General information

Precipitate Geometry Ontology (PGO) is a PMD application ontology for representing precipitate-geometry information derived from transmission electron microscopy and related microstructural analysis workflows. It extends PMDco-aligned modeling so precipitate descriptors and linked process/property context can be integrated and queried together in materials knowledge graphs. See more...
Initial created on April 16, 2026. For additional information, contact Mat Portal Admin.

Notes

The Precipitate Geometry Ontology (PGO) is a small ontology used to describe data originating from transmission electron microscopy (TEM) analyses of precipitates. It was created in the frame of the collaborative project Platform MaterialDigital (PMD, https://materialdigital.de). It is further part of a demonstrator showing possible interactions of semantic data created by the application of multiple ontologies and used by federated SPARQL querying - the "Orowan Demonstrator" (available at: https://github.com/materialdigital/demo-orowan).
