Hi, I am interested in analyzing the latest full history dump of OSM for a personal project. I downloaded the Latest Experimental History File (history-2014-09-01.osm.bz2) and I was expecting nodes, ways and relations as described in the documentation (wiki.openstreetmap.org/wiki/Planet.osm/full). I actually found <changeset/> elements at least for the first 4000 objects. Did I miss something? I do not want to scan the entire file (1Tb unzipped) if I downloaded the wrong file! Thank for improving my understanding :-) Daniel |

The wiki page (Planet.osm/full) only mentioned nodes, ways and relations when describing the content of current experimental history files. Changesets are also included and the wiki page has been updated. |
You seem to mix the planet and the history. If you are interested in the planet (the data, i.e. all nodes, ways and relations including their tags) then you downloaded the wrong file and should download from one of the planet mirrors instead (planet-latest.osm.pbf or planet-latest.osm.bz2).
Using the same scheme doesn't necessarily mean that it contains the same elements. A XML scheme just describes the possibly contained elements, therefore it is perfectly valid if the history dump contains elements which aren't contained in the normal planet file.
Yet it is possible that the wiki description is out of date or incomplete. Full history dumps are only occasionally generated and may even differ in their content.
