But it's possible to have a pass with no way crossing it (not even an informal footpath) or with multiple ways crossing (a dual carriageway, or parallel highway and railway). How should these cases be handled? no, it is IMHO not possible that a pass has no way that crosses it, otherwise it wouldn't be a pass. In the narrower sense you are correct, but: http://en.wikipedia.org/wiki/Col_de_Bretolet A pass (french: Col) that has no way to either side, but a way over a ridge from the Col de Cou ;-) If there is more then 1 one way I guess you would have to tag all of them. Especially in the U.S., I've seen some dual carriageways with two pass nodes, e.g.: http://osm.org/go/T2U0CV8Ye-?layers=O Maybe natural=pass (or mountain_pass) on a node might be more logical for the feature if you bear in mind that the wiki suggests to tag ele with it. The underlying problem what makes a pass a pass is *very* difficult to answer, e.g. there's a lengthy Wikipedia discussion about it. If a pass is closed due to political differences but there's a way over it, this is an easy one (mountain_pass=yes and access=no). The difficult question: What is generally a way in this regard? If you can travel the pass by car, 4*4, horse, MTB, hiking, via ferrata or extreme sports? If you read the wiki page, it started in 2007 with highway=pass, so you can see that I (and others) basically had roads in mind when I've wrote it (and no one at that time seemed to even mention passes with no way). In practice today, a lot of nodes with mountain_pass=yes are tagged, where you don't see any way nearby (maybe from imports?), and a lot of nodes on hiking trails, roads, etc. So today in OSM a mountain_pass=yes denotes the geographical feature in the wider sense (german: Scharte, Sattel, Joch, ...), not the narrow definition of being a passage on a way.

Some people think it's a good idea to not tag this as an area but using a boundary way / relation. http://wiki.openstreetmap.org/wiki/Multipolygon The multipolygon relation is OpenStreetMap's area data type. Which is - well - just wrong. The closedway is the traditional way of OSMs data type for an area and the multipolygon is the modern way if the traditional model doesn't fit well. Most people in OSM will model e.g. most buildings with a closedway and not with a multipolygon (unless necessary). Both would be possible and both are an area. Are you done being pedantic? Sorry, you've missed the point. Maybe this should better read: The whole nature_reserve as a closedway is broken. Obivously nature_reserve is an area (however you model it). But it's usually an area more the size of germany compared to e.g. the size of a single building (yes, you could endlessly discuss about this statement). So while you're modelling the boundary of the nature_reserve (e.g. using a multipolygon) and you're not using a closedway (which you'll probably never do for a nature_reserve), it *never* get's in the way of landuse, natural, surface or landcover.

So it is really only a shorthand notation to save money on signs and to reduce the clutter of street furniture.

From what I have heard, a coffeehouse in Amsterdam, Holland, now means a place that sells marijuana, not one that sells coffee. It's called a coffee shop[1] and those are available throughout the netherlands. You can buy soft drugs and soft drinks (maybe a coffee) for local consumption, but you'll often won't get any cakes or alike or any alcohol there. But seeking for corner cases throughout the world is probably not the best way to find a good way to tag things.

And, I would suggest a unified flowchart in this case makes life easier than comparing three separate, vague wiki pages, or by doing mental experiments. You are asking for black and white definitions/decisions where there's lot's of room for grey. What about a place that serves limited breakfast in the morning, would classify as a cafe throughout the day, serves full meals only at noon and becomes a bar selling cocktails at night? What you can do is try to find good descriptions so that most people understand what is meant and decide locally how to tag it best. Regardless how fine grained you are doing this, there will always be corner cases where two people will disagree with each other. What you just can't do is find a precise definition that is valid throughout the world and will be doubtless in all possible situations. BTW: The flowchart is using highly subjective language heavily-advertised pseudo-food which is *very* certainly not a good way to find a concensus. Why does it try to offence junk food fans? Oh, and the definition of pseudo food will very certainly differ between people from the western world and people in africa starving right now.

When almost all of the tags are readable, then an incorrect tag like this will just cause problems. In fact , it already has - I did a quick survey of it's use in some areas where I know what's actually there. Some sub-stations are marked with power=station (correct according to the wiki) some with power=substation. I think sub-station and station are both tainted now, unfortunately. I'm not saying this is a good thing, but: a) It doesn't really matter for most mappers. b) It doesn't really matter for almost anyone else ;-) c) The definitions of these tags were done in ~december 2007 probably by germans and the native english speakers didn't even care to correct these definitions till now. Since december 2007 it doesn't seemed to matter for most people how the actual wording is. d) I don't think it's a good idea to change a tag description two years after it was documented, because the wording is slightly wrong for some parts of the english speaking world. Because doing so is an annoyance for anyone involved and the wording will *always* be slightly wrong for someone. Not to mention that a lot of people won't notice/ignore any changes here, as these definitions are old enough in OSM terms. My approach: Stick to the wiki definitions even if you don't like it and go on mapping :-) e) Unless someone develops a nice open power distribution map, this discussion is pretty much pointless and will continue or flare up again endlessly, regardless of what we'll end up with it now. So if you are really interested in fixing this power wording problem, go and develop such a map.

The mappers very often can't find a consensus how to tag stuff. In the end this would probably mean that lot's of mappers annoy a very limited amount of rule writers ;-) I guess this is also a lack of man power. Don't underestimate the amount of time that is needed here. Having the actual usage numbers from e.g. OSMDoc[1] would really help here. Yeah, I was just having a look at tagwatch, which has usage numbers for the few hundred tags that are explicitly referred to in the wiki. Can't see how to get global numbers though - only by continent. I may try and integrate these numbers, but I'm a bit wary of what they mean. (eg, one bulk import of 10,000 nodes with a certain tag should not necessarily count for more than 8,000 nodes created manually by 20 different mappers. True. But I'm not sure if this is an often found problem in this case. BTW: tagwatch has a problem especially with the most used keys, see: http://tagwatch.stoecker.eu/Europe/En/keystats_amenity.html It will stop adding new values to the key list, if there are 300 items already accounted (IIRC due to memory reasons). So these numbers has to be taken with caution. It might be better to think in terms of core tags and specialist tags or something. If something is core, we expect all decent renderers to render it. How do you enforce this with people doing the renderer maintenance in their spare time? ;-) I didn't say enforce! All I'm saying, is you give a list of priorities, like all renderers should support these tags. Just like when you saw what the other renderers are doing, I think programmers would be inspired to implement that kind of list. And obviously certain kinds of tags can be implemented very easily, just with a colour or whatever, while others are harder. With all the stuff we already have, nothing is very easy to implement as adding new stuff will make it harder to read the existing stuff on the map :-) Maybe a top hundred of mostly used, but not rendered tags would be nice. I've started something similiar some time ago, but you'll have to somehow filter out tags that won't be interesting, e.g. created_by will be very often used but usually not rendered on a street map (although osmarender once rendered it). I guess, this filter will look quite different for the different renderers. I think its a much better way to display each renderer maintainer: Look, these are the tags that x, y and z are rendering and you don't. Maybe you've just missed it? And also the other way round: No one else is rendering x=y, maybe this is a bug? Yep. And the one I'm concerned about, renderer X supports tag A, renderer Y supports tag B, yet A is pretty similar to B. The mass of landuse=* and natural=* are pretty haphazard - I don't think any sharp distinctions are being recorded. Maybe as a first step we'll iron out the unintended differences between the renderers. That would already be a huge success! If this is done (and this will take some time and effort) then look at the missing definitions. As mentioned already, the next best step IMHO would be to have the actual usage numbers from OSMDoc. However, it's up to you what you do with your free time :-) Doesn't mean I don't want suggestions! [1] http://osmdoc.com/de/tag/sport/ Is there a way to get a big dump from this?

You cannot fix priorities for other people creating the data or other applications using the data. What is the core for OpenCycleMap is not the same as the core for OpenWaterwayMap, OpenCrimeMap, OpenHikingMap, OpenShopMap, OpenTourismMap, OpenSchoolMap, etc... You are really expecting too much from the rendering side of the project. At least for the OSM based maps I've seen so far, the core of features that a map wants to display is often very similiar: streets, rivers, forest, ... plus some special interest stuff specific to this map. This isn't true for all maps and obviously maps will use different styles (colors, thickness, ...) to display these core features in different ways. However, having a list of features that a lot of other maps are displaying will very certainly help map makers in choosing the things they want to display. I don't see this as a has to be implemented but as a toolbox for mapmakers. Just don't underestimate the amount of time to get such a knowledge. What we need is a clear definition of the tags and this is done by searching a consensus on the wiki and on this list and we see if we succeed or fail with the statistics. We have e.g. lot's of highway=path in the database and no one (except the mapper) really knows what this *exactly* means in a specific case, as there is more than one definition out there. But statistics just can't tell you anything about this semantic. If we don't have a common definition of the tags, we end up with different rendering rules and even worst, with different tagging presets in the editors. The rendering rules doesn't matter a lot in this regard. It only displays a cycleway with a certain color, thickness and such - so it can be recognized as a cycleway. What the mapper wants to describe with highway=cycleway and what a map user understands out of this is basically out of the scope of the map display. So, what we have to do first, if we have to fix priorities, is to improve the definitions of the tags, avoid duplicates or changes in the meaning of the tags one year or two after their creation (e.g. the other thread about cycleway on this ML).
