As far as I know, the data's only accessible to researchers.
As far as internationalization goes, frankly I couldn't care less. Call me a brute, but I don't see why we French taxpayers should bankroll research in English. It's certainly impossible to be a decent Medievalist if all you know is modern English, albeit this project also involves technical disciplines like imagery, acoustics etc.
Since there are tons of donations from outside of France, that can pay for these portion.

Gothic cathedrals are, as far as I can tell, quite shockingly modern-like in their nature of being so delicately balanced. I think we would learn more from trying to do as historically-informed repairs as possible. Even though, yes, old buildings tend to be quite the hodgepodge of styles and methods.
