I would like to query all of the existing meta-data on a specific user using Overpass QL. I am new to the format, but I know that this will return all the nodes in a box by a specific user:
node (uid:123456) (lat,long,lat,long); out meta;
And I could run the same command for
way's in order to get a complete data-set. But this will not, as far as I can tell, show me the history of the user's activity, in that I won't be able to see the history of edits and changes, deleted items, etc.: only the stuff in the most recent changesets/versions.
I feel like there must be some command along these lines to accomplish what I want:
[diff:"YYYY-MM-DDTHH:MM:SSZ","YYYY-MM-DDTHH:MM:SSZ"]; ( (uid:123456); ); out body; >; out meta;
But as you can tell by running that here, it doesn't work. Also, if it did work, it wouldn't really do what I want, since it would only tell me the difference between one date and the other, as opposed to a list of all the edits of any sort a person has done/made. So the question is: how can I query all of the meta-data on the activities of a specific user in Open Street Maps? (Doing so within a specific date-range and/or bounding box is a plus but not necessary, if your answer takes neither into account I can implement both features on my own after the fact).
EDIT ----- I was able to get results similar to what I'd like with this:
[out:csv(::type,::id,"name",::lat,::lon,::version,::timestamp,::changeset)] [diff:"2012-08-14T15:00:00Z","2014-08-21T15:00:00Z"]; node (uid:1378531) (46.32701220,11.63249080,46.58063280,12.44677780) out meta qt; rel (uid:1378531) (46.32701220,11.63249080,46.58063280,12.44677780) out meta qt; way (uid:1378531) (46.32701220,11.63249080,46.58063280,12.44677780) out meta qt; >; out meta qt;
But as of yet I am not totally sure if these results have all of the changes, or just the initial version and the latter version of any edited node. Moreover, when I try running it with larger date ranges, the server gives me an empty package. I am not sure how I'm supposed to query when I want something that necessitates more memory. Should I break it into multiple date ranges if the range is more than, say, a month, and then combine the results on my local machine after the fact? (It's not hard to combine CSV files with bash so this is definitely an option...)
Per a comment, I should mention that I do not have the flexibility to download gigabytes of data and parse through them. I need to be able to download only the relevant data.
