Welcome to the list, and I assume that you products in France are  
referenced back to Transmodel so we can have confidence that what you  
call a Stop Point and a Stop Area is what I mean by the same term.

I am pleased to say that we have a growing group of people from the  
professional community on this list now and that this includes a  
number of people who helped define the CEN standards themselves. I  
worked on the NaPTAN - definition of bus stops etc (UK), TransXchange  
- exchange of schedules (UK), SIRI  -  exchange of real time PT  
information (CEN) and also passively involved in IFOPT - complex  
interchange standard (CEN). We also have Joe Hughes (Google Transit  
and GTFS), Roger Slevin (DfT/Traveline/CEN), Peter Stoner (Traveline)  
and Nick Knowles (author of many of the CEN standards) - Nick has  
updated the NaPTAN wiki page in the past few days and will probably  
announce himself soon. It would be good to have people from other  
counties as well participating, but the list is doing very well indeed.

In relation to your project I assume you are aware of some of these  
other projects that are happening around the world?

I don't see this as a reason not to get stuck into the subject, far  
from it. There are lots of players, but also lots of work still to be  
done. Lets use this list to ensure that there is a good workable link  
between the physical infrastructure (OSM core activity) and the  
schedules (OTT/GTFS etc).

Our challenge within OSM is to get all this knowledge, effort and  
commitment turned into a usable and functional set of simple tags. I  
love the way people are collecting photos of bus stop flags from all  
over the UK to compare with the NaPTAN data, it is this level of  
detailed attention that is going to take this project to some very  
interesting places.


Regards,


Peter
