[OSM-dev] node/way/relation IDs

[Bernhard R. Fischer]

Hi!

I am working on Smrender (http://www.abenteuerland.at/smrender/), a renderer 
for paper charts. It creates an in-memory database for rendering and I use the 
object IDs as keys.

Do nodes, ways, and relations share a common pool of IDs (i.e. there is no 
node which has the same ID as a way), or do those object have separate ID 
pools (i.e. there may be a node which has the same ID as a way)?

I already tried to find an answer in the Internet but didn't find one yet.

Best regards,
Bernhard
