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 December 13, 2023. For additional information, contact Mat Portal Admin (matadmin@nodomain.org).

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).
