A word with a specific economic meaning in English, but often used in the context of museums as a direct translation of words such as the French "valorisation" or Italian "valorizzazione". Probably better translated as "development".
The Oxford English Dictionary1 defines valorisation as the process of fixing a commodity's value or price, or more generally of evaluating or giving validity to something. The French and Italian forms of the words have broader application beyond these contexts: alongside valorisation, their meaning extends to cover development (as in developing an economy), and increasing something's standing or reputation. Consequently, the English concept which seems closest is that of museum development.
