DPROD
DPROD is the OMG Data Product Ontology. The EKGF DPROD page describes it as an OMG standard for describing data products using W3C Linked Data technologies. DPROD profiles DCAT and adds data-product concepts such as input ports, output ports, quality, governance, and accountability.
Buyer question
“Can WWKG publish workspaces as governed data products instead of just storing graph data?”
WWKG fit
| Assessment area | WWKG fit | Status |
|---|---|---|
| Data product identity | A WWKG workspace can be treated as the operational unit behind a data product: encrypted, versioned, queryable, and owned. | Native fit |
| Decentralized publishing | WWKG’s peer-to-peer architecture and workspace model match DPROD’s decentralized data-product intent. | Native fit |
| Catalog metadata | WWKG already has DCAT-oriented catalog groundwork and workspace catalog concepts. | Partial fit |
| Product ports | WWKG query endpoints, graph services, exports, and future app surfaces are natural output ports. Loaders, ETL workflows, and branch-based imports are natural input ports. | Partial fit |
| Contracts between parties | DPROD 1.1 is expected to add data contracts. WWKG’s DIDs, branch history, validation rules, provenance, and encrypted membership model are the right substrate, but first-class DPROD data contracts are not complete yet. | Roadmap |
What WWKG can say
WWKG is designed to make a workspace publishable as a data product: data, schema, rules, provenance, ownership, access, and versions can all live in the same graph-controlled asset.
That gives a buyer a clean operating model:
- The workspace is the controlled data-product boundary.
- Branches and commits describe product versions and change history.
- SHACL and validation rules describe product quality requirements.
- PROV-style provenance records who created, changed, reviewed, and merged product content.
- Encryption and workspace membership describe who can read the product.
- DCAT/DPROD metadata can describe the product for discovery and marketplace use.
Assessment boundary
Today, WWKG provides the architecture and DCAT groundwork for native DPROD support. Full DPROD publishing becomes a stronger assessment point as DPROD metadata, ports, product lifecycle, and contract metadata become first-class product surfaces.
DPROD data products and data contracts are therefore best treated as a strategic WWKG direction backed by existing workspace, catalog, validation, provenance, and access-control primitives.
