This repository hosts a Jupyter notebook demonstrator that is based on an ontological framework. This framework is structured around the Platform MaterialDigital Core Ontology (PMDco), Tensile Test Ontology (TTO), and Precipitate Geometry Ontology (PGO). This approach allows for a nuanced exploration and demonstration of an examplary Orowan correlation in materials science. This example is provided by the PMD core team.

For more information on these ontologies and the underlying framework, please visit:

• PMDco: Platform MaterialDigital Core Ontology.
• The publication detailing PMDco can be found here: PMD Core Ontology: Achieving semantic interoperability in materials science
• TTO: Tensile Test Ontology
• PGO: Precipitate Geometry Ontology
