materialscommon

Materialscommon is a hypothetical open data framework and repository intended to standardize the collection, annotation, and sharing of materials information across disciplines such as metals, polymers, ceramics, and nanomaterials. The project seeks to enable interoperability by defining a common data model for material identity, properties, processing history, experimental methods, and simulation results. Data entries are described with machine-readable metadata and units, and may be serialized in formats such as JSON-LD, RDF, or XML to support programmatic access and integration with other databases. Governance is community-driven, with open participation, version control for data schemas, and permissive licensing to encourage reuse and redistribution. The initiative covers descriptive metadata as well as quantitative properties, uncertainties, provenance, and data quality flags to aid reproducibility. Applications include reproducibility studies, materials informatics, and accelerated discovery by enabling cross-dataset queries and machine learning models. The project prioritizes provenance, citing source data, measurement conditions, and uncertainty, to support confidence and comparability. Related efforts include the Materials Project and the Materials Genome Initiative, as well as general open-data standards such as the FAIR data principles.
