I have mainly put #REDIRECT [[Key:key_name]] on tags I feel are explained in the key page, in that case it will find the same page no matter how it is set up. Though some keys such as source should be hardcoded to point directly to the key, no matter what value is put inside.

Must have been like walking into a freezer, returning to cold London from your Brazillian Christmas Holiday

Are you editing in Potlatch, than you should think of another editor. JOSM and merkaartor have the adventage that you can save the changefile to your computer (before you upload), and if it uploads with error, or if it doesn't register in the API for some strange external reasons, than you can try to upload it again a little later.

goldfndr: That entirely depends on the value of the keys, IMO all common values should have a page, if not other at least a redirect to a common description of several values. Many keys can describe the common values, such as key:wood kan describe tag:wood=mixed, tag:wood=deciduous and tag:wood=coniferous, but each of the tags should redirect to where you can find the descriptions. JOSM already have a function to link to the wiki for help on the preset keys, maybe a future version loads the pages from a wiki cache? Maybe other editors also have or are getting similar features?

I saw the layer information, I think I can make a script to do a building import, and some other features, but the roads I need to separate into a sort of data-layer and trace by hand in JOSM, working on various solutions. Did you see my mail regarding the split.pl?

A plead for translation, and half is done within a few hours :D Maybe we can manage to get the number of stubs down as well?

HannesHH, I didn't ask for the german translation of the words, you obviously didn't read my post or didn't understand it. All the pages you are mentioning are in German, a language I do not understand. In order to be able to translate the above pages to Portuguese I need them in English or Norwegian, your call.

I support the idea of emergency_service= tags, that opens for the highway services that exists along some of the highways in Brazil, where a duty mechanic and a towtruck is present also. Could be good to have these on the map as that is places you can stop by if you have some mechanical trouble with your vehicle (not that they will not fix it if spare parts are needed, but can easily help you get dirt out of a fuel filter, tighten bolts, etc.)

Colin have a point as br is the language Breton, while BR is Brazil, but as we probably have no Breton embassies than this can probably be done either by make the test ignore case, bot to change all to uppercase, or let the test force all to uppercase. All of these will have same result.

Maybe merkaartor should be pushed more? I guess that one is somewhat more "newbie"-friendly than JOSM, though I do not like the entire Look-and-Feel of it. AFAIK all the tools for OSM supports i18n, whether it is in translating menues and help information or different font types. AFAIK it also supports r2l.

If you don't know these terms, i18n is internationalization (translation) and r2l is right-to-left fonts.

The right way to tag it would be railway=construction + construction=, but anyway, yet again OSM will be the first to show a new feature :D

JOSM is a Java based editor you can run on your own computer, or via the webstart applet (dunno the link), if JavaScript might solve your problem, than Java will for sure.
And for a side note, MapZen are not even in Beta mode yet, only an early alfa version, if you find the right place to mention your problem, than the developer team will see it and put it on their TODO. I toyed with it myself for a short hour, though did not save, and it smells of alfa-release, but I guess it looks promising. One thing I did not like was its merkaartor way of handling ways and nodes, I prefare JOSM above Potlatch above merkaartor on their way of handling ways and nodes.

Tags for reality, I didn't know Toucan crossing was a term for some type of signalled bicycle crossings, can't remember seeing anything like that in Norway while I lived there, and I definitely havn't seen any here in Brazil where I live now. For me there exists only two types of crossings to tag, pedestrian crossings, and signaled pedestrian crossings. Bicycles goes more as normal traffic than as pedestrians in Brazil. Nuff said Brazil have some weird laws regarding access for bicycles, that is valuable data for a bicycle routing engine.

snowshoe=designated (when wearing snowshoes you are obligatory to use this route even if alternatives exists)
snowshoes=yes (you are allowed to use this with snowshoes)
snowshoes=no (you are not allowed to use this with snowshoes)

The only sane usage I can see with this is together with ski-tracks, where I would understand usage of snowshoes might damage the prepared tracks, and therefor prohibited or regulated in some way. If it is a regular "snowshoe walking route" or "snowshoing event" than relation=route should be used.

Yes, roads can be under construction for years and years. Where I live the upgrade of the airport (that was started when the passenger capacity of the terminal was reached) is still underway 25 years or so later (the road exit to the new terminal is ready, but not a single wall is in place yet), the bypass highway ends halfway, another bypass highway goes zigzagging because there are still work going on on various parts of the road (8 years at least), one of the trans-national highways stopped 25 years ago because of funding, and now it cannot continue construction work due to protection issue such as suggested national parks. The road up to my inlaws was supposed to be paved long ago, money have been granted at least 5 times from the federal government, but there are still no paving on that road.

Not to mention the rest of Brazil. Should've tried to get some journal coverage, don't think there have been much OSM in Brazilian media yet.

As we have serious problems internally in Brazil, adding foreign cities is diverting the attention. I guess that a future project might be routing between south american capitals, but at the moment we need to get the 26 states of Brazil to route together.

Brazil is even worse, where you can have different post code on left and right hand side of the road, where a road might change post code when passing into another suburb, some buildings have its own post code etc.

If editing with one of the offline editors, such as JOSM, you can save your data in .osm.xml format and later run some renderer on it to render your own tiles if that is what you want.

in JOSM you can make a node where you want it to be merged, select the nodes and push 'm' for merge. You can also see your mouse pointer when howering over the way you want to attach to see when you will make a new node and attach it to the way, or just create a node at the side of the road. Other tools have other opertunitites. There's always more than one solution.
