[Tagging] Processing the tags

[A.Pirard.Papou]

HI,

I have successfully written programs processing our tags, but 'm stuck 
on this problem.
Given a node number or a way number, typically a street, what are the 
HTTP queries to send, and what is the algorithm to process the replies, 
to determine  the relation number of which municipality, province, 
country, landuse, whichever polygon, etc... that element is inside?

Thanks for some light,

André.
