PMD-X Cross Dataspace Demo

PMD

This dataset demonstrates how material information from two independent industrial dataspaces — Catena-X and Manufacturing-X — can be jointly represented and queried as a unified PMDCo knowledge graph.

Scenario

The object of interest is a tension pulley assembly composed of two parts from different manufacturers and dataspaces.

Part 1 — Pulley Wheel (Catena-X) Material: PA 66 GF 30 — see cross-project-use-case

Part 2 — Tensioner Bracket (Manufacturing-X) Material: Steel AISI 304 — see steel-inspection-document-mapro

The assembly graph represents the tension pulley using PMDCo and BFO part-whole relations. Component IRIs link into the material graphs from both source datasets. All three graphs are loaded into this dataset's Fuseki triplestore, enabling joint SPARQL queries that traverse from the physical object through its parts into material properties originating from two separate dataspaces.

An example SPARQL query demonstrates this joint querying capability. Or a simple on directly here Query
