http://osm102.openstreetmap.fr/~zorglub/watch/ will work better, this URL
may change to something more stable as it is currently a dev site.


Ypu can be bold and select all schools in a quite big bounding box around

I think a better approach is to add a stable ref:* tag to the OSM objects.

That's the approach we have with most opendata available in France. We add
tags like ref:UAI to schools where this ref comes from an official
directory of schools. Same with ref:FR:RATP for subway stations and
bus_stops in Paris area coming from RATP (Paris public transports).

It also opens linking possibility to external additional data instead of
putting sometime too specialized (and changing) data in OSM itself.
It that aspect, a move toward semantic web would be interesting by adding
reference to external URI(s) directly on OSM objects.
