📘 1. SYNCTX Ontology (TTL)

This is the canonical semantic model.

@prefix synctx: <https://kivanura.org/spec/hdip/synctx#> .
@prefix dp: <https://kivanura.org/spec/dp#> .
@prefix hpd: <https://kivanura.org/spec/hdip/hpd#> .
@prefix org: <https://kivanura.org/spec/org#> .
@prefix dprod: <https://example.org/ikgf/dprod#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .

🧠 Key Design Notes (TTL)

✔ SYNCTX is a first-class class​

synctx:SyntheticContext a owl:Class

✔ Relationships are modeled explicitly​

Instead of implicit joins:

synctx:Relationship

✔ Members are Data Products​

synctx:hasMemberProduct → dp:DataProduct

✔ Outputs are explicitly linked​

synctx:produces → dp:DataProduct

✔ Ownership is separated​

synctx:contextOwner
synctx:enforcedBy

📦 2. JSON-LD Context for SYNCTX

Now we define the runtime-friendly layer.

🔥 Final Mental Model

🔹 SYNCTX in HDIP Graph​

Data Products
      ↓
SYNCTX (relational boundary)
      ↓
Synthetic Data Products

🔹 Interaction with HPD​

HPD → references SYNCTX
SYNCTX → produces products
