The NOvel MAterials Discovery (NOMAD) Python package

Project description

pipeline status backend coverage report frontend coverage report

NOMAD is a web-based research data management software for materials science. You find the official project homepage and documentation here NOMAD is used to provide an open service for managing and publish research data of the same name. On-premise installations of NOMAD (Oasis) allow research groups to locally manage data with customized NOMAD version and with their own compute and storage resources.


See also the more detailed contributing guide in the documentation.

There are two forks of this repository, one on GitHUB and one on MPCDF's GitLab.

NOMAD's GitHUB project always contains the current develop branch. It can be used to report issues, fork the project, and to create pull requests. After review, pull requests will be pushed to the GitLab project and merged there. Use the regular GitHUB flow to contribute as an external developer here.

NOMAD's GitLab project at MPCDF is used for the main development activities. It runs all CI/CD pipelines and official deployments. It is openly readable, but requires an MPCDF account for active contributions. If you are a member of the FAIRmat or NOMAD CoE project, contribute here.

Most sub-modules, e.g. NOMAD's parsers, are hosted in individual projects on GitHUB within the nomad-coe organization.
