[OSM-dev] Changeset discussions: dumps and replication

at the recent Karlsruhe hack weekend  (thanks to Geofabrik for
hosting), Paul Norman and i made some changes to changeset replication
 and planet dumps  to support discussions.
the first of the dumps is now available  as, for the moment, a
separate file and the plan is to merge that back into the "main"
changesets dump in about 6 months time - if you consume changeset
dumps, please test your code against the discussions dump!
the discussions dump is largely the same as the changesets dump, but
includes the discussions like this:
<changeset id="1" created_at="2005-04-09T19:54:13Z"
closed_at="2005-04-09T20:54:39Z" open="false" user="Steve" uid="1"
min_lat="51.5288506" min_lon="-0.1465242" max_lat="51.5288620"
max_lon="-0.1464925" num_changes="2" comments_count="1">
<comment uid="33757" user="Minh Nguyen" date="2014-11-15T11:43:09Z">
<text>From humble beginnings…</text>
which is the same format as the API (with comments included) .
these are also present in the same format in the changeset replication
feed , which allows you to keep a dump or replicated database up to
date with the latest comments & changesets.
i hope this will give everyone the data they need to build interesting
new ways of visualising and interacting with the changeset comment
data, for example; better UIs to display discussions near me or on the
map, analysis tools to check for spam or other bad comments, and
entirely new and unexpected cool things.
cheers & happy hacking,
