Would it also be possible to only include the closed changesets in the extended diffs to make it easier to make QA tools?<br><br>/Jais<br><br><div class="gmail_quote">On Thu, May 3, 2012 at 7:08 PM, Frederik Ramm <span dir="ltr"><<a href="mailto:frederik@remote.org" target="_blank">frederik@remote.org</a>></span> wrote:<br>

After some time of thinking what's needed in order to keep osm2pgsql<br>

Yes, that is an excellent idea and would make processing easier for many use cases. (For some use cases it would be good if the diff contained a "before" and "after" picture - that way you could e.g. have a running count of the road lengths in some place without storing anything locally. But that might then be too voluminous.)<br>
<br>
I used to call this an "augmented diff".<br>
<br>
The beauty of this is that such diffs can be issued by anyone who sets up a server for it; no need to change anything on OSMF servers.<br>
<br>
I had a brief conversation with Roland Olbricht about this who suggested that maybe his Overpass API could be fashioned into producing such diffs but I don't think anybody had really implemented anything.<br>
