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](https://github.com/materialdigital/core-ontology)** 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](https://dataportal.material-digital.de/dataset/cross-project-use-case) **Part 2 — Tensioner Bracket (Manufacturing-X)** Material: Steel AISI 304 — see [steel-inspection-document-mapro](https://dataportal.material-digital.de/dataset/steel-inspection-document-mapro) The [assembly graph](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/tension_pully.ttl) 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](https://dataportal.material-digital.de/dataset/source record/fuseki/$/sparql), 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](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/cross_dataspace_query.sparql) demonstrates this joint querying capability.
