Here is a sample 12-concept scheme for the IT Incident Management Taxonomy, structured in the plain-labeled format the validator expects. I'll generate it, then immediately run the full validation — and I've deliberately seeded a few realistic errors so the validator has something to find. --- ``` CONCEPT: Incident prefLabel: Incident altLabel: IT Incident definition: An unplanned interruption to an IT service or reduction in quality. | Evidence: ITIL v4 Service Management broader: top concept narrower: Major Incident, Recurring Incident related: Problem, Change Request notation: INC CONCEPT: Major Incident prefLabel: Major Incident altLabel: P1 Incident definition: An incident with significant business impact requiring expedited resolution. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Escalation, SLA Breach notation: INC-MAJ CONCEPT: Recurring Incident prefLabel: Recurring Incident altLabel: Repeat Incident definition: An incident that has occurred more than once with the same root cause. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Problem notation: INC-REC CONCEPT: Problem prefLabel: Problem altLabel: Root Cause Issue definition: The underlying cause of one or more incidents. | Evidence: ITIL v4 Service Management broader: top concept narrower: Known Error related: Incident, Change Request notation: PRB CONCEPT: Known Error prefLabel: Known Error altLabel: none definition: A problem with a documented root cause and a workaround. | Evidence: IT service desk email corpus broader: Problem narrower: none related: Resolution notation: PRB-KE CONCEPT: Change Request prefLabel: Change Request altLabel: RFC, Request for Change definition: A formal proposal to alter an IT service or infrastructure component. | Evidence: IT service desk email corpus broader: top concept narrower: none related: Incident, Problem notation: CHG CONCEPT: Priority prefLabel: Priority altLabel: Incident Priority definition: A classification of urgency and impact used to sequence incident handling. | Evidence: IT service desk email corpus broader: Category narrower: none related: SLA Breach, Escalation notation: PRI CONCEPT: Category prefLabel: Category altLabel: Incident Category definition: A grouping used to classify incidents by type or affected service area. | Evidence: IT service desk email corpus broader: top concept narrower: Priority related: none notation: CAT CONCEPT: Escalation prefLabel: Escalation altLabel: Ticket Escalation definition: The process of raising an incident to a higher support tier or management level. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Major Incident, SLA Breach, Priority notation: ESC CONCEPT: SLA Breach prefLabel: SLA Breach altLabel: SLA Violation definition: An event in which a service level agreement target has not been met. | Evidence: IT service desk email corpus broader: SLA Breach narrower: none related: Major Incident, Escalation, Priority notation: SLA-B CONCEPT: Resolution prefLabel: Resolution altLabel: Incident Resolution definition: The action or set of actions that restores normal service operation. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Known Error, Resolution notation: RES CONCEPT: Service Request prefLabel: Service Request altLabel: none definition: A formal user request for something new — access, information, or a standard change. | Evidence: IT service desk email corpus broader: none narrower: none related: Change Request notation: SRQ ``` --- Now running full validation. --- # CONCEPT SCHEME VALIDATOR™ v1.1 **Pre-flight check:** `{CONCEPT_SCHEME}` — 12 concepts present with labels and relationships. ✓ **`{SCHEME_NAME}`** — "IT Incident Management Taxonomy" — present and non-placeholder. ✓ No HALT or FLAG conditions triggered. Proceeding to Section 1. --- ## SECTION 1 — SCHEME PROFILE ``` SCHEME NAME: IT Incident Management Taxonomy CONCEPT COUNT: 12 TOP CONCEPTS: Incident, Problem, Change Request, Category (declared broader: top concept) MAX DEPTH: 3 levels (Category → Priority → [none]; Incident → Major Incident / Recurring Incident / Escalation / Resolution; Problem → Known Error) PROPERTIES USED: prefLabel | altLabel | definition | broader | narrower | related | notation INPUT FORMAT: plain-labeled ``` --- ## SECTION 2 — INTEGRITY CHECK RESULTS --- ``` CHECK 1 — SELF-REFERENCE STATUS: FAIL SEVERITY: CRITICAL Violation: SLA Breach declares broader: SLA Breach — a concept naming itself as its own broader concept. Resolution declares related: Resolution — a concept naming itself in its own related list. Evidence: CONCEPT: SLA Breach broader: SLA Breach ← self-reference in broader CONCEPT: Resolution related: Known Error, Resolution ← self-reference in related Corrected entries: see Section 3. ``` --- ``` CHECK 2 — BROADER/NARROWER CYCLES STATUS: FAIL SEVERITY: CRITICAL Violation: A hierarchy cycle exists between Category and Priority. — Category declares narrower: Priority — Priority declares broader: Category This is consistent so far, but: — Category declares broader: top concept — Priority declares related: Escalation, SLA Breach Re-examining for a cycle: tracing Priority's broader chain: Priority → broader: Category → broader: top concept No return to Priority. That path is clean. Now check SLA Breach's broader chain: SLA Breach → broader: SLA Breach → broader: SLA Breach → … (infinite — self-reference loop) The self-reference in Check 1 also constitutes a degenerate cycle. Reported here as a cycle; the self-reference is the proximate cause. Full cycle path: SLA Breach → broader: SLA Breach → broader: SLA Breach (infinite loop — degenerate self-referential cycle) Corrected entry: see Section 3 (same fix as Check 1 for SLA Breach — remove the self-referential broader). ``` --- ``` CHECK 3 — ORPHAN CONCEPTS STATUS: FAIL SEVERITY: HIGH Violation: Service Request has no broader relationship and no topConceptOf declaration. It is an unanchored concept floating outside the hierarchy. Evidence: CONCEPT: Service Request broader: none narrower: none (no topConceptOf declared) Corrected entry: see Section 3. ``` --- ``` CHECK 4 — DUPLICATE PREFERRED LABELS STATUS: PASS Evidence: All 12 prefLabels are unique. No two concepts share the same preferred label under case-insensitive comparison. ``` --- ``` CHECK 5 — MISSING PREFERRED LABEL STATUS: PASS Evidence: All 12 concepts carry exactly one prefLabel. No concept entry is missing a prefLabel field. ``` --- ``` CHECK 6 — PREFERRED LABEL = ALTERNATIVE LABEL COLLISION STATUS: PASS Evidence: No concept has a prefLabel value that also appears in its own altLabel list. (Note: Known Error and Service Request have altLabel: none — treated as no altLabel declared.) ``` --- ``` CHECK 7 — BROADER + RELATED REDUNDANCY STATUS: FAIL SEVERITY: MEDIUM Violation: Escalation declares broader: Incident AND related: Major Incident. Major Incident itself declares broader: Incident. Escalation and Major Incident are siblings — this is not a broader+related redundancy on the same target. Re-examining all concepts for the exact condition (broader: X AND related: X on the same concept): — Incident: broader: top concept; related: Problem, Change Request → no match — Major Incident: broader: Incident; related: Escalation, SLA Breach → no match — Escalation: broader: Incident; related: Major Incident, SLA Breach, Priority → Incident not in related → no match — Resolution: broader: Incident; related: Known Error, Resolution → self-reference already caught in Check 1; Incident not in related → no match — Priority: broader: Category; related: SLA Breach, Escalation → no match — SLA Breach: broader: SLA Breach (self-ref, caught); related: Major Incident, Escalation, Priority → SLA Breach not in related → no match STATUS: PASS Evidence: No concept declares both broader: X and related: X for the same target X. The broader+related redundancy condition is not present in this scheme. ``` *(Status corrected to PASS after full trace — initial violation note was not confirmed by evidence.)* --- ``` CHECK 8 — DANGLING REFERENCES STATUS: FAIL SEVERITY: HIGH (MISSING CONCEPT sub-case) Sub-case A — MISSING CONCEPT: No referenced concept is entirely absent from the scheme. All labels appearing in broader/narrower/related fields (Incident, Problem, Change Request, Category, Major Incident, Recurring Incident, Known Error, Priority, Escalation, SLA Breach, Resolution, Service Request) are defined entries. ✓ Sub-case B — INVERTED REFERENCE: Violation 1: Incident declares narrower: Major Incident, Recurring Incident. Confirmed — both declare broader: Incident. ✓ Violation 2: Incident does NOT declare narrower: Escalation or Resolution, yet both declare broader: Incident. The narrower list for Incident is incomplete — it omits Escalation and Resolution, which are children by their own broader declarations. Evidence: CONCEPT: Incident narrower: Major Incident, Recurring Incident (Escalation and Resolution both declare broader: Incident but are absent from this narrower list) CONCEPT: Escalation broader: Incident ← not reflected in Incident's narrower CONCEPT: Resolution broader: Incident ← not reflected in Incident's narrower SEVERITY: MEDIUM (INVERTED REFERENCE — inconsistency, not breakage) Corrected entry: see Section 3. ``` --- ``` CHECK 9 — TOP CONCEPT CONSISTENCY STATUS: FAIL SEVERITY: MEDIUM (Type B) Type A check: Concepts declared as top concepts (broader: top concept) — Incident, Problem, Change Request, Category — none also declare a narrower broader target. ✓ Type B check: Concepts with no broader and no topConceptOf: Service Request — already flagged in Check 3 (orphan). Per rules, flagged once only (Check 3 fires first). Not re-flagged here. No additional Type B cases beyond Service Request. ✓ STATUS: PASS (no new violations beyond Check 3) Evidence: All four declared top concepts (Incident, Problem, Change Request, Category) are consistent — none carry a broader relationship to another concept. The one concept lacking both broader and topConceptOf (Service Request) was already captured in Check 3. ``` *(Status set to PASS here — Check 9 Type B overlap with Check 3 is suppressed per rules.)* --- ``` VIOLATION SUMMARY: CRITICAL violations: 2 (Check 1, Check 2) HIGH violations: 2 (Check 3, Check 8 sub-case A resolved; Check 8 INVERTED is MEDIUM) MEDIUM violations: 1 (Check 8 — Inverted Reference) TOTAL violations: 5 Checks passed: 5 / 9 ``` --- **Refused inferences:** ``` REFUSED: That "Priority" is an orphan because it sits beneath Category rather than a top-level incident concept. REASON: Priority has a valid broader: Category, and Category is a declared top concept. The hierarchy is unusual but structurally sound. No evidence warrants flagging it as misplaced. REFUSED: That Resolution's self-reference in related: constitutes a cycle for Check 2 purposes. REASON: Check 2 is defined as broader/narrower chain cycles only. A self-reference in skos:related is a Check 1 violation (self-reference). The two checks are distinct; double-counting would inflate the CRITICAL count without basis. REFUSED: That Escalation and Major Incident form a broader+related redundancy (Check 7). REASON: Check 7 requires the same concept to appear in both broader: and related: of the same concept. Escalation's broader is Incident; its related includes Major Incident — a sibling, not the broader target. Condition not met. ``` --- ## SECTION 3 — CORRECTED CONCEPT INDEX --- ``` ───────────────────────────────────────────────── CONCEPT: SLA Breach [CORRECTED] ───────────────────────────────────────────────── prefLabel: SLA Breach altLabel: SLA Violation definition: An event in which a service level agreement target has not been met. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Major Incident, Escalation, Priority notation: SLA-B Changes applied: • Check 1: Removed self-referential broader: SLA Breach. Assigned broader: Incident as the most semantically appropriate parent (SLA breaches arise in the context of incidents). • Check 2: Self-referential broader was also the source of the degenerate cycle — resolved by the same correction. ───────────────────────────────────────────────── ───────────────────────────────────────────────── CONCEPT: Resolution [CORRECTED] ───────────────────────────────────────────────── prefLabel: Resolution altLabel: Incident Resolution definition: The action or set of actions that restores normal service operation. | Evidence: IT service desk email corpus broader: Incident narrower: none related: Known Error notation: RES Changes applied: • Check 1: Removed self-referential related: Resolution from the related list. ───────────────────────────────────────────────── ───────────────────────────────────────────────── CONCEPT: Service Request [CORRECTED] ───────────────────────────────────────────────── prefLabel: Service Request altLabel: none definition: A formal user request for something new — access, information, or a standard change. | Evidence: IT service desk email corpus broader: top concept narrower: none related: Change Request notation: SRQ topConceptOf: IT Incident Management Taxonomy Changes applied: • Check 3: Added topConceptOf declaration and set broader: top concept. Service Request is a peer of Incident, Problem, and Change Request in ITIL terms; top concept placement is semantically appropriate. ───────────────────────────────────────────────── ───────────────────────────────────────────────── CONCEPT: Incident [CORRECTED] ───────────────────────────────────────────────── prefLabel: Incident altLabel: IT Incident definition: An unplanned interruption to an IT service or reduction in quality. | Evidence: ITIL v4 Service Management broader: top concept narrower: Major Incident, Recurring Incident, Escalation, Resolution, SLA Breach related: Problem, Change Request notation: INC Changes applied: • Check 8: Added Escalation, Resolution, and SLA Breach to narrower list to mirror their broader: Incident declarations and resolve the inverted reference inconsistency. ───────────────────────────────────────────────── ``` --- ## SECTION 4 — VALIDATION VERDICT ``` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VALIDATION VERDICT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SCHEME: IT Incident Management Taxonomy CONCEPTS: 12 CHECKS RUN: 9 / 9 VIOLATIONS: 5 total — CRITICAL: 2 | HIGH: 2 | MEDIUM: 1 VERDICT: HALT Triggered by: 2 CRITICAL violations (Checks 1 and 2) and 2 HIGH violations (Checks 3 and 8). Do not use this scheme downstream. Apply corrections in Section 3 and re-run validation. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CHECK SUMMARY: Check 1 Self-Reference: FAIL — CRITICAL Check 2 Cycles: FAIL — CRITICAL Check 3 Orphans: FAIL — HIGH Check 4 Duplicate prefLabel: PASS Check 5 Missing prefLabel: PASS Check 6 prefLabel=altLabel: PASS Check 7 Broader+Related: PASS Check 8 Dangling References: FAIL — MEDIUM (Inverted) Check 9 TopConcept Consist.: PASS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ``` **Verdict rationale:** Two CRITICAL violations — SLA Breach's self-referential `broader` (creating an infinite traversal loop) and Resolution's self-referential `related` — are sufficient alone to trigger HALT, with the broader/narrower mirroring gaps and the orphaned Service Request compounding the structural risk. Apply the four corrected entries in Section 3 (SLA Breach, Resolution, Service Request, Incident), then re-run validation; the corrected scheme should pass cleanly given that Checks 4–7 and 9 are all green. --- ## SECTION 5 — DOWNSTREAM HANDOFF **Verdict is HALT.** Apply all CRITICAL and HIGH corrections from Section 3 before any downstream use: 1. **SLA Breach** — replace `broader: SLA Breach` with `broader: Incident` 2. **Resolution** — remove `Resolution` from its own `related` list 3. **Service Request** — add `topConceptOf` declaration and `broader: top concept` 4. **Incident** — extend `narrower` list to include Escalation, Resolution, and SLA Breach Do not pass this scheme to **Prompt Ontology Designer™** or **RAG Evaluation Ontology™** in its current state. The self-referential cycle on SLA Breach will cause hierarchy traversal to loop indefinitely; the orphaned Service Request will be unreachable through any hierarchy walk; the inverted narrower references on Incident will produce inconsistent parent-child resolution in any SKOS-aware system. Re-run **CONCEPT SCHEME VALIDATOR™ v1.1** after applying Section 3 corrections. No re-validation is required for the MEDIUM-only Check 8 fix in isolation, but a full re-run is warranted here given the CRITICAL violations.
