This is for grouping features that are more or less of the same kind. See<br>
examples.<br>
<br>
No, this is not the same as a site relation. See the respective comment in<br>
my proposal. It is hard to compare to the site relations proposal anyway,<br>
because it is full of contradictions and it lacks valid examples. See my<br>
comments there. Please view my proposal independent of the site relation<br>
proposal. The type=cluster proposal aims for simplicity and usability, and I<br>
hope that we can proceed to real voting at some point.</blockquote></div><br><br><br clear="all">this is quite generic what has advantages (apllicable to everything) and disadvantages (it might often not be clear, to what property the "clustering" refers). I wonder if it wouldn't make more sense to use the approach of islands / archipelago, i.e. have a dedicated, explicit and specific tag for the "combined feature" (e.g. several natural=island/islet can be together in a multipolygon relation which is tagged natural=archipelago).<br><br></div><div class="gmail_extra">In your examples, there could be tags for several lakes:<br>natural=lacustrine_district / lake_district or maybe "series_of_lakes" (didn't find a good English word for "DE:Seengruppe").<br><br></div><div class="gmail_extra">Didn't find a good one neither for DE:Höhlengruppe (maybe just plural "caves"?)<br><br></div><div class="gmail_extra">DE:Felsengruppe could translate to "natural=range_of_rocks"<br></div><div class="gmail_extra">(maybe also the caves could be "range_of_caves"??)<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Cheers,<br>Martin<br></div></div>
