Version

During the lifetime of data, starting with the raw data and ending up in the final scientific product, used for a publication, different versions of a data set may be generated. It is in the decision of the data provider which versions should be archived. In principle, this will always be the final quality controled outcome. But in some cases it might also be usefull to store the raw data or even versions inbetween, e.g. if the processing is complicated or takes some time or if the raw data are a valuable source. In certain cases, it might be usefull to define extra parameters for the raw data, to better differentiate between raw and final. In any case, new parameter must be defined, if the unit is different, e.g. raw data in [counts] and final data in [%].

If a data set is published, it should not be changed or deleted (exceptions are misspellings). In case of new versions the DOI system will allow to refer from a newer version to its older and vice versa. In its best case, this may give the user an overview of the processing history of a data set (comparable to the revision history of articles in Wikipedia).
