From e8c1a596031aa06bf3d695bf7e6ab74012ae25d0 Mon Sep 17 00:00:00 2001 From: Your Date: Mon, 15 Jun 2026 14:03:14 +0200 Subject: [PATCH 1/2] =?UTF-8?q?fix(ontology):=20#204=20OwlAdapter=20reader?= =?UTF-8?q?s=20=E2=80=94=20RDFResource.ToString()=20+=20SKOSHelper=20silen?= =?UTF-8?q?t-empty=20fallback?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes the bug surfaced by PR #480 (OwlAdapter readers returning empty). Root cause was deeper than the .URI type-mismatch: RDFResource.Equals uses runtime-type comparison (GetType()), so even RDFResource.Equals(fresh RDFResource) is false when the stored IRI is a subtype — only GetIRI().Equals works. Switched all 14 reader comparison sites to .ToString() equality (the URI-as-string basis the write-path tests already proved correct, agnostic to RDFResource subtype). Also completes the "incomplete SKOSHelper bypass" flagged on the dashboard: CheckIsNarrowerConcept / GetExactMatch/Close/RelatedMatch had try/catch fallbacks that only triggered on exception, but SKOSHelper returns false/empty SILENTLY — so the (now-correct) fallback scanner was never reached. Changed fallback to trigger on empty/false result too, not just exception. Tests: section-(A) [BUG] characterization suite from #480 flipped to proper round-trip assertions (now the regression suite for this fix). Full suite 218 pass / 0 fail / 5 skip (baseline preserved). Production impact: Tests/OwlOntologyValidationTests.cs (post-gen OWL validator, not xUnit) was silently false-passing "no concepts → skip → PASS" on annotation and AIF checks because GetResourcesByType(Concept) returned empty. Now resolves correctly → validation becomes reliable (unblocks trustworthy #133 OWL publication).
