Open Knowledgebase of Interatomic Models
The Open Knowledgebase of Interatomic Models (OpenKIM). is a cyberinfrastructure funded by the United States National Science Foundation (NSF) focused on improving the reliability and reproducibility of molecular and multi-scale simulations in computational materials science. It includes a repository of interatomic potentials that are exhaustively tested with user-developed integrity tests, tools to help select among existing potentials and develop new ones, extensive metadata on potentials and their developers, and standard integration methods for using interatomic potentials in major simulation codes. OpenKIM is a member of DataCite and provides unique DOIs (Digital object identifier) for all archived content on the site (fitted models, validation tests, etc.) in order to properly document and provide recognition to content contributors. OpenKIM is also an eXtreme Science and Engineering Discovery Environment (XSEDE) Science Gateway, and all content on openkim.org is available under open source licenses in support of the open science initiative. Motivation Reliability, reproducibility, and accessibility are foundational to the success of science; in computational materials science these can be achieved through documentation of simulation setup, model parameters, and software version/settings information. The NSF actively supports the development of software and cyberinfrastructure that enable the documentation and distribution of this type of critical data
