I recall the very early discussions and the first draft of Map Features that we said it really didn't matter too hoots whether it was yes/true/1 as there was enough understanding in the value to know what it meant. I'm still tagging most stuff with true and I can't give a reason why. I'm not even remotely coding orientated so why I should have picked true/false over yes/no I cannot say. I don't much care either. I'm generally in the standards rather than the anarchist camp, but I don't care what things are called. I'm just as happy with true, yes or 1 in this case. The problem here is that most of the tools are the opposite, so chances are these changes are pointless and will tend to drift back again over time. I'd still like to see a middle ground where tags can be added and amended at will but through a schema of some kind so the current position is documented and can be checked. But that's not what I was getting at here. But like you, the time making the change is wasted. Far more productive to go and map something. My point exactly.

[OSM-talk] oneway yes or true
I think that the important issue here is respect for others' edits. Personally I only use true/false 0/1 when coding computer programs. In real life I think that yes/no is much better.

Anyone can tag anything any way they like, but it helps to follow the commonly accepted tags (such as those listed in the wiki, as well as probably many that are widely used that haven't made it there yet) so that other software can render meaningful maps from it. And it isn't just on the basis of personal preference. As sly wrote on this list recently: I can't rembember how many (oneway='yes' or oneway='true' or oneway='1') there are in the mapnik style's sheets I use.

[OSM-talk] oneway yes or true

Re: [OSM-talk] oneway yes or true
True/false and Yes/No both give the same meaning to oneway, so there's only debate if the value should be leaning towards human- or machine readability. Personally I would lean towards human, shame on any programmer who's software cannot parse yes/no values. What would really add additional information to oneway is: 0, 1 and -1.

In both cases I am allowed to drive it like a oneway=true and it is the safest thing to do Safety is not engaged in considering a default to yes, but that's what you could do on any roads without a oneway. Leading to an unusable, but secure software. It's not like you can switch your eyes and brain off just because you have a navigation system. True again, this is a driver's requirement.

Imho only 0, 1 and -1 are the true options for the oneway tag. Actually, it would convey less information. Technically you are right, but by choosing an non-intuitive encoding that only people with some technical background and metainformation will understand, you are transporting less information by drastically decreasing the number of recipients - and people willing to deal with it. It seems to me that this is just the most basic example of a problematic tendency. Some people enjoy setting up very complicated structures because of the many things that can be expressed with them. But you need a lot of technical background to understand them and avoid their pitfalls and probably some advanced tooling to use them. On the other hand, the way I understood it OSM was a global initative and is happy for every additional mapper. If this is the goal, we need structures that you can understand and properly use without a degree in computer science. So back to the original topic: yes is definitely the most intuitive value and thus the most useful. My personal preference would be true ( but then I have a degree in computer science. :-) but I understand that it is less intuitive. But 0, 1, -1 needs an additional mapping table and is incomprehensible to most people, so I deem it unsuitable. bye Nop ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

We don't have enough developers on the OSM core site, but that's immaterial in this context. The ecosystem, however, is thriving. There isn't a day when I don't see some new program released that uses OSM data. Yet we still don't have _enough_ mappers. I'm writing this from an only partly-mapped town. Vast swathes of Britain are still Here Be Dragons and we're the second most mapped country (by volunteers) in OSM. cheers Richard -- View this message in context: http://www.nabble.com/oneway-yes-or-true-tp22242216p22247514.html Sent from the OpenStreetMap - General mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Yes Richard, but some things are best done in the editors. It's much easier for editors to highlight obvious mistakes, than it is for every single tool out there to support every possible spelling. Oh, sure, I wouldn't argue with that. Writing better editors is part of optimising for ease of mapping. But Potlatch autocompletes oneway only to yes/no, and from this thread it seems that JOSM is similar, so in this instance the editors are getting it right (hey, Potlatch got something right, break out the champagne). Slightly controversial suggestion: the quickest way to solve this would be to take or [oneway]='true' out of the Mapnik style file. ;) cheers Richard -- View this message in context: http://www.nabble.com/oneway-yes-or-true-tp22242216p22247591.html Sent from the OpenStreetMap - General mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] oneway yes or true
OSM2Go now automagically flips oneway tags, tags on ways like foo:left and foo:right, and forward and backward members in relations when the user reverses a way. Better explain what we do for oneway somewhere, this might as well be it. We inherit JOSM's presets system, so we use whatever UI-wise we don't get in your face about reversing stuff like JOSM does with the option set. Can't afford to on a tiny screen on a small device with a tendency to be slipped into a pocket and forgotten about. Simpler=better for us.

Possibly it should flash a little ambient warning about it briefly. If somebody wants to enhance oneway, please do directions in terms of the way's node ordering.

David Earl wrote: I can't help feeling the effort that I've noticed some contributors are putting into manually changing oneway=yes to oneway=true would be better spent doing something more useful. JOSM's preset puts it in as 'yes' (and that's what nearly everyone was doing when I started). Who's to say what the right answer is when there is no right answer.

David ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk David, Clearly you have run out of mapping to find time to spot this :-D I recall the very early discussions and the first draft of Map Features that we said it really didn't matter too hoots whether it was yes/true/1 as there was enough understanding in the value to know what it meant. I'm still tagging most stuff with true and I can't give a reason why. I'm not even remotely coding orientated so why I should have picked true/false over yes/no I cannot say. But like you, the time making the change is wasted. Far more productive to go and map something. Cheers Andy ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
