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.

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 Jitsi (join with the room code
OPTIMADE); 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 September 28th 2022 at 14:00 UTC/16:00 CET
With the support of CECAM, we hold annual workshops to discuss and develop the specification and related ideas. The latest 2021 workshop was held virtually between June 7th and June 11th, with sessions accommodating multiple timezones.
OMDI2021: Related to the central OPTIMADE efforts, the Workshop on Ontologies for Materials-Databases Interoperability 2021 was held at Linköping University, Sweden on October 5-7, 2021. To read more about OMDI2021 go to the workshop site or the Linköping University event site.
