    dct: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.\r
\r
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/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/2c5241c7-d6dc-46f7-b606-f85db755e49a/download/materialdataam3010.ttl) as used in the Catena-X dataspace standard.\r
\r
## Conversion Pipeline\r
\r
1. [Instance data](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/5f7d5a69-f8f5-49d1-9780-c3ecdc0e11ec/download/material_data_test_pa6gf30.json) is retrieved from a Catena-X dataspace via an Eclipse Dataspace Connector (EDC)\r
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)\r
3. A [SPARQL INSERT query](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/30780c7d-e08b-4607-b83a-c2dd20e44e89/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\r
4. The [output graph](PLACEHOLDER_DATASET1_PMDCO_TTL) is a standalone PMDCo knowledge graph of the PA6GF30 material\r
\r
The [SAMM aspect model schema](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/2c5241c7-d6dc-46f7-b606-f85db755e49a/download/materialdataam3010.ttl) and the [mapping diagram](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/32121b96-7360-468b-a65b-d775f4685345/download/samm-pmdco.png) illustrate the conceptual mapping between the two representations. The [Jupyter notebook](https://dataportal.material-digital.de/dataset/f2bca6a2-04df-47cb-9439-589e46ba60e2/resource/34889e74-c5da-4545-aabc-e8a12f96cfd3/download/cross_project_usecase.ipynb) demonstrates the full pipeline end-to-end.\r
\r
## Part of Cross-Dataspace Demonstration\r
\r
This dataset is part of a three-dataset series:\r
- **This dataset** — Catena-X SAMM → PMDCo conversion\r
- [steel-inspection-document-mapro](https://dataportal.material-digital.de/dataset/steel-inspection-document-mapro) — Manufacturing-X AAS → PMDCo conversion\r
- [pmd-x-cross-dataspace-demo](https://dataportal.material-digital.de/dataset/pmd-x-cross-dataspace-demo) — joint assembly graph and cross-dataspace SPARQL queries\r
\r

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