In order to deal with partial assessments and their extensions, we give a characterization of some measures (such as capacities, belief functions, possibilities) in terms of basic assignments ruled by a general operation ⊕. The notion of coherence introduced by de Finetti in the probabilistic setting is generalized to non additive measures and we study the upper and lower envelopes of all possible extensions.
