Sounds good. I know there is a lot of interest in this.

As well as the 'unified stop area' proposal there is Oxomoa's proposal  
Public_transport_schema) and the derivative of it which incorporate  
input from others including myself and the professional community. I  
don't think we have got agreement on these different proposals yet - I  
know that there is a trial tagging using Oxomoa's proposal in Germany  
but that they are open to some further tagging adjustment. Others may  
be using other schemes such as the unified stop area.

With reference to Oxomoa's proposal, we now have agreement from him  
for the project to take a copy of his proposal as of the 31st May  
after Nimix's edit to the main wiki and develop it from there with  
suitable acknowledgement. I will make a copy of it to the main wiki if  
that is ok with others where we can work on it further. I know there  
is a concern that it might be getting too complex, so lets discuss it  
and see if we can keep it comprehensive and make it easier to use as  

Can I suggest that we treat this import and any final tagging as a  
separate issue on separate timeline from the NaPTAN import just so  
long as no important information in the NaPTAN DB is lost in the  
process. We can then take the time to get agreement on the new tagging  
and also update the renderers to support the new tagging before  
converting the data.

Sound good, but I am keen to see data for Suffolk soon if possible and  
it would be great to have the whole import completed prior to the  
State of the Map conference where Peter Stoner from Traveline will be  
talking on the Friday.
