+Numeric data without accompanying metadata are useless -- it's really that simple. The very minimum would be axis labels and the information where the data originated from and what they represent (e.g., measurements of a sample with some method or results from some calculations).
+The information available is maximal during data acquisition -- regardless of whether this means experiments or calculations. The real challenge is to reduce the available information to a sensible set of parameters.
+Furthermore, metadata allow processing routines to get a "semantic understanding". This means that the information contained in the metadata needs to be stored and organised in a hierarchical fashion, most probably using key-value stores.
+Metadata should be organised and stored in a way accessible to both, humans and machines. This necessitates a (file) format that is platform-independent and as easy to use as possible.
