Re: [OSM-talk] Proliferation of path vs. footway
Nop A very good way of trying to draw some of the thoughts together - although a very challenging project! Full marks for the effort anyway! I have added a few extra bits and pieces to the wiki page to highlight some more existing tags and practices that probably need to be brought into a consolidation attempt.

The discussion has died down again. Much was said and I even had the impression that there was a little progress in some details. But, as usual, we don't have a result. Therefore I have started a consolidation page in the wiki to collect the problems, use cases and ideas for resolving them. I would like to invite all of you who are interested in working on the matter to contribute your recollection to the page and maybe develop it into a solution proposal that is not a one-man endeavour but well discussed by a group of people. You'll find the start of it here: http://wiki.openstreetmap.org/wiki/Consolidation_footway_cycleway_path Once we have collected the pieces from this discussion, it might be a good idea to invite folks on national mailing lists to join in and contribute their use cases. bye Nop -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/atbrowser ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Then, representatives of each country group could compare notes and thrash out an internationally-acceptable proposal.

Re: [OSM-talk] Proliferation of path vs. footway
So a public footpath which the council has converted into a cycleway (part of a future cycle network if the council ever commit funds to complete their decade old plan) which is segregated in some sections and unsegregated in others is possibly a footway with bicycle=permissive? I think I?ve currently got it tagged as a cycleway with designation=public_footpath (as the public footpath signs are still there, despite the ?upgrade?). Bold formatting below added by me. Ed Yes, I would say so, though I'm not sure of the law on council-designated cycleways. I would guess they aren't true public rights of way for cyclists, and the permission could be removed at any time without the same legal protection that true rights of way have.

Re: [OSM-talk] Proliferation of path vs. footway
Roy Interesting - I'd not looked at that one. I have myself already been confusing the wiki pages for 'designated' and 'designation'. The one that I tend to favour in terms of my own mapping (heavily oriented towards off-road and tights of way in England) is 'designation' http://wiki.openstreetmap.org/wiki/Proposed_features/Designation . This works quite well for me - when used as an expression of formal legal status, together with the existing apparently most common practice in England of using highway=footway/bridleway/byway/track/path/cycleway as the primary tag + foot/bicycle/horse/motorcar=yes/no as a description of the situation on the ground and/or signed + surface= or tracktype= for the actual condition as seen on the ground + access= used only in a limited way to indicate privacy or similar restrictions. I got there by an evolutionary process and it does seem to cover most of what I need. But I would be the first to admit that that doesn't make it right for anyone else or 'right' in any 'absolute' sense. What the use of designation= helped most with was separating out a description of legal/administrative status (mostly derived from publicly available and non-copyright sources developed by highway authorities) from the more usual description of what was 'on the ground' or could be deduced from signage. The latter is of general utility; the more legal stuff is very useful for those of us concerned with rights of way in England and Wales and is also slowly making OSM more useful to local authorities (and others who have their own problems with over-enthusiastic OS licensing). It also adds something to OSM that is NOT on OS maps - as they their recording of rights of way is quite often very out of date and quite often erroneous. Happy mapping anyway!

Re: [OSM-talk] Proliferation of path vs. footway
Jason is technically correct. The use of England/Wales bridleways by cyclists is a lesser right than that held by pedestrians and riders. It was added relatively recently (before, cyclists were not allowed on bridleways under common law) and is subject both to the 'give way to others' rule cited but also is not quite universal as the right of access is a default right from central government that can be overridden by regulations made locally (although I have yet to find an example of this). The reference is the Countryside Act (1968) §30: 1. Any member of the public shall have, as a right of way, the right to ride a bicycle, not being a mechanically propelled vehicle, on any bridleway, but in exercising that right cyclists shall give way to pedestrians and persons on horseback. 2. Subsection (1) above has effect subject to any orders made by a local authority, and to any byelaws. Nevertheless I would myself still tag as foot/horse/bicycle all 'designated' as this is at least the default and the 'give way' rule does not remove the cyclists' right (but how I wish that all bikes had bells and all cyclists USED them!).

Hi Ed 1.

Re: [OSM-talk] Proliferation of path vs. footway
... That is current practice - there is no implication of exclusivity only that a legal right of use exists for a class of users. A restricted byway in England and Wales is for example, foot=designated, horse=designated, bicycle=designated (as there are legal rights for all non-motorised traffic); it is also motorcar=no, motorcycle=no; the condition can be described with either a surface= or a tracktype= tag. It should be signed (and mostly is at the moment at each end as it is a very new legal category and the signs have yet to be wrecked) but I wouldn't bother to add signed= as it does not give the user much in the way of additional information once they know it is a restricted byway. The question that is currently the main subject of debate in this thread seems to be the primary one as to the type of highway. Should it be highway=restricted_byway, highway=byway, highway=track, highway=path ... I would currently use the first of these as being the most specific (and, yes, it is documented on the wiki) - but I appreciate that there are ambiguities that are being discussed in the thread.

In England, tag with highway=path (or track); foot=designated. In Norway, tag with highway=path (or track); foot=designated; bicycle=designated. This doesn't sound quite right to me. If it is signed as a footway in Norway (picture of a pedestrian only, no bike [1]), it is sometimes allowed to cycle there, but only if there are not too many pedestrians and only at walking speed. Sorry, my comment was based on someone saying that in Norway, bikes could use footpaths, and me assuming it was a full legal right. This does make things a bit more difficult as I have not come across these sorts of in between rights before. However I'm not sure that highway=footway is the answer. Someone should ideally not need knowledge of local laws: as someone from the UK I can instantly tell that I'm not supposed to walk on German bridleways (see another message) if they are tagged with the generic, international tags of foot=no; horse=designated; bicycle=no. Likewise someone from Germany, say, can instantly tell that they can walk, or cycle, on a UK bridleway. yes, if you would tag foot=yes, but I guess you usually never did this, because you thought everybody would know that you could walk there. so it comes down to the general observation, that different countries have different defaults, and how to deal with it. There are 2 main possibilities: 1. tag on every single way all worldwide thinkable keys 2. document the implicit defaults somewhere in a standardized form, be it wiki or database of course, there would also be 3. don't document and refer to local legislation. Therefore it should be clear how to express local traffic signs in an unambigous way into tags. and 4. do 2 in an non-standardized form but 3 and 4 are not very reliable and practical, e.g. if you wanted to make a router that works worldwide it would be too timeconsuming to get all the rules. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I would similarly guess the shared foot/cycleways in Germany would be similar, i.e. foot=designated; bicycle=designated. Nick After looking at the British Ramblers Association website today it does not appear cyclists have equal rights on Bridelways. This website give advice on access rights to footpaths etc in the UK, and it says Pedal cyclists have a right to use bridleways, restricted byways and byways open to all traffic, but on bridleways they must give way to walkers and riders. Like horse riders, they have no right to use footpaths and if they do so they are committing a trespass against the owner of the land, unless use is by permission (see Q26http://www.ramblers.org.uk/info/britain/footpathlaw/footpathlaw2.htm#trespass). As with horse-riding (see Q10http://www.ramblers.org.uk/info/britain/footpathlaw/footpathlaw.htm#horses), use of any right of way by cyclists can be controlled by traffic regulation orders and byelaws imposed by local authorities. Infringement of byelaws or orders is a criminal offence. Under the Highways Act 1835, it is an offence to ride a bicycle on the pavement at the side of a road, and under the Fixed Penalty Offences Order 1999 a person who rides on a pavement can be fined on the spot by a police officer.

Re: [OSM-talk] Proliferation of path vs. footway
I'm afraid I have just been completely overwhelmed by this thread and the other similar ones over the last couple of weeks while trying to have a life too. I am also conscious that it is a discussion that reignites in different guises every few months. I apologise if I'm repeating what's already been said. How do you know what is legal vs conventional? Except if you are in a privileged position, it can only be from evidence on the ground, in which case what would you do different in most cases? Would you mark something as a cycleway where cycling (or whatever) is happening but not legal (as evidenced by the signage and knowledge of the relevant rules)? Or not for cycles when the evidence shows that it is intended so? I think this legal stuff is a red herring (English idiom: a distraction) except in certain special cases. My feeling is that what we are missing is largely country-specific defaults. Or rather we have failed to recognise this in the documentation, but it is what pretty much everyone is doing in practice already, and that's got a lot going for it. What most people are doing now and will likely continue to do is seeing something on the ground which says I am a cycleway by whatever system or evidence is relevant to their location, knowledge of local laws and rules of the road etc, and therefore tagging it highway=cycleway. The same applies to motorway, footway etc. What a user of the map understands is the same thing, because they know that cycleways or footways can or cannot be used by pedestrians or cyclists respectively, or that motorways can or cannot be used by farm vehicles, or whatever in that particular country. When we have exceptions, again the common practice is for people to indicate them. Hence a weight limit or a time restriction. So my feeling is we should document what collection of users a particular highway tag applies to by default IN EACH COUNTRY (including things like under 12 or not on a Sunday if that's the normal situation). Then tags and renderings mean what ordinary people (users and mappers) expect them to mean. If a particular footway is specifically open to cyclists, for example a permissive path that someone quoted, then if the local rules are that pedestrians can use cycleways, it makes no functional difference whether it is marked as a footway where cycling is permitted (by whatever tagging convention) or as a cycleway. You might choose to do one or the other based on a subjective judgement about the principal use, so it might affect how it is drawn but should not affect routers looking for both bicycle=yes exceptions and highway=x where x has defaults for that location which include bicycles. I don't see that deviations from the normal rules for types of transport are different in concept from other exceptions like weight or time limits. -- So I say: keep it simple, keep it compatible. Carry on with the simple, established tags we already have, but just clarify the default use classes which apply to each highway tag, PER COUNTRY, and tag exceptions to these according to evidence on the ground. Add specific legal designations only where expert knowledge is available and different from the default interpretation. --- I think the same principle applies to speed limits (motorway 70mph, trunk 60mph in UK, unlimited and whatever km/h in Germany etc), weight limits and so on.

Among data users there is a strong preference for tag combinations to be hierarchical, and I think that preference is reasonable. While having to deal with doctor and doctors is only a mild pain, trying to deal with multiple overlapping fuzzy definitions for commonly-used tags is enough to make your head spin. So - path should either pitch itself to cover everything (ie footway should be a subset of path), or to cover a clear niche (ie path should be independent or a subset of footway). The deprecation of footway/cycleway was voted on (by not many people, but nevertheless), and the deprecation was rejected, but some people don't seem to be able to take no for an answer. You can use the same analysis for footway/cycleway. Either one is a subset of the other, or they should be clearly independent. The wiki tries to make them independent (mainly or exclusively), but they aren't in many countries, hence the confusion. I think treating cycleway as a subset of footway is a more robust model, allowing the grey area between the two to be described more accurately, rather than trying to pretend it doesn't exist.

The information is useful, but the current concept of OSM tagging is not designed to deal with it in a systematic manner. Can you expand on separate namespace? Without a full new proposal, the current concept of OSM tagging is all we have to work with right now, and the issue is choosing appropriate tags and tagging schemes. Which do you think more appropriately separates legal issues from geographical map features, the highway=path or highway=footway/cycleway scheme? Sure. By namespace I mean something like the Karlsruhe meeting introduced with the addr:* family of tags. In this example, addr would be the namespace. My experience with OSM is too short (I'm a newbie :-)) to actually come up with a proposal on how to separate out the judicial circumstances from the map features; I suppose a tag family called law:* would be appropriate on highways to specify trafic rules (including whether you can travel by foot on a cycleway). Following the thought of namespaces, the classical geographical features might be transitioned to a geo:* namespace.

2009/8/13 David Earl da...@frankieandshadow.com: How do you know what is legal vs conventional? Except if you are in a privileged position, it can only be from evidence on the ground, in which case what would you do different in most cases? I don't think it requires a privileged position in a democratic country to get this kind of information, but it might be easier and faster if you are in it. You could check your local town council announcements (they are a usable source, as the have law-like nature and are therefore not protected by copyright) or similar stuff that deals with this topic. Would you mark something as a cycleway where cycling (or whatever) is happening but not legal (as evidenced by the signage and knowledge of the relevant rules)? no, but I'm actually tagging it as bicycle=yes because it is tolerated (and there is no fine). Or not for cycles when the evidence shows that it is intended so? I think this legal stuff is a red herring (English idiom: a distraction) except in certain special cases. My feeling is that what we are missing is largely country-specific defaults. Or rather we have failed to recognise this in the documentation, but it is what pretty much everyone is doing in practice already, and that's got a lot going for it. yes, it simply is not documented (yet). When we have exceptions, again the common practice is for people to indicate them. Hence a weight limit or a time restriction. +1 So my feeling is we should document what collection of users a particular highway tag applies to by default IN EACH COUNTRY (including things like under 12 or not on a Sunday if that's the normal situation). Then tags and renderings mean what ordinary people (users and mappers) expect them to mean. +1 If a particular footway is specifically open to cyclists, for example a permissive path that someone quoted, then if the local rules are that pedestrians can use cycleways, it makes no functional difference whether it is marked as a footway where cycling is permitted (by whatever tagging convention) or as a cycleway. you're wrong. It makes a difference on how the cyclist can go (implicit maxspeed) and it makes a difference for the pedestrian who can not legally use a cycleway. So I say: keep it simple, keep it compatible. Carry on with the simple, established tags we already have, but just clarify the default use classes which apply to each highway tag, PER COUNTRY, and tag exceptions to these according to evidence on the ground. +1 Add specific legal designations only where expert knowledge is available and different from the default interpretation. why? It doesn't harm and serves in cases of ambiguity. I think the same principle applies to speed limits (motorway 70mph, trunk 60mph in UK, unlimited and whatever km/h in Germany etc), weight limits and so on. actually we put maxspeed on all highways in Rome from unclassified upwards, even when it is just implicit, and invented a tag to indicate that the maxspeed is not explicit. We add a key maxspeed=50 and maxspeedtype=ITA:city In the unlikely case that the general maxspeed in Italian towns is changed, we can change those maxspeeds that are implicit ones automatically. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

In other words the assumption is that the owner of the path/land does not mind cyclists using it. Then, if it turns out that they do mind, we can change it to bicycle=no. I would apply a similar approach to paths too. I have no idea of exactly what the German law is on this, but when I was in the Schwarzwald last month, the paths/tracks in the forest were either waymarked by yellow/red/blue diamonds, or not waymarked at all (apart from the occasional Betreten verboten). I have not got round to marking these up yet, but my intention (German users, please feel free to tell me otherwise!) would be to tag the waymarked paths as highway=path|track; foot=designated and the unwaymarked tracks as highway=track; foot=permissive if I saw evidence of use e.g. someone walking along one, or simply highway=track if I literally didn't know whether the track was OK to use or not.

Re: [OSM-talk] Proliferation of path vs. footway
In my opinion, suitability is a whole new topic that should'nt be represented by *mode_of_transport*=yes/no, as it's highly subjective. yes/no should solely describe the legal status. Agreed. One can use the surface tag to do this together with SAC_scale etc (with which I'm not 100% familiar but do understand the general purpose of) So bicycle=designated; surface=rock; highway=path for some of the bridleways you get in upland areas would indicate that bikes have a legal right to use it, but might not want to.

In practice you probably wouldn't do it in the routing software itself, but when transforming the data from OSM format to whatever the router uses.

To some extent we are relying on similar traffic laws in enough countries to declare a default, and to expect places where those defaults are not true to tag as exceptions. Except it's plainly impossible that someone is going to be able to make defaults for the entire world, and certainly no defaults that the entire world would be happy with. A large number of tags are already dependent on the country they're used in anyway. So trying to come up with global defaults doesn't make sense anymore, and will certainly make people in some countries unhappy if they suddenly have to add several tags to each way where those tags used to be implied, because suddenly global defaults were introduced. And global defaults immediately break down at step one: defining vehicle classes. Those are just different in each country, and simply can't be merged. The concern is also that: (a) traffic code changes over time, so what's allowed today maybe wouldn't next year, even though the signs would stay the same, so we have to map in a way that we don't have to retag all roads if it does change (or worse: revisit each road because we don't have a method to know what was on the road) (b) mappers don't exactly know the entire traffic code either so they wouldn't know of certain exceptions or rules, they can see the traffic signs though so it makes sense to have tags that somehow relate to those signs in an understandable way I'm not saying we have to use traffic_sign=C9:M2 or something, but a tag that more or less says what's on the sign (like motorcar=no when it's a prohibition sign with the icon of a car), even when it's not just motorcars that are prohibited there, but all motorized vehicles with more than two wheels, like motorcycles with a sidecar. In the case of cycleway, the global norm seems to be that pedestrians are permitted. But we have to do either define a default for each jurisdiction AND encode the default in the map with polygons OR have some table for renderers) OR define a global default AND tag all ways with exceptions to the global default It definitely has to be define a default for each jurisdiction AND have some table (a library or whatever) for programs that need to know the rules But making that table will certainly not be an easy task... And table may be a bad word here, it would probably have to be something rule based, with for example conditional tests on certain tags, as one tag won't be enough to know access rules of all vehicles. With highway=path, the wiki page does not give the semantics when there are no tags. For highway=path and no tags, is that horse=yes or horse=no? I can only say how it's for Belgium: on a highway=path these vehicles are allowed unless there are other tags: * foot * bicycle * horse * moped_A * moped_B (those last two are subclasses of moped) Is it paved or not if there is no tag? It's just unknown if there's no tag. Is a default really needed for surface? The biggest problem is that there needs to be an unambiguous mapping From these highway=foo tags to the implied value of the access subtags. The next biggest is non-operational semi-circular definitions like 'highway=cycleway' being for 'designated cycleways' which talk about 'intent', although in practice one would ask (in en_US) do most people think this is a bike path. Can't agree more. I've done some work towards it for Belgium here http://wiki.openstreetmap.org/wiki/User:Eimai/Belgian_Roads#Paths Note how cycleway/footway/bridleway are only used for paths with the round blue signs. Maybe we'll end up with a definition of bridleway, cycleway and footway in terms of path, with the notion that cycleway and footway are paved, and path is unpaved if not otherwise tagged. There's really no need to define cycle/foot/bridleway in terms of path. They can have their own special use. Many legislations will have their notion of a cycleway, footway or bridleway, and they'll have their implications in terms of access rules (not necessarily on the path only, but as well on the adjacent road for example), who has to give way to whom etc. So it makes sense to align those definitions with the usage in OSM.

I don't think there is any such thing as a generic trail. I think highway=path should simply imply that the way is a physical route used for travel but not suitable for cars. Additional tags seem to be necessary to describe details, if available. Then why don't we use just 'highway=road' for any physical route that is suitable for cars? With your reasoning highway=motorway, highway=trunk, highway=residental, etc. are unnecessary, as the properties can be described with other tags… But we have the another layer of abstraction and I think it proved useful. We could define motorway by its surface, width, number of lanes, vehicles which are allowed and which are not, but this does not make things simple and would make interpretation of the map very hard. Classifying ways into motorways/primary/secondary/residental makes things simpler. The same should be true for ways useful or dedicated for pedestrians and cyclists. IMHO path should be the same thing for foot/cycleways what a 'track' is for 4-wheel vehicles. Higher-level ways should be tagged as footway/cycleway/pedestrian.

Anyway, something that is not meant for car traffic. I would believe that majority of people would be satisfied if they just knew if they are allowed to walk or cycle along that way/track/path. This need could be satisfied with two toggle switches and four resulting combinations: walking=yes/cycling=yes, walking=yes/cycling=no, walking=no/cycling=yes, walking=no/cycling=no. This information would be enough for me at least when walking or cycling in a city. Other information that would be useful for more advanced and sophisticated use could be given with additional tags.

I think we are at a turning point now. Up to now, we could get away with changing existing tags, but as people start to use OSM for real world tasks and base software on it that is outside the OSM community, like other file formats, we really have to be more controlled about upward compatibility and support. People won't use OSM if we keep changing it in unexpected ways under their feet. We may realise we made a mistake doing something on way and not another, but we have to take into account the impact and cost of changes against the perceived problem something causes. For example, changing highway=gate to barrier=gate. That allowed for a consistent way of presenting barriers, but at the expense of anyone relying on gates to block routing through them for example not working (and if they weren't aware of the change - why should they be? - theior programs stopped being effective). This was a largely cosmetic change, a change for tidiness sake, not because it was necessary. Changing the common tags like footway/path or the main highway designations would be a disaster for these reasons. Consumers (people and software) want to have confidence in what we provide. They are worried about that from the point of view of people adding incorrect map data or not having complete map data, and breaking their software because of an arbitrary incompatible change adds to this.

As with car access on very rough tracks: there could be tens of tags to describe the ground clearance, wheel size and suspension travel etc. required to get through, but instisting people start measuring them is too much work that anyone else would start doing so - users require something simplified from that - even if there's no widely accepted solution yet. The description of a way for other users than cars varies on multiple axes and fitting all that into one tag seems impossible; yet it's most of the time reasonable and simple to divide the decision space into two sets: cycleway and footway and use additional tags from there on. Some ways then are borderline cases or sufficiently outside of those two sets that they necessitate some other solution. Most of the time the intended use is unambiguous, either signedposted or evident from the location or structure. Where it's not, I trust people can classify things on a closed scale, even if with some personal judgement And to make those cases easier, there is a need for something in addition to the footway/cycleway pair. (Where does a coniferous forest turn into a mixed forest? One birch? One birch for every ten pinetrees? 25:75 distribution?) Much of the discussion would have been avoided if the documentation of footway and cycleway had been more exact already in the fall 2007 - it took me then quite a lot of reading to get to the logic and implications behind them, and many don't read that much of the scattered documentation which has lead to some of the pages having been changed around and misconceptions. The big question is just how can that be fixed? Alv ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Proliferation of path vs. footway
2009/8/11 David Earl da...@frankieandshadow.com 2009/8/11 Frederik Ramm frede...@remote.org mailto:frede...@remote.org On the other hand, if your desire is to change something that already exists and ask people to tag it differently from now on, or even worse if you want people to agree on a blanket automatic change of millions of existing objects, then you'll have a much harder time convincing people that this is required. I think we are at a turning point now. Up to now, we could get away with changing existing tags, but as people start to use OSM for real world tasks and base software on it that is outside the OSM community, like other file formats, we really have to be more controlled about upward compatibility and support. People won't use OSM if we keep changing it in unexpected ways under their feet. We may realise we made a mistake doing something on way and not another, but we have to take into account the impact and cost of changes against the perceived problem something causes. For example, changing highway=gate to barrier=gate. That allowed for a consistent way of presenting barriers, but at the expense of anyone relying on gates to block routing through them for example not working (and if they weren't aware of the change - why should they be? - theior programs stopped being effective). This was a largely cosmetic change, a change for tidiness sake, not because it was necessary. Changing the common tags like footway/path or the main highway designations would be a disaster for these reasons. Consumers (people and software) want to have confidence in what we provide. They are worried about that from the point of view of people adding incorrect map data or not having complete map data, and breaking their software because of an arbitrary incompatible change adds to this. We need to live with our quirks, poor choices and so on more as time moves on. I agree. We are starting to see people using OpenStreetMap data and they are now expecting some relatively well defined tags (minus the fuzzy definition for some). I am myself in that position. I am not sure I want to spend hours and hours to rewrite programs that are using some already defined scheme. We have to live with it, and to agree on the basic definition. There were some talks on agreeing on a definition, and I strongly believe that we should start here. While the current system may seem simple, I think it solves most, if not all problems. We are starting to split hairs in an impressive number of ways (and I won't even talk about the number nodes underpinning those ways). I understand that we want to reach some kind of perfection but as we say in France (in a very rough translation), the better is the enemy of good. In addition, there is a time where we have to decide to go with a system even if we know it is partially flawed. If it was an IT project, we would have gone over budget so many times that I would be scared to show my face to my bosses. I am not saying that we should compare OSM to an IT project, but we have to consider that there is currently an ecosystem out there using OSM with its current assumption and that if we keep changing things, we will lose people as it is a mess. After all, one of the rule of the Linux kernel is not to change any ABI. Once it is there, it stays there as it may break applications depending on that interface. As Frederik clearly stated and very rightfully, if your new tag is solving a new problem that nobody got before, no one will be complaining about it. We should stop reinventing the wheel. Let's work on those definitions first to make sure that everyone and every languages are on the same wavelength. In addition, I strongly believe that committees in a semi chaotic project are useless. I don't think the foundation should be involved in any of the tags decision. The foundation is not here to decide on the content.
