Even determining if a facility is applicable to a boat would require the consumer to keep up with all the various boat tags. Having a class hierarchy would enable generic actions for watercraft, even if the data consumer did not understand all the options (e.g. generic watercraft which might be a fishing boat, wave runner, rowboat). makes a lot of sense for me, the old system makes it pretty difficult to keep track of all possible tag combinations.

Which is why I tired to formulate this cirteria. a path is way where a hiker can walk without a ferrata kit and without extensive use of arm muscles See above. What's an extensive use? Experienced climbers will tell you that they do it all by technique instead of muscle power. it means to say you do not hang on your arms for a substantial part of the path. Ladders can and should be mapped separately so they need not to be considered here. Btw most hikers are not experienced climbers. a path should be safely passable without a ferrata kit even in less than optimal weather So we need to delete all paths in high mountains, because they are neither ferratas nor safely passable when icy. no.

[Tagging] areas (eg rocks) underwater and across coastline/water shores
Hi, it is mostly so that an area eg natural=bare_rock does not end at the shoreline but extends some way under the water. Current practice of having it end exactly on the shoreline is both incorrect and a technical complication for mappers. In many cases some of the underwater racks would be easy to map. Similar could apply to many other natural objects: ridges, cliffs and (sand) beaches usualy extend some way below water. In fact mapping cliffs across rivers is the commonly used solution in waterfall mapping. So it would appear straightforward to map such natural features across shore lines both under and above water. How do people think about it? Should we generalise that approach or seek another solutions? What would happen with various renderers and other apps? Should we use underwater/awash tag or prefix?

Having areas end exactly at the waterline seems to be a common reason for mapping mistakes and broken coastlines so I don't see that it would be the easiest solution. Also it is almost never so that the rock would end exactly at the waterline and even if you do not know exactly how far it extends underwater a good guess is still better than inserting wrong information.

Until now, we use different values based on the different cabins/cars/lifts type. Perhaps instead of goods it could be replaced by fork or container or container_for_goods, just enhancing the existing list following the same principle. For routing purposes it would be highly desirable to have tagging valid accross all trasnportation means that are potentially relevant to routing, including and not limitted to ship lines, railways and aerialways.

Al that the node says is somewhere there is a bay called XXX A computer algorythm would probably get it wrong most of the time. Think back to the bays within bays situation. How far along the coast do this bay extend ? Are those two nearby nodes separate bays or overlapping ones ? Most of the time there is very little agreement or hard data about the extents and hierarchy of bay naming. Sources from different countries will make different subdivisions. Great fun with multipolygons and even with perfect tagging and computer algorithm we get approximate results at best.

Hi, the approved and currently active proposal for bridges is not quite clear on this - the older bridge=pontoon was not obsoleted but a new bridge=yes+bridge:structure=floating was introduced with the description A bridge whose load is supported by floating on water, rather than resting on fixed supports. Typically a pontoon bridge. https://wiki.openstreetmap.org/wiki/Proposed_features/Bridge_types Are there floating bridges other than pontoon bridges?

The purpose was not quite clear - not drinking water and other parts were not covered. Should we have bridge:cover ? As long as we're simplifying possible values in bridge=, bridge=low_water_crossing, which is somewhat established but a bit awkward, could theoretically just be marked by a separate tag, maybe flood_prone=yes.

I have tagged those with tunnel=culvert and ford=yes flood_prone might be a little better for both in that I think of a ford as having water more or less perennially covering the crossing, whereas a low water bridge, like a road dipping into an arroyo, is only covered by irregular intervals of high water. the flooding can be more or less frequent. In some places that I have seen the flooding was manmade und thus mostly predictable, bellow a dam. The difference I think is how it will be used for routing, so perhaps both are valid alternatives.

I can see where one might want to reduce speed on one of those to avoid bottoming out or becoming airborne. I think rather that bridge:structure=humpback I'd prefer bridge:geometry=humpback. At least something that conveys shape meaning. For me structure implies the design element that gives a building, bridge, dam, etc. its strength. In the case of the photo that would be masonry arch for structure. +1. Humpback seems mostly to be defined by the aesthetic effect and the potential effect on vehicles; there seems to be a popular Humpback Bridge on Virginia that's a covered truss with a mild humpback. I'd rather not dilute the more or less coherent nature of bridge:structure=, although better that than bridge=. Although tagging it as some sort of highway hazard or condition is not a bad idea either. I was thinking maybe bridge:architecture would cover both bridge:structure and bridge:geometry but I guess it is too late to change?

I am not against it... but enough work around:) Bridge=trestle would be a much clearer candidate to remove from the primary values table.. whoever knows how it got there. What is imho much more important is to decide that the primary bridge values should not be further extended without *very* good reasons and the existing system used as far as possible.

The speed limiting factor on this particular bridge might be that you don't see far enough? But using bridge=humpback to imply a hazard may not be such a good idea, will American tourists be familiar with the dangers of humpback bridges? Instead we could describe the hazards as visibility, bump, dip, and narrow single lane with higher chances of universal usability. We could also use reasonable_max_speed (per vehicle category) or do both.

This meaning of span may not be well known for folks who are not bridge experts and not native english speakers. Perhaps sections or segments could be added in brackets for explanation. I don't see how using bridge=movable constitutes dumb-down tagging; all I've done is move the many different possible values to bridge:movable. I think this is an excellent arrangement, because movable bridges seem to stimulate engineering ingenuity: there are many different types, and I do not feel confident that we can build a comprehensive list of them. In practice, we will need to accept occasional user-defined values for types of movable bridges, but we can't show bridge rendering for an open-ended set of values (bridge=*) because many user-defined values indicate the bridge is not functional. Moving them into this subtag seems like an excellent way to balance tagging expressiveness with usability. agree. Maintaining both bridge=movable and bridge:movable=* has at least one useful side effect, which I documented, for bridge geeks like me (i.e., the people who are probably going to be adding hyper-complicated bridge detail); it lets you tag a formerly or planned movable span that is now fixed in place with bridge:movable=* but not bridge=movable. So you could search for bridge:movable=swing and find both working and fixed swing spans, but a router wouldn't treat the fixed ones as movable. (See here http://en.wikipedia.org/wiki/1993_Big_Bayou_Canot_train_wreck for the relevance of such spans.) This may be too subtle for many people and somewhat against the principle of least surprise. bridge=aqueduct has longstanding usage, but could probably be dispensed with. The fact that the bridge is applied to a canal or waterway tells us it's an aqueduct. (For the same reason, we don't need an explicit tag for footbridges; that's determined by the way crossing it plus restrictions.) The main argument I can think of for retaining it would be drained aqueducts from defunct canals, which there's no *de jure* official way to tag. Any thoughts from frequent waterway/canal mappers? it is probably good to keep that one as I have seen plenty of defunct canals going over aqueducts. bridge=cantilever, trestle, and viaduct form a natural group of some kind. I don't have a single word to easily sum them up, but they all have to do with the way in which multiple spans of the bridge are arranged and supported. Note that as far as I know, in both American and British English, the term viaduct can be applied to both road and railroad bridges; it isn't confined to roads. They can't be parceled into bridge:structure because they conflict with the ability to specify the individual spans (e.g., an arch viaduct), but these would be a good target for moving into a subtag. bridge=viaduct has a lot of existing uses because of renderer support. the trestle is something that doesn't fit into bridge:structure well, but bridge=trestle doesn't describe it terribly well either, so some subtag describing the average width and technical details might be a good idea. bridge=covered has been mentioned now and before as possibly redundant to bridge=yes and covered=yes. I left it in because of this message: http://lists.openstreetmap.org/pipermail/tagging/2013-May/013546.html http://lists.openstreetmap.org/pipermail/tagging/2013-May/013546.html which suggested that a bridge covered over wasn't quite the same thing as a covered bridge. I don't have a strong opinion on changing or keeping it at this point. I would be in favor of keeping that one but the problem is - you can't have covered bridge=movable or aqueduct. I have seen covered aqueducts. As long as we're simplifying possible values in bridge=, bridge=low_water_crossing, which is somewhat established but a bit awkward, could theoretically just be marked by a separate tag, maybe flood_prone=yes. The essential quality we're looking to convey is that the bridge is engineered to spend some time underwater and come out intact. those can also look as culverts and it would be nice to have the same solution whether it is a bridge or a culvert.
