One object has more than one POI-tag (Hotel Café Restaurant)
Issue: One object has (or should have) more than one POI-tags. Possible situations: * "Hotel Restaurant Xxxx" * "Hotel Café Restaurant Xxxx" * "Café Restaurant Xxxx" * "Hotel Aaaa" and "Restaurant Aaaa" and "Café Aaaa" (same location, same operator, name "Aaaa" is identical for all Objects, but only one Node on OSM). OSM best practice and OSM worst practice: Relation: [type=site] + (building + hotel + restaurant + pub) as members. But, issues, options: * Address is on one node only. Duplicated addresses are error (imo), since an address is (should be) unique. * Name is set on relation only. But now I (as Renderer) cannot Get the name from the relation and Set it to the individual POI’s. Also Validators will complain: "this is a restaurant therefore a name is required". * Name is set on all individual POI-nodes. Which is redundant and (imo) therefore an Error. Hotel + name is tagged on building outline ([building=hotel] + [tourism=hotel] + [name=Hotel Aaaa]). Also (imo) not correct: POI-tags should be set on Address-POI-node. I sometimes search for a POI, look for the address and navigate there without using GPS. Also (some?) Renderers will not render POI-tags on building outline (JOSM). No idea how mkgmap (default) style will handle this. For me [mkgmap:line2poi] does resolve. One POI-node: [tourism=hotel] + [amenity=restaurant]. No option to also Add [amenity=pub] (conflicting tag). Renderer has to decide which POI will be rendered. One POI-node One tag ONLY: OR [tourism=hotel] OR [amenity=restaurant] OR [amenity=pub] OR [amenity=café]. Loss of information! On OSM last Mapper will decide ( <cynical-mode> ): "I use this hotel only as restaurant, therefore: Delete [tourism=hotel] + Set [amenity=restaurant]". As a result: we cannot find our hotel on OSM (except - sometimes - by name). Question (1): Is it possible (for me as Renderer) to Get Name by site_relation? Is it possible to Get address for all POI’s from the one Member having address set? (Although not sure if this would be good practice, since Renderer will now create Duplicated addresses). I suggest (for now) a short answers should be either: "Yes, you can: Read the Manual!", or: "Yes, you can: look at mkgmap default style for an example!", or: "No!". Question(2): If "One POI-node: [tourism=hotel] + [amenity=restaurant]" can mkgmap "DUPLICATE" a Node, so I can Render two POI’s: [hotel] + [restaurant]??? I do believe OsmAnd can do this. For a "DOUBLE-TAGGED-POI" I can search in TWO different Categories: "Accommodation" and "Café and restaurant". But also: OsmAnd can search for an address (by looking at near be addresses). This is no option for Garmin GPS. It might be even better (but I know: hard to implement) if I could Render TWO POI's on slightly different locations (top and below): - (hotel) "Hotel Aaaa" - (restaurant) "Restaurant Aaaa" OsmAnd will Render both POI’s on same location (but also: OsmAnd has an option to show "Accommodation" and/or "Café and restaurant"). -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html
Hi Eric, 1) not sure if all your site relation problems can be solved with the relations style file, if not, please give an example and let us know what is impossible. 2) You can create multiple POI using the continue statement.

Hi Gerd, I don't know if it's impossible. Just don't know how to. But before investing a lot of time, I would like to know if it should be possible. You have already answered that question: "not sure"... Attached an example: Het Wapen van Harmelen_hotel_cafe_restaurant.osm - [addr*] is on one node only (should apply to all) - [name] is redundant on all nodes (to make Osmose happy, if I remember correctly). - [name] is not on relation, which is preferred (imo, redundancy) - [opening_hours] different on different nodes (correct). - [website] is on hotel only, but does apply to all 3 nodes.

I should have guessed that one myself; -) Eric. -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html
Hi Eric, with the current type=site relation I don't see any need to process it. Would be different with the older version where name and other tags were only in the relation. Anyway, a rule in the relations file should allow to transfer the info to the members.
