 ## project
 
-With the Metadata Exchange (MEx) project, the [RKI](https.//www.rki.de) is developing a
-transparency platform for finding metadata on the institute's research activities and
-data.
+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 on a daily basis,
-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.
