM AKDT exited 2 (rm: cannot remove '__uco_monolithic.ttl': No such file or directory / Makefile:104) because it raced another make check in the same checkout. That failed run is not the checked box. The checked make check is the completed independent run below (started 11:19 PM AKDT, EXIT:0, elapsed 1003192 ms, ended 2026-08-23T07:36:34Z = 11:36 PM AKDT).

I am a volunteer. Thank you for the time. I am trying to become more useful on this work, so I welcome a critical look. If this is the wrong cut, or you want me to stand down, say so and I will recut from notes, or close it.

Thank you for the time on this review. This only requires IRI nodeKind on configuration:itemObject. If that is the wrong cut, say so and I will recut from notes.
