ESKA v0.2.0

ESKA v0.2.0

eska-v0.2.0 is the second governed repository release of the Executable Semantic Knowledge Architecture.

Main semantic change

The ESKA core module advances from 0.1.0 to 0.2.0 with the reviewed cross-repository Semantic Modeling alignment:

eska:SemanticModel owl:equivalentClass smo:SemanticModel .

The reusable semantic-model concept is canonically owned by the published Semantic Modeling Ontology (SMO), while the already-published ESKA class remains a compatibility surface.

ESKA core records its dependency on immutable SMO v0.1.0 using:

<https://w3id.org/eska/model/core>
    dcterms:requires <https://w3id.org/smo/0.1.0> .

This release deliberately does not deprecate eska:SemanticModel, change eska:usesSemanticModel, introduce owl:imports, or move ESKA-specific Capability, Execution, Result, Verification, Service, Agent, or Deployment semantics into SMO.

Published ontology modules

Module	Version	Ontology IRI
core	0.2.0	https://w3id.org/eska/model/core
capability	0.2.0	https://w3id.org/eska/model/capability
service	0.4.0	https://w3id.org/eska/model/service
agent	0.3.0	https://w3id.org/eska/model/agent
deployment	0.1.0	https://w3id.org/eska/model/deployment

Repository release versioning remains independent from the semantic versions of the contained ontology modules.

Compatibility and executable evidence

The release preserves the stable ESKA term namespace:

https://w3id.org/eska#

The core still exposes exactly the same ESKA term inventory; the new ontology axiom is backward-compatible and adds machine-readable equivalence to https://w3id.org/smo#SemanticModel.

The governed verification contract continues to cover seven executable-semantic modes, sixteen semantic Executions, generalized Knowledge Service and Knowledge Agent behavior, deployment binding, and provenance/evidence lineage. Publication verification additionally checks the SMO bridge, the immutable SMO dependency, non-deprecation of the ESKA compatibility class, and consistency between the five authoritative modules and the combined RDF distribution.

Release bundle

The GitHub Release attaches:

• dist/eska.ttl;
• the five authoritative model/eska-*.ttl ontology modules;
• model/publication-contract.json;
• model/namespace-migration.json;
• publication/backend-targets.json.

The immutable Git tag provides the governed backend needed for the future core 0.2.0 W3ID version routes.

Publication boundary

At release creation time the current ESKA routes remain live, the existing immutable routes remain bound to eska-v0.1.0, and these new routes remain intentionally inactive:

https://w3id.org/eska/model/core/0.2.0
https://w3id.org/eska/dist/0.2.0/eska-core.ttl

After this release exists, the tagged core backend must be verified independently. Only then may a separate W3ID contribution activate those two routes against eska-v0.2.0. Immutable routes must never target mutable main.

ESKA v0.1.0

ESKA v0.1.0

eska-v0.1.0 is the first governed repository release of the Executable Semantic Knowledge Architecture.

Permanent semantic identity

This release is the first repository snapshot governed under the permanent W3ID namespace:

https://w3id.org/eska#

The provisional urn:eska:core: identifiers remain recorded only as historical predecessors in model/namespace-migration.json.

Published ontology modules

Module	Version	Ontology IRI
core	0.1.0	https://w3id.org/eska/model/core
capability	0.2.0	https://w3id.org/eska/model/capability
service	0.4.0	https://w3id.org/eska/model/service
agent	0.3.0	https://w3id.org/eska/model/agent
deployment	0.1.0	https://w3id.org/eska/model/deployment

Repository release versioning is independent from the semantic versions of the contained ontology modules.

Executable evidence

The governed release preserves the verified reference architecture covering seven executable-semantic modes, sixteen semantic Executions, generalized Knowledge Service and Knowledge Agent behavior, blue/green Deployment binding, five operational invocation lineages, and provenance/evidence lineage to immutable Pizza semantic sources.

The publication contract verifies five ontology modules and 53 declared ESKA terms. The external W3ID verifier checks 14 live HTML/Turtle routes and requires the permanent post-migration identifiers.

Release bundle

The GitHub Release attaches the combined RDF distribution and the five authoritative ontology module files. The immutable Git tag also provides a stable repository snapshot for documentation, provenance, and future versioned W3ID routes.

Publication boundary

Unversioned W3ID identifiers remain the stable current semantic/publication routes. Versioned W3ID module/distribution routes may be activated only against immutable targets derived from this governed release; they must never be redirected to mutable main content.
