Gallery lacks the ability, present in art, of fetching a data product based on its product ID. This is useful for example when the full data product needs to be read, of which we have only an art pointer coming from an association.

Given the ability of an art pointer to do the same (i.e. fetch the data product element it points to), I expect this feature to be implementable as well.

Implementation of this needs to await some simplifications coming into canvas and gallery.
