Handover — public baseline extended with agentic-network reference case; Pizza stewardship gate remains

[GerhardBalz-Admin]

Purpose

Provide the durable public handover for the Semantic Knowledge Engineering initiative after the cross-example evidence cycle, standards-first MOD adoption, public reference-example publication, W3ID activation for SMO/ESKA, the 14 August 2026 public current-state/discovery cleanup, the 16 August 2026 addition of the Semantic Agentic Network Operations industrial architecture reference case, and the 24 August 2026 adoption and downstream reconciliation of the initiative-level semantic-continuity principle.

Repository-local semantics and implementation remain owned by their respective repositories.

Verified initiative state

Public initiative/reference repositories

The following repositories are public:

• GerhardBalz/semantic-knowledge-engineering
• GerhardBalz/semantic-modeling-ontology
• GerhardBalz/executable-semantic-knowledge-architecture
• GerhardBalz/pizza-ontology
• GerhardBalz/semantic-modeling-pizza
• GerhardBalz/semantic-modeling-wine-food
• GerhardBalz/semantic-agentic-network-operations

GerhardBalz/w3id.org remains supporting publication infrastructure rather than a semantic initiative repository.

Completed semantic / publication baseline

Completed outcomes include:

• Pizza ↔ Wine/Food cross-domain evidence review;
• governed SMO v0.1 with deliberately narrow smo:SemanticModel and smo:ImplementationProjection vocabulary;
• standards-first reuse of MOD mod:competencyQuestion rather than new SMO vocabulary;
• ESKA core 0.2.0 alignment with SMO v0.1;
• active permanent and immutable W3ID publication for SMO and ESKA;
• public Semantic Modeling Pizza and Wine/Food reference examples;
• current-state README/discovery cleanup across the original six public repositories;
• normalized contribution guidance for both semantic-modeling reference examples;
• the optional informal “42” semantic-context illustration;
• public Semantic Agentic Network Operations reference case bootstrapped and reviewed via GerhardBalz/semantic-agentic-network-operations#1;
• SKE PR Adopt explicit semantic-continuity principle and refresh initiative state #40 merged on 24 August 2026, adopting “Semantics must remain explicit through execution.” as the primary initiative-level principle while retaining “Execution must not sever semantics.” as explanatory failure-mode shorthand;
• ESKA PR #95 merged on 24 August 2026, reconciling the current ESKA README, semantic-continuity guide, related-work positioning, and active Pizza reference documentation;
• SKE Refine semantic-continuity principle: “Semantics must remain explicit through execution” #39 closed completed after live verification of the merged downstream ESKA wording.

The reviewed semantic-continuity principle implies preservation, traceability, explicitness/inspectability, and provenance. It does not require an ImplementationProjection in every execution path: a source-owned semantic artifact may participate directly in execution; when a projection is introduced, the relevant meaning and lineage must remain explicit and traceable.

Current architectural conclusions remain:

• do not expand SMO for structural symmetry;
• DCTERMS/PROV remain sufficient for demonstrated source/lineage relationships;
• Pizza-specific exclusions remain local;
• operation signatures, runtime context, agent contracts, and execution architecture remain local or ESKA-owned as appropriate;
• negative cross-domain evidence is evidence against forced vocabulary promotion;
• an industrial architecture case may test SKE/SMO/ESKA without introducing a new domain ontology;
• in the agentic-network reference case, MCP is treated primarily as a realization of the governed agent tool plane, not as the whole Agentic Network Operations Platform;
• the mapping to Soldani et al.'s public Network MCP proposal is an independent interpretation, not a claim that the cited work uses SKE terminology.

Public industrial architecture reference — Semantic Agentic Network Operations

Repository:

GerhardBalz/semantic-agentic-network-operations

Technology-neutral platform concerns:

Agentic Network Operations Platform
├── Agent orchestration and lifecycle
├── Intent translation and transactional execution
├── Agent tool plane
├── Identity, policy and governance
├── Validation, conflict resolution and enforcement
└── Observability and audit

The reference case tests the SKE/SMO/ESKA semantic-continuity hypothesis:

Authoritative semantics
        ↓
Semantic Model
        ↓
Implementation Projection — when used
        ↓
Executable Semantic Knowledge
        ↓
Agent / tool transaction
        ↓
Evidence + provenance

A source-owned semantic artifact may also participate in execution directly. The invariant is continuity of relevant meaning and lineage, not mandatory projection.

It is an independent architecture/reference-evidence repository, not a telecom ontology or standards proposal. No affiliation with or endorsement by cited authors, employers, standards bodies, or organizations is implied.

Any one-to-one expert contact, response status, or meeting follow-up remains private. Publication-safe technical conclusions may be promoted publicly only when they can stand independently and with permission where required.

Active P1 — Pizza Ontology #72 external stewardship/provenance gate

Active issue:

GerhardBalz/pizza-ontology#72 — Establish resolvable Pizza preservation/reference identifiers and eliminate misleading non-resolving links.

The proposed namespace remains:

https://w3id.org/pizza-ontology/

strictly as a preservation/reference PID, not a replacement Pizza ontology namespace.

External stewardship/provenance feedback must be received and assessed before any perma-id/w3id.org pull request is submitted. Detailed one-to-one outreach and follow-up status are intentionally tracked privately rather than in this public technical handover.

Therefore:

• do not submit a Pizza W3ID PR yet;
• do not list an external maintainer without explicit agreement;
• do not change historical Pizza ontology/version/entity IRIs;
• do not treat the proposed namespace as active;
• assess external stewardship/provenance feedback before changing the publication plan.

Parked P2 — Pizza Ontology #4

GerhardBalz/pizza-ontology#4 remains parked.

Do not create a successor Pizza ontology merely for modern tooling, dereferenceability, or publication UX. Activate it only when a concrete semantic-modernization requirement requires changed/new domain semantics or a new actively governed ontology identity.

Current public backlog

SKE
  #32  ACTIVE — durable public handover
  #39  COMPLETE — semantic-continuity wording + ESKA reconciliation

SMO
  no open issues

ESKA
  no open issues — PR #95 merged

Pizza Ontology
  #72  ACTIVE P1 — external stewardship/provenance gate
  #4   PARKED P2 — successor ontology only on concrete semantic trigger

Semantic Modeling Pizza
  no open issues

Semantic Modeling Wine/Food
  no open issues

Semantic Agentic Network Operations
  no open issues — reviewed bootstrap baseline merged

Repository-discovery metadata and relationship/outreach planning may have private execution items, but private relationship state is not part of this public handover.

Immutable / governance boundaries

Do not:

• modify or retag immutable eska-v0.1.0, eska-v0.2.0, or smo-v0.1.0;
• expand SMO for structural symmetry;
• move ESKA execution concepts into SMO without independent semantic-modeling evidence;
• rewrite historical Pizza 2.0 ontology/version/entity identifiers;
• claim authority over the historical Pizza namespace;
• submit Pizza W3ID before stewardship/provenance feedback is received and assessed;
• create new repositories merely because another reference domain exists;
• present the Semantic Agentic Network Operations interpretation as if it were terminology or architecture claimed by Soldani et al.;
• imply endorsement or publish private peer-contact status.

Restart instruction

Use:

Review GerhardBalz/semantic-knowledge-engineering#32 as the current SKE public handover and verify live GitHub state first. The initiative-level principle “Semantics must remain explicit through execution.” is adopted and reconciled through SKE PR #40 and ESKA PR #95; SKE #39 is complete. Start with Pizza Ontology #72 by checking whether the external stewardship/provenance gate has changed; preserve historical Pizza identity and do not submit W3ID before stewardship/provenance feedback. If #72 remains externally blocked, continue with newly opened independent technical backlog items rather than inventing vocabulary or repositories. Keep one-to-one expert/contact status private.

Completion rule

Keep this issue open while it is the active durable public checkpoint.

Before replacing or closing it:

1. create/update the next durable handover checkpoint;
2. ensure the SKE roadmap/repository map reflects actual GitHub state;
3. ensure repository-local issues capture every active implementation/governance gate;
4. ensure no user-reviewed technical decision or external dependency exists only in chat history;
5. keep one-to-one outreach/contact status out of the public handover.

Post-publication cleanup complete: SKE PR #33 merged as 5a40c59c2504301ad97f7d8ef1dc36fd165ae5cb; SKE #29, #27, and #22 are closed. SKE #32 is now the sole durable handover. The audited initiative has no open SMO, ESKA, Semantic Modeling Pizza, or Semantic Modeling Wine/Food issues. Pizza Ontology #72 remains the sole active P1 and is still externally gated on stewardship feedback; Pizza #4 remains parked P2.

Backlog boundary update — 14 Aug 2026

The outreach/discovery planning item initially opened as SKE #34 has been reclassified as private initiative planning because it includes relationship-building, unpublished strategy, contact planning, and public/private decisions.

SKE #34 is closed as a public boundary marker. Detailed planning should continue only in a dedicated private SKE workspace. Public SKE should receive only publication-safe outputs that emerge from that work.

This private planning track remains independent of the Pizza #72 stewardship gate and does not displace the public P1 dependency.

Public backlog refresh — 23 August 2026

Live review found one newer independent public P1 item not yet reflected in this handover body:

• SKE #39 — refine/adopt “Semantics must remain explicit through execution.” as the initiative-level semantic-continuity principle.
• Draft PR #40 implements the initiative-level wording and refreshes README/repository-map/current-sequence for SANO and current backlog state. It remains draft pending review.

Pizza #72 remains independently active and externally gated; no Pizza W3ID action is unblocked by this update.

When this handover is next replaced or rewritten, carry #39 forward unless it has been completed and ensure the seven-repository public baseline remains reflected.

Public checkpoint — OntoJIT related-work publication complete

Live-verified on 25 August 2026:

• ESKA PR #96 — Document OntoJIT as ESKA related work — is merged (a6422ed9e7a161483fc90cc58e43ddbd87bf939e).
• The public note positions OntoJIT as related work rather than as equivalent to ESKA, distinguishes generated C# + semantic meta-properties from the semantic runtime/inference support needed to interpret them, and records the CWA/OWA/runtime-semantics lesson.
• The existing SKE/ESKA invariant remains unchanged: ImplementationProjection is optional; when a projection is used, relevant meaning, assumptions and lineage must remain explicit through runtime interpretation and execution.
• No SMO/ESKA vocabulary, immutable release, runtime, or outreach boundary changed.

This is publication-safe technical state only; any opportunity/contact tracking remains private.

Publication-safe checkpoint — 25 August 2026:

• Public SKE PR Add SKE concept and responsibility map #41 was reviewed and squash-merged as ed41e2a2bcb312ca3af31f12ba99fcfad240cdea.
• SKE now publishes landscape/concept-map.md, linked from the README.
• The map uses kind × architectural concern × evidence status so standards/vocabularies, serializations, protocols, tools/runtimes, publication infrastructure, SKE-owned concepts, related work, and reference/falsification evidence are not flattened into one hierarchy.
• It preserves key boundaries including: RDF/RDFS/IRI as substrate; distinct OWL/SKOS/SHACL roles; distinct PROV-O/DCTERMS/DCAT/MOD roles; W3ID/GitHub as infrastructure rather than semantic authority; replaceable tooling/runtime choices; optional ImplementationProjection; heterogeneous ESKA execution mechanisms; MCP as a partial protocol/tool-mediation realization; and related work separate from initiative evidence.
• No new SKE/SMO/ESKA vocabulary, ontology, repository, or dependency was introduced.

Private contact/opportunity status remains intentionally excluded from this public checkpoint.

Public related-work checkpoint — 25 Aug 2026

Public SKE PR #42 — Document AI Unified Process as SKE related work was explicitly reviewed and squash-merged as 13326f1674799211b43e56f98ae1df1bef434404.

Public SKE now includes a landscape/related-work/ index and a source-grounded AIUP / Spec-Driven Development comparison. The note keeps AIUP's own Specification Core and behavioral authority framing distinct from SKE/SMO/ESKA semantic-authority concerns; semantic mechanisms remain optional and evidence-driven. The proposed Task Manager semantic-integration experiment remains candidate evidence, not completed evidence.

Public checkpoint — 25 August 2026

SKE PR #43 (Document Knowledge Spine as SKE related work) was reviewed and squash-merged as be3e08962f91e8fd853de252e243ab8ee6434d10.

The public related-work index now contains reviewed notes for:

• AI Unified Process / Spec-Driven Development;
• Knowledge Spine.

These notes preserve source terminology first and use SKE only as a comparison lens. They do not imply adoption or endorsement. Private relationship/contact state remains outside this public handover.

Next public review gate — 25 August 2026

SKE PR #44 (Refresh public initiative status after completed SKE cycle) is open and Ready for review at head 18f0224e9fa7c2de0f2095c4217881a169fd67ba.

It synchronizes README.md, roadmap/current-sequence.md, and architecture/repository-map.md with live state after PRs #40–#43: SKE #39 is complete, Pizza #72 is the only active public P1 gate, and the related-work index is linked directly from the README.

Documentation/status synchronization only; no semantic vocabulary, ontology, runtime behavior, repository, or publication identifier changes.

[GerhardBalz-Admin]

Checkpoint — 25 August 2026

The reviewed SKE publication/status cycle is now complete through PR #44, squash-merged as 75a5b4941dbea7fedce5d5c75a95145649f58d09.

Completed public additions in this cycle:

• PR Add SKE concept and responsibility map #41 — concept/responsibility map (landscape/concept-map.md);
• PR Document AI Unified Process as SKE related work #42 — AI Unified Process / Spec-Driven Development related-work note;
• PR Document Knowledge Spine as SKE related work #43 — Knowledge Spine related-work note;
• PR Refresh public initiative status after completed SKE cycle #44 — README, roadmap/current-sequence, and repository-map status synchronization.

The public entry points now correctly mark SKE #39 complete and treat Pizza #72 as the only active public P1 gate. A live search after the PR #44 merge found no open PRs across the eight initiative/private repositories. No new public work should be invented merely because Pizza #72 remains externally blocked; continue only when a new independent evidence-backed item appears or a gated item is deliberately activated.
