But I certainly had in mind that it would be useful for some interesting analysis like what you have in mind. Off the top, I can say there are just over 700 unique key values used in tagging changesets. Some of them are obvious errors, some of them are actually interesting. There are 630,000 changesets with no changes in them. Didn't P1 create a changeset as soon as it was fired up, even if no changes were made? There are 239 changesets with 50,0001 objects. Off-by-one error in the API? :) And that's just the first few things that came to mind. I haven't had much time to get into the data yet. Heck, I'm still working on processing my survey data from Christmas :/ Toby ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Re: [OSM-dev] Using changesets-latest.osm
I present ChangesetMD: https://github.com/ToeBee/ChangesetMD As noted in the readme, this is my first real python so I can't guarantee it won't try to erase your hard drive although this seems kind of unlikely :) Right now I have indexes on tag key/values and user name. Depending on what you are querying on, others might be called for. I'll see what happens when I start playing with the data.

But whatever. It's not like parsing XML is hard. I can write something to do what I need pretty quickly. Osmosis doesn't support XML changeset records in OSM files. It supports the changeset id attribute on entities and will create dummy changeset records in the database to satisfy referential integrity, but all the metadata associated with a changeset is ignored. If you process a file with only changeset records then no processing will occur. Brett ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Pardon the question but you *are* aware that changesets-latest.osm.bz2 does only contain changeset metadata, not the actual information on *which* objects have been changed in each changeset? Therefore, while importing that into an apidb schema is perhaps not completely useless, it is of limited use.
