Dataset

Cross Project Use Case

This dataset documents the conversion of polymer material data from the **Catena-X dataspace** into a **[PMDCo](https://github.com/materialdigital/core-ontology)**-conformant knowledge graph. The source data is a PA6GF30 (30% glass-filled polyamide 6) material property dataset conforming to the [SAMM `MaterialData` aspect model](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/materialdataam3010.ttl) as used in the Catena-X dataspace standard. ## Conversion Pipeline 1. [Instance data](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/material_data_test_pa6gf30.json) is retrieved from a Catena-X dataspace via an Eclipse Dataspace Connector (EDC) 2. The JSON is converted to RDF using the RDFConverter tool with a SAMM-specific YARRRML mapping, producing the [SAMM semantic document](PLACEHOLDER_DATASET1_JOINED_TTL) 3. A [SPARQL INSERT query](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/pmdco-mapping-insert.sparql) transforms the SAMM representation into PMDCo-conformant triples, mapping SAMM units to QUDT equivalents and material properties to PMDCo quality classes 4. The [output graph](PLACEHOLDER_DATASET1_PMDCO_TTL) is a standalone PMDCo knowledge graph of the PA6GF30 material The [SAMM aspect model schema](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/materialdataam3010.ttl) and the [mapping diagram](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/samm-pmdco.png) illustrate the conceptual mapping between the two representations. The [Jupyter notebook](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/cross_project_usecase.ipynb) demonstrates the full pipeline end-to-end. ## Part of Cross-Dataspace Demonstration This dataset is part of a three-dataset series: - **This dataset** — Catena-X SAMM → PMDCo conversion - [steel-inspection-document-mapro](https://dataportal.material-digital.de/dataset/steel-inspection-document-mapro) — Manufacturing-X AAS → PMDCo conversion - [pmd-x-cross-dataspace-demo](https://dataportal.material-digital.de/dataset/pmd-x-cross-dataspace-demo) — joint assembly graph and cross-dataspace SPARQL queries An example query on the SAMM graph can be found here:

material_data_test_pa6gf30-joined.ttl

RDF representation of the PA6GF30 material instance data, converted from [material_data_test_pa6gf30.json](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/5f7d5a69-f8f5-49d1-9780-c3ecdc0e11ec/download/material_data_test_pa6gf30.json) using the RDFConverter tool with a SAMM-specific YARRRML mapping. Conforms to the [MaterialData SAMM aspect model](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/2c5241c7-d6dc-46f7-b606-f85db755e49a/download/materialdataam3010.ttl). This is the intermediate representation in the pipeline — the input to [pmdco-mapping-insert.sparql](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/30780c7d-e08b-4607-b83a-c2dd20e44e89/download/pmdco-mapping-insert.sparql) which produces the final PMDCo output graph.

cross_project_usecase.ipynb

Jupyter notebook demonstrating the full Catena-X → PMDCo conversion pipeline. Retrieves material data from a Catena-X dataspace via an Eclipse Dataspace Connector (EDC), converts it to RDF using the [RDFConverter](https://github.com/materialdigital/RDFConverter) tool with a SAMM-specific YARRRML mapping, cleans provenance triples, and loads the result into a triplestore. Requires EDC access credentials and a running RDFConverter instance — see notebook comments for configuration.

  "description": "This dataset documents the conversion of polymer material data from the **Catena-X dataspace** into a **[PMDCo](https://github.com/materialdigital/core-ontology)**-conformant knowledge graph. The source data is a PA6GF30 (30% glass-filled polyamide 6) material property dataset conforming to the [SAMM `MaterialData` aspect model](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/materialdataam3010.ttl) as used in the Catena-X dataspace standard. ## Conversion Pipeline 1. [Instance data](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/material_data_test_pa6gf30.json) is retrieved from a Catena-X dataspace via an Eclipse Dataspace Connector (EDC) 2. The JSON is converted to RDF using the RDFConverter tool with a SAMM-specific YARRRML mapping, producing the [SAMM semantic document](PLACEHOLDER_DATASET1_JOINED_TTL) 3. A [SPARQL INSERT query](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/pmdco-mapping-insert.sparql) transforms the SAMM representation into PMDCo-conformant triples, mapping SAMM units to QUDT equivalents and material properties to PMDCo quality classes 4. The [output graph](PLACEHOLDER_DATASET1_PMDCO_TTL) is a standalone PMDCo knowledge graph of the PA6GF30 material The [SAMM aspect model schema](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/materialdataam3010.ttl) and the [mapping diagram](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/samm-pmdco.png) illustrate the conceptual mapping between the two representations. The [Jupyter notebook](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/cross_project_usecase.ipynb) demonstrates the full pipeline end-to-end. ## Part of Cross-Dataspace Demonstration This dataset is part of a three-dataset series: - **This dataset** — Catena-X SAMM → PMDCo conversion - [steel-inspection-document-mapro](https://dataportal.material-digital.de/dataset/steel-inspection-document-mapro) — Manufacturing-X AAS → PMDCo conversion - [pmd-x-cross-dataspace-demo](https://dataportal.material-digital.de/dataset/pmd-x-cross-dataspace-demo) — joint assembly graph and cross-dataspace SPARQL queries An example query on the SAMM graph can
