+# Musical Manuscripts Metadata Readme
+
+This Readme offers explanations for all attributes of the metadata ``.csv`` table to the dataset “Musical Manuscripts.”
+The frequency attribute can have the value "all", "most", "some" or "none". It gives you an overview of how often a value is to be expected for the attribute explained in relation to the whole dataset.
+The CSV is an export of keys and values of the ONB catalogue system. Some values may have a false attribution. Some data cleaning may be necessary. The exemplary data instance was taken from the full metadata ``.csv`` table.
