MEx common
Common library for MEx python projects.
Project
The Metadata Exchange (MEx) project is committed to improve the retrieval of RKI research data and projects. How? By focusing on metadata: instead of providing the actual research data directly, the MEx metadata catalog captures descriptive information about research data and activities. On this basis, we want to make the data FAIR1 so that it can be shared with others.
Via MEx, metadata will be made findable, accessible and shareable, as well as available for further research. The goal is to get an overview of what research data is available, understand its context, and know what needs to be considered for subsequent use.
RKI cooperated with D4L data4life gGmbH for a pilot phase where the vision of a FAIR metadata catalog was explored and concepts and prototypes were developed. The partnership has ended with the successful conclusion of the pilot phase.
After an internal launch, the metadata will also be made publicly available and thus be available to external researchers as well as the interested (professional) public to find research data from the RKI.
For further details, please consult our project page.

Package
The mex-common library is a software development toolkit that is used by multiple
components within the MEx project. It contains utilities for building pipelines like a
common commandline interface, logging and configuration setup. It also provides common
auxiliary connectors that can be used to fetch data from external services and a
re-usable implementation of the MEx metadata schema as pydantic models.
License
This package is licensed under the MIT license. All other software components of the MEx project are open-sourced under the same license as well.
Development
Installation
- install python on your system
- on unix, run
make install - on windows, run
.\mex.bat install

Python release verification
Python release artifacts (source distributions and wheels) published to GitHub Releases are signed keyless using sigstore.
To verify a release artifact manually, download the artifact (e.g. mex_common-<tag>-py3-none-any.whl) and its Sigstore bundle (mex_common-<tag>-py3-none-any.whl.sigstore.json), then run either:
Using sigstore:
sigstore verify identity \
--bundle <path-to-bundle> \
--cert-identity "https://github.com/robert-koch-institut/mex-common/.github/workflows/release.yml@refs/heads/main" \
--cert-oidc-issuer "https://token.actions.githubusercontent.com" \
<path-to-artifact>
Using cosign:
cosign verify-blob \
--bundle <path-to-bundle> \
--certificate-identity "https://github.com/robert-koch-institut/mex-common/.github/workflows/release.yml@refs/heads/main" \
--certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
<path-to-artifact>

FAIR is referencing the so-called FAIR data principles – guidelines to make data Findable, Accessible, Interoperable and Reusable. ↩
