📘 1. SYNCTX Ontology (TTL)

This ontology defines the HDIP-owned Synthetic Context vocabulary used to represent a platform-generated, versioned relational and constraint projection for synthetic-data generation.

SYNCTX is deliberately referential. It does not redefine generic Product, Product Version, Data Product, schema, policy, provenance, or enterprise semantic concepts owned by BPS/PIN, GEDRM/GEDRA, W3C PROV, or other authoritative specifications.

Core principle: SYNCTX compiles and correlates authoritative Product Version, semantic, schema, contract, constraint and governance references for a defined synthetic-generation purpose. It does not become the source authority for those referenced semantics.

🧠 Key Design Notes (TTL)

✔ SYNCTX is a first-class HDIP-owned construct​

synctx:SyntheticContext a owl:Class

SYNCTX owns the context projection and binding semantics required by HDIP synthetic-data generation. It does not own the generic Product, Product Version, Data Product, policy, provenance or enterprise semantic concepts it references.

✔ Members are Product Versions​

SYNCTX
   +--> Payment Data Product Version v3
   +--> Party Data Product Version v5

The operative membership is Product-Version-specific because schema, semantics, contracts and constraints may change between versions.

Parent Product identity remains available through BPS isVersionOf / hasVersion relationships.

Historical rule: a later Product Version does not silently rewrite an already-compiled SYNCTX version.

✔ Relationship bindings are explicit and typed​

Instead of an arbitrary literal such as:

relationshipType = "foreign_key"

SYNCTX represents a validated binding that may separately reference:

semantic relationship
technical join/key binding
controlled relationship kind

Therefore:

same field name != relationship
same datatype != foreign key
semantic relationship != executable join automatically

✔ Constraints are projections of authoritative obligations​

SYNCTX does not create a second policy vocabulary.

A ConstraintProjection points to the authoritative policy, contract, rule or control obligation and carries only the information required to compile/apply it within the synthetic-generation context.

✔ SYNCTX does not produce Products​

SYNCTX is declarative context. It does not itself perform generation.

SYNCTX
   |
   v
Synthetic-generation activity / execution
   |
   v
Generated Data / Data Asset
   |
   | intentional Product constitution, if applicable
   v
Synthetic Data Product

Therefore:

generated output != Product automatically
Synthetic classification != mandatory SYNCTX realization

If a Product realization uses SYNCTX, the applicable HPD/operational projection should reference the SYNCTX version used.

✔ Request context and platform application are distinct​

requestedBy
requestedFor
appliedBy

replace the earlier overloaded contextOwner / enforcedBy formulation.

The HDIP capability applying SYNCTX does not thereby become the owner of the underlying policy, Product or Data semantics.

✔ SYNCTX versions preserve historical meaning​

Once a SYNCTX version has been used for generation, material changes to its member Product Versions, relationship bindings, constraints, purpose or generation requirements should result in a new SYNCTX version, not silent mutation of the historical context.

identity != version
version != currentness
revision != deletion

✔ Authority boundaries​

BPS / PIN
  -> Product and Product Version semantics

GEDRM / GEDRA
  -> Data and Data Product semantics / architecture

W3C PROV
  -> generic provenance / revision semantics

HDIP SYNCTX
  -> Synthetic Context projection and binding semantics

And explicitly:

HDIP SyntheticContext != GEAIRM AI Context

A generated asset governed by SYNCTX may later participate as a resource in an AI Context, but the two context concepts are not equivalent.

📄 3. Example SYNCTX Instance (JSON-LD)

This example binds specific Product Versions and references governed relationship/constraint resources. The identifiers are illustrative.

{
  "@context": "https://kivanura.org/context/synctx.jsonld",

    "https://kivanura.org/data/product/PartyDataProduct/version/5"
  ],

  "relationships": [
    {
      "id": "https://kivanura.org/data/synctx/SYNCTX-AI-TRAINING-001/v1/relationship/payment-party",
      "type": "RelationshipBinding",
      "fromVersion": "https://kivanura.org/data/product/PaymentDataProduct/version/3",
      "toVersion": "https://kivanura.org/data/product/PartyDataProduct/version/5",

      "joinBindingRef": "https://kivanura.org/data/contracts/payment-party-key-binding/v2"
    }
  ],

  "constraints": [
    {
      "id": "https://kivanura.org/data/synctx/SYNCTX-AI-TRAINING-001/v1/constraint/privacy-1",
      "type": "ConstraintProjection",
      "constraintKindRef": "https://kivanura.org/hdip/vocab/constraint-kind/privacy",
      "constraintRef": "https://kivanura.org/policy/no-direct-identifiers/v4",
      "constraintValue": "no_direct_identifiers"
    }
  ],

  "requestedBy": "https://example.org/org/AIEngineering",
  "requestedFor": "https://example.org/initiative/FraudModelTraining",
  "appliedBy": "https://kivanura.org/platform/DPFI",

  "associatedGeneratedAssets": [
    "https://kivanura.org/data/asset/synthetic-payment-batch/2026-10-09",

  "versionIdentifier": "1.0.0",
  "statusRef": "https://kivanura.org/hdip/vocab/context-status/current"
}

The generated assets above are not inferred to be Products merely because they were generated under SYNCTX. If they are intentionally constituted as Products, BPS/PIN and the applicable Data Product semantics determine that Product status separately.

🔥 Final Mental Model

🔹 SYNCTX in HDIP​

Authoritative Product Versions
+ schemas / semantic relationships
+ contracts / controls / policy references
+ governed synthetic-generation purpose
                 |
                 v
              PDEP
         DPFI compilation
                 |
                 v
             SYNCTX vN
   relational + constraint projection
                 |
                 v
     Synthetic-generation activity
                 |
                 v
          Generated Data
                 |
          [if productized]
                 v
      Synthetic Data Product

🔹 Interaction with HPD​

HPD for Product Version
        |
        +--> references applicable SYNCTX version

SYNCTX
        |
        +--> references Product Versions
        +--> references validated relationship bindings
        +--> references authoritative constraints
        +--> may reference generation activity / generated assets

SYNCTX does not replace HPD, DPROD, DPDS, Product Version semantics, Data Contracts, policy authority or provenance. It is the HDIP projection that binds the subset of those authoritative references required for governed synthetic-data generation.
