Hi,

Thanks for the feedback.

@Giancarlo, can we consider these papers to be an anser to your action-202 (https://www.w3.org/2013/dwbp/track/actions/202)?

@Riccardo, in fact I understand that according to ISO 'measure' would be worse than 'measurement', as for them the measure is abstract, and the measurement is concrete, so closer to what we currently call 'measure' in DQV (and what Datacube calls observation).

@all: re. coming back to 'observation' for DQV, I now count 2 against, 1 in favour ;-)

Antoine

For example in French the noun 'mesure' can mean both the metric (in a mathematical sense) and the result of the action of measuring. Maybe English speakers would rather call the latter a 'measurement', (even though the boundaries for this noun are also not very clear in English either).
