[OSM-talk] Number of Edits Take 2
I've written a script to estimate the number of names added by each user.
Currently it just looks at who did the last edit on each object with a name.
Once again it may allow us to spot errors like mass imports gone bad.
Below are the results for 20 August. I'd say that anything above 2 is
most likely not the surveying work of a single human since the project has
started and involve some copyleft material.

awk '/.*id.*timestamp.*/ { sub (/.*id.*timestamp.*user/, ); sub(/ *.*|
*lat.*lon.*.*/, ); uname = $0};/tag k=.?name.* v=.*/ {print uname}'

Brett Henderson wrote: Would this mean you'd update the same way multiple times within a single revision? I'm nervous about what this means for replication. How does osmosis know when the way is complete and ready to be replicated? Sorry, probably off topic here but just keep it in mind. Not quite sure what you mean. 0.6 transactions will just be (AIUI) groups of edits, nothing more. There is no suggestion that a set of edits should be considered incomplete just because the transaction is still open. Transactions will simply allows us to rollback a group of edits in one hit. At present, if way 2342341 contains node 645678 and you move said node, Potlatch will write a new revision of 2342341 - partly to give the 'created_by' for that user/timestamp, because Potlatch doesn't write created_by on nodes. All that will change with 0.6 is that Potlatch will no longer need to revise 2342341, because the created_by information (and possibly other metadata) will be in the transaction. Follow-ups to dev, probably. cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I know that mikes has imported loads of boundaries in Germany, and I suspect that LA2 has also imported coastlines. The others, I have no clue. Interesting to find katpatuka in this list. Last I know, he was editing roads in and around Turkey from Y! imagery. Would changing tags on long ways (say, a coastline) count as one change?

Regards, Hakan I suspect in his case some of the edits probably came from using the Lakewalker plugin, which by default splits the traces into 250 node ways. So if the coastline was traced then uploaded then edited and uploaded again, it wouldn't be hard to quickly add up to a lot of edits. -Jason Reid ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

No. It always writes a new revision of the way (I'd anticipate this changing in 0.6) but nodes are only updated when they've moved/been retagged. cheers Richard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
