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.

iof-sieving is a MatPortal dataset catalogue entry listed under PMD, catalogued under source association source record. It includes 11 linked resources with formats such as CSV, SPARQL, text/turtle, json-ld, text/turtle; charset=utf-8, including sieveDistribution-AMMD.csv, SPARQL, merged.ttl. The original short source note was: Demo dataset for iof sieving data. It is published in MatPortal by admin for dataset discovery, linked-data browsing, and assistant/RAG indexing.

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
