MEx model

JSON schema files defining the MEx metadata model.

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 FAIR[^1] 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.

[^1]: FAIR is referencing the so-called FAIR data principles – guidelines to make data Findable, Accessible, Interoperable and Reusable.

Package

Our metadata model is represented as JSON schema in mex/model. There, we defined 1. entities, described by their properties, 2. fields, small objects, that are used as $ref for certain properties, 3. an extension, which contains additional properties, that are not in scope of the JSON schema definition, 4. i18n files, that hold translations of the properties and are to be used in the context of user interfaces and 5. vocabularies, which are used in context of the entities. A more detailed description of the model's context can be found in /docs/index.rst.
