</div>This seems hopelessly complicated, the way I've imagined importing<br>
this kind of data (haven't done it myself) and keeping it up to date<br>
is as you say, keeping the node Id / way Id in a local table together<br>
with the version. If the version has changed the next time you want<br>
to update, you leave this hotel out and never touch it again with your<br>
automated scripts. The changed version means that the community has<br>
picked up the maintenance of this place and you don't need to bother<br>
anymore.<br></blockquote></div><br>+1<br>Plus in all likelihood, it won't be very far away and will be probably limited to only a few changes, so finding it shouldn't be a problem.<br><br>Emilie Laffray<br>
