Vocabulary v1 · stable IRIs · machine-readable contract

JouleClaw vocabulary, v1.
A globally unambiguous IRI for every field.

The JouleClaw wire forms — cascade receipt, policy receipt, workspace manifest, agent identity, policy actions and decisions — are stable across three byte-equal reference implementations. This vocabulary maps every field to a stable IRI so a JSON-LD parser, a SPARQL store, or a generic third-generation agent client can read JouleClaw output as RDF without bespoke integration. It is purely additive: existing consumers keep working unchanged.

Quickstart

Add one field to any JouleClaw receipt. JSON-LD readers expand it into typed RDF triples; existing JSON readers ignore it.

Classes

Each class has a stable IRI under https://jouleclaw.transaction.science/vocab/v1#. Classes that align with W3C PROV-O subclass it (ClaimProvenance → prov:Entity, AuditEvent → prov:Activity, AgentIdentity → prov:Agent) so PROV-O consumers reason about JouleClaw output without any JouleClaw-specific knowledge beyond this vocabulary.

jc:Receipt #

One signed thermodynamic record per cascade walk; schema id "1". See SPEC.md §2.

jc:PolicyReceipt #

One signed audit record per policy evaluation; schema id "policy/1". See SPEC.md §10.

jc:WorkspaceManifest #

Content-addressed manifest of a persistent agent workspace; schema id "workspace/1". See SPEC.md §11.

jc:WorkspaceEntry #

One named entry inside a WorkspaceManifest — path, content_hash, size, kind.

jc:AgentIdentity #

did:key-bound Ed25519 identity. Subclass of prov:Agent. See SPEC.md §8.

jc:ToolTouch #

One tool invocation observed during a cascade walk.

jc:ToolReceipt #

HMAC-signed gateway attestation that a tool was invoked, observed by the gateway, not the model.

jc:ClaimProvenance #

Provenance of one retrieved claim that fed the cascade resolution. Subclass of prov:Entity.

jc:Citation #

Span-level grounding linking an output byte range to a retrieval chunk.

jc:TextSpan #

Half-open byte range [start, end) over an output text.

jc:TokenAttribution #

Per-token attribution row produced by a TokenAttributor.

jc:IntentVerdict #

Query-intent classification verdict (six-variant taxonomy).

jc:Action #

What a JouleClaw agent is about to do — filesystem, network, or process. See SPEC.md §9.

jc:FsAction #

Filesystem action subclass of Action.

jc:NetAction #

Network action subclass of Action.

jc:ProcAction #

Process action subclass of Action.

jc:Decision #

Output of one policy evaluation — Allow or Deny.

jc:Allow #

Decision subclass — permitted by a named rule.

jc:Deny #

Decision subclass — refused; carries a DenyReason.

jc:AuditEvent #

Append-only record of one policy evaluation. Subclass of prov:Activity.

Enumerations

jc:Cascade #

Five energy-class cascade tiers.

  • jc:Cache (L0)
  • jc:Lawful (L1)
  • jc:Embed (L2)
  • jc:Model (L3)

jc:Provenance #

Honesty tier of an energy counter; the breaker enforces at the worst counter seen.

  • jc:ModelBased
  • jc:Estimator
jc:FsMode #

Filesystem access modes.

  • jc:FsRead
  • jc:FsWrite
  • jc:FsExecute

jc:DenyReason #

Why a Deny decision was returned.

  • jc:NoMatchingAllow
  • jc:ExplicitDeny
jc:EntryKind #

Workspace entry type tag.

  • jc:Blob
  • jc:Text
  • jc:Structured
jc:SensitivityLevel #

Four-level data sensitivity taxonomy used by the privacy-classifier route filter; numerically ordered.

  • jc:Public
  • jc:Internal
  • jc:Confidential
  • jc:Restricted

Properties

Every property in the JouleClaw data model. The JSON field is what appears in receipts on the wire today; the IRI is what a JSON-LD parser produces when the v1 context is in scope; the range is the typed shape the value MUST take.

Versioning

A future major bump of the vocabulary publishes under /vocab/v2#. v1 IRIs remain resolvable forever — per the JouleClaw open-standard "names are final" rule.
