+FAIR data + privacy metric evaluation algos.
+Dataset offers some schema.
+Privacy metric requires some set of features.
+**Case 1**
+dataset schema = required features by privacy metric
+**Case 2**
+dataset schema $\subset$ required features ->
+_2.1:_ feature extraction algo(s) exists, which can computed missing features
+_2.2:_ missing features CANNOT be computed form available schema/data
+**Case 3**
+dataset schema $\supset$ required features -> project schema down into relevant feature space/ leave out uneeded data
+**Case 4**
+Unknown relationship -> further investigaton needed 
+Is this realistic case?
