+description: >-
+    The Rosetta Scientific Input Output library aims at providing easy reading and
+    writing capabilities in Python for a wide range of scientific data formats. Thus
+    providing an entry point to the wide ecosystem of python packages for scientific
+    data analysis and computation, as well as an interoperability between different
+    file formats. Just as the Rosetta stone provided a translation between ancient
+    Egyptian hieroglyphs and ancient Greek. The RosettaSciIO library originates from
+    the HyperSpy project for multi-dimensional data analysis. As HyperSpy is rooted
+    in the electron microscopy community, data formats used by this community are
+    still particularly well represented.
