getting history for large relation

3

Hi, I need to find the original creator of a large relation. But osm.org always times out and OSM history viewer returns an error. Is there any other way to get the past editors of this object?

(Context: this relation is part of the E2 walking path, but this part is identical with GR5 Vlaanderen, relation 3121667. So it would seem more logical to only map it once, and have relation 3228572 only contain the relation making GR5. But maybe there is some unknown reason they do need to be duplicated - and I'd like to ask the original creator about that)

TL;DR: geozeisig is the user you are looking for (or at least, created version 1 of this relation).

  • I have launched JOSM as java -jar josm-latest.jar --debug to capture the requests as they go across the network
  • downloaded the relation through File-Download Object,
  • selected and tried to load history.
  • JOSM timed out waiting for API to respond - but at least I got the URL from the exception: https://api.openstreetmap.org/api/0.6/relation/3228572/history
  • Downloaded that: wget -O 3228572.osm https://api.openstreetmap.org/api/0.6/relation/3228572/history
  • listed out the relation versions with grep relation < 3228572.osm. First result:

    relation id="3228572" changeset="18039456" timestamp="2013-09-26T06:28:02Z" version="1" visible="true" user="geozeisig" uid="66391"
