pmd3.x Version der 42CrMoS4 Zugversuchsdaten (https://github.com/materialdigital/demodata_tensiletest_42CrMoS4/) Demonstration of modelling of material charaterization experiments with PMDco. Results of tensile tests on round bar specimens are reported. The material tested is the quenched and tempered steel 42CrMoS4. The aim of the test series is to determine the influence of different heat treatments on the tensile strength and behavior under tensile loading. Exemplary micrographs and microstructure information are provided. The compilation of all related information is still ongoing. The processes of specimen machining, heat treatment, tensile testing, and microstructure analysis have initially been described in PMDCO-2.07 based on the PMD Tensile Test Ontology (TTO). Within this dataset, a mapping in PMDCO-3.x is executed. However, the results are not officially approved. Examples of SPARQL queries are provided.

Demo of creation and query sematic documents created on the basis of catena-x samm model payloads. Uses a YARRRML mapping, found here https://dataportal.material-digital.de/dataset/samm-batch-map that created the necessary tripples. To test this urself copy the link to the mapping into the mapping url field of the application found here https://rdfconverter.matolab.org/.

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

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.

This dataset documents the conversion of a steel product inspection document from the **Manufacturing-X dataspace** into a **[PMDCo](https://github.com/materialdigital/core-ontology)**-conformant knowledge graph. The source data is an [Asset Administration Shell (AAS) inspection document](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/inspectiondocument_316_4401_alloy.json) for cold-rolled stainless steel 316/4401, conforming to the EN 10204 standard as used in the Manufacturing-X dataspace. ## Conversion Pipeline 1. The [AAS inspection document](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/inspectiondocument_316_4401_alloy.json) is loaded into a triplestore using the [AAS2KG tool](https://github.com/MI-FraunhoferIWM/AAS2KG-inspection-documents-of-steel-products) 2. A [SPARQL CONSTRUCT query](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/inspectiondocument_aas2kg_mapping.sparql) transforms the AAS RDF into PMDCo-conformant triples, extracting mechanical properties (tensile strength, yield strength, elongation) and chemical composition (9 elements) as PMDCo quality entities with QUDT-typed measurement datums 3. The [output graph](https://dataportal.material-digital.de/dataset/source record/resource/source record/download/inspectiondocument_316_4401_alloy_pmdcore.ttl) is a standalone PMDCo knowledge graph of the stainless steel material ## Part of Cross-Dataspace Demonstration This dataset is part of a three-dataset series: - [cross-project-use-case](https://dataportal.material-digital.de/dataset/cross-project-use-case) — Catena-X SAMM → PMDCo conversion - **This dataset** — 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 The pipeline is demonstrated here https://github.com/MI-FraunhoferIWM/AAS2KG-inspection-documents-of-steel-products and the RDF data generated is exported into DSMS platform https://pmdx.materials-data.space/knowledge/dataset/inspectiondocument316-4401bb791e14-2532-46c7-a7ea-82d332bd35d3-bfbb73ef
