Madame Nadeau, New Brunswick is Canada's only officially bilingual province, and presumably you'll be developing your open data sites in both official languages. Obviously the data is numeric, but the descriptors to the data and the capacity to be able to search would depend on which particular language you use.
My question is framed from this point of view. If there were inter-jurisdictional sharing of data, would you perceive there being any problems in the capacity to do searches? If a Canadian citizen were to attempt a search, using both federal and provincial data, and there wasn't a bilingual capacity to be able to do so, would that be any inhibition to being able to have a successful search?
