The Open Databases Integration for Materials Design (OPTIMADE) consortium aims to make materials databases interoperable by developing a specification for a common REST API.
Designing new materials suitable for specific applications is a long, complex, and costly process. Researchers think of new ideas based on intuition and experience. Their synthesis and evaluation require a tremendous amount of trial and error. In the last few years, there has been a major game change in materials design. Thanks to the exponential growth of computer power and the development of robust first-principles electronic structure codes, it has become possible to perform large sets of calculations automatically. This is the burgeoning area of high-throughput ab initio computation. Such calculations have been used to create large databases containing the calculated properties of existing and hypothetical materials, many of which have appeared online.
We have released version 1.0 of the OPTIMADE specification, with several databases already providing implementations. A full list is available on the OPTIMADE providers dashboard.
How to cite OPTIMADE
Should you wish to cite the OPTIMADE specification, please use the following:
- Andersen et al, OPTIMADE: an API for exchanging materials data (2021) arXiv:2103.02068
- Andersen et al, The OPTIMADE Specification, 10.5281/zenodo.4195050
All of our work is openly available under the Materials-Consortia organization on GitHub and we welcome all contributions.
We would love to help you create and register your own OPTIMADE API implementations and hear your feedback on the specification.
We meet monthly in the “OPTIMADE” room on Jitsi; everyone is welcome to join the discussion, please feel free to reach out on the mailing list
dev[at]optimade.org to register your interest.
The next meeting will take place on Wednesday May 19th at 14:00 UTC/16:00 CEST
With the support of CECAM, we hold annual workshops to discuss and develop the specification and related ideas. The 2021 workshop will be held virtually between June 7th and June 11th, with sessions accommodating multiple timezones. The workshop advert and sign-up can be found on the CECAM website.
