OpenStreetMap
Today I accidentally deleted a relation. Comparing an older version (a part extracted from europe.osm.bz2 with osmosis) with the current one in two JOSM windows, I was able to find the relation.
It was (timestamp is wrong):
The recreated one is #6'384
I hope this is alright.

The diary did not like the xml relation below "It was"
Anyway the deleted relation was:
id="5734"
member type="way" ref="23045741" role="outer"
member type="way" ref="23045742" role="inner"
tag k="created_by" v="JOSM"
tag k="type" v="multipolygon"
