@andrea-perego @riccardoAlbertoni My worry was indeed that it is not clear what the meaning of 'primary' and 'alternative' is, basically because it depends entirely on context. There are many examples of situations where things (people, cars etc.) have several identifiers that may be primary in one context and secondary in others (e.g. tax identification, social security numbers). In the case of datasets, @agbeltran argues that  "_the primary identifier would be the identifier for the dataset in the catalogue being considered_"; other people think that the primary identifier should be the one in the catalogue where the dataset was first published. So I think it will be hard to come up with a generally applicable definition of the terms 'primary' and 'secondary/alternative'. 
Having said that, I have no objections to the current formulation "_it is very much application-specific and should be better addressed in application profiles_" as this means we don't have to say anything more about it.
