Some of the recent patches to JOSMs default preset have included <preset_link /> elements for what are essentially presets for "similar" objects.
Example: 5211 <item name="Antenna" icon="presets/tower/antenna.svg" type="node,closedway" preset_name_label="true"> 5212 <link wiki="Tag:man_made=antenna" /> 5213 <space /> 5214 <key key="man_made" value="antenna" /> 5215 <optional> 5216 <reference ref="name_ref_operator" /> 5217 <text key="height" text="Height (meters)" length="7" /> 5218 <text key="ele" text="Elevation (meters)" length="10" /> 5219 <combo key="material" text="Material" values="adobe,brick,concrete,glass,masonry,metal,plastic,reinforced_concrete,steel,stone,wood" /> 5220 <reference ref="communication" /> 5221 </optional> 5222 <preset_link preset_name="Mast" text="Similar but different tags:" /> 5223 <preset_link preset_name="Tower" text="Similar but different tags:" /> 5224 <preset_link preset_name="Big Communication Tower" text="Similar but different tags:" /> 5225 <preset_link preset_name="Telescope" text="Similar but different tags:" /> 5226 </item> <!-- Antenna --> This would seem to be to me quite interesting information to capture, however the specific unstructured way of handling this would seem to be a bit sub-optimal. In particular this makes it difficult to present this in a reasonable fashion without restoring to ad hoc hacks. In the hope (though very very very small) that JOSM might some time in the future adapt an extension to support this better, before I implement this (see http://vespucci.io/tutorials/presets/#extensions for other extensions), I'm soliciting input on the preferred way to do this: - add an attribute to the preset_link element, example <preset_link preset_name="Mast" alternative="true" /> - introduce a new element, example <alternative preset_name="Mast" /> - introduce a new element as a container, example <alternatives> <preset_link preset_name="Mast" /> <preset_link preset_name="Tower" /> <preset_link preset_name="Big Communication Tower" /> <preset_link preset_name="Telescope" /> </alternatives> In any case I will add this to the xslt transforms to re-create a JOSM compatible variant of https://github.com/simonpoole/beautified-JOSM-preset as I currently do, so this wouldn't create an incompatibility with use in JOSM.
