Material Core (MatCore) is a metadata standard for computational materials science. MatCore represents key aspects of a material-focused computation to make it understandable to the broad materials research community. It provides pragmatic and workable guidelines for documentation of materials data.

MatCore is developed as a grassroots effort by experts in first principles calculations (DFT, GW), molecular dynamics, phase field, machine learning for materials, and related fields.

MatCore is funded by the National Science Foundation, Division of Materials Research (DMR) through Award #2404283.
