No, both name=* and name:*=* are needed even if identical. Name:* is not redundant because name=* does not indicate what language the name is written in.

That said, I surely know that many roads in Finland are lacking the duplicate name:fi=* tags but they should be added throughout the country (so no need to point out for those as "counterexamples").

Seems that my wording is not obvious enough in the previous message. The ditch does not have water (except perhaps after very heavy rain for a while in the lower end of it) in it so it's more like a trench than ditch for real. Many ditches, though, are empty much of the year anyway so it is hardly a significant detail for its classification.

It's "fake" in a sense that it looks like a ditch but only for the outdoor museum display purposes. "Vesisaha" next to it represents a historic saw that was driven by watermill. The artificial ditch does not actually transfer water anywhere but is making the watermill display to look more authentic. Also (FYI), all/most of these outdoor museum buildings have been brought here from elsewhere which explains why they just made an artificial ditch there rather than having a decommisioned watermill there (with real running water).

Ehkä tuolle b.j. tien talolle voisi lisäksi jonkun summittaisen start_date=2011..2012 laittaa, kun kerran tuo raksaobjektinkin antaa siihen vihiä koska on rakennettu, niin ei ole suoraan sanottuna täysin kopioitua tietoa helsingin ilmakuvista vaan ihan muuta kautta varmennettua faktaakin on mukana :-).

Juu. Ei muuta kuin raksa vaan tuosta b. j. tieltä pois kun on valmis. Sen hopeasalmentien raksan voi toki lisätä (taisitkin jo lisätä). Tosin tahtoo olla että noita omakotitalojen raksoja ei oikein tule kauhean hyvin päiviteltyä, kuten huomaat. Niiden olemassaoloa on vaikea muistaa enää siinä vaiheessa, kun talo on valmis eikä ole hetkeen mennyt ohi.

Joskus aioin käydä läpi kaikki >2v vanhat raksat mutta aikeeksi jäi. Kaikki lienevät päättyneet ja taloja saattaisi pitää päivitellä, osa voi olla jopa niin vanhoja että löytyvät jo uudet talot viimeisimmistä ilmakuvistakin.

Jostain syystä mulla ei nyt kartta.hel.fi:hin saanut mitään layereitä lisättyä, niin en voinut tarkistaa... Mutta onko tuo nykyinen talo sama talo kuin aiemmin? Tuossa kohtaahan on was:building=yes osmissakin mutta toki voi olla, että olen vaan kuvitellut, että uusi talo siihen tehty. Jotain harkkotiiliä ainakin muistan olleen pihalla vuonna yks ja kaks.

Raksa sinänsä jo varmasti valmis vuosia sitten vaikken olekaan tuosta mennyt ohi vuosiin, sama juttu muidenkin vuosikausia mun jäljiltä jääneiden raksojen kanssa, kun en ole niitä muistanut poistaa/katsoa ohi ajellessa myöhemmin.

Joskus saatat törmätä myös tähän addr-polyyn:

osm.org/relation/422628#map=12/60.21512031555176/24.994583129882812

Jolla on merkitty suurinpiirtein se alue jolta "kaikki" osoitteet on
kerätty.

Se on alv:n kartoituksen trackkäyspolygoni. Katsonut tuolta alueelta kaikki man_hole=heat (kaukolämpökaivonkannet) ja maakaasukaivojen merkit.

Voit koittaa zoomata oikein lähelle jolloin monet nodet saa kyllä
halutulle paikalle tai sitten toinen vaihtoehto on tehdä node kauemmas
seinään, siirtää se sitten lähemmäksi ja suoristaa sitten seinän nodet
viivaksi (ainakin josmissa mahdollista, varmaan iD:ssäkin mutten ole
sitä koskaan käyttänyt).

Feel free to, although I wouldn't expect some to give up on highway=mini_roundabout very easily (or even after some pushing ;-)).

You might be able to get 2nd tag approved though and just specify that it's 2nd_explicit_tag=yes by default for the highway=mini_roundabout which would already help this case somewhat.

Indeed.
If there's something in the wiki that doesn't make sense or is too restrictive, it either means that nobody thought about it, no body wrote their useful thoughts to wiki, or that some (rather few really) opposed sensible idea so persistently that the proposer just gave up (unfortunately the last one is far too common too).
"Mini" isn't particularly explicit on the meaning either like such 2nd tag would be.
I suspect this whole mini thing might be very contextual to some places (perhaps they're even called mini roundabouts in the natural language there) where the roundabout is just a small painting or something (here in Finland paint is not very useful during winter :-)).

The sign I'm talking about is this one:

osm.org/node/2065702927

True, however, most of the vehicles in here are smaller than those large ones. Even the leading part of the heavy trucks would likely follow the roundabout circle that has larger diameter than usual residential roundabout anyway. The middle shortcut through the very center is needed only for special permit vehicles that are larger than normally allowed dimensions, I think (I was lucky enough to seen some catamaran and trimaran special transports to use this route once and they had to also remove traffic sign from the middle too in-order to make the turn from South to East successfully).

For the small vehicles it's much more useful to indicate it as a real roundabout and they certainly don't want to cross the center due to the surface material.
I think that there's no good enough reasons to justify the wiki guidance given that the roundabout+mini area approach I used here should convey enough information to handle both cases (and one could even autogenerate reasonably good single point approximation out of this by connecting the ways to the calculated centerpoint).

I checked it from the wiki and it seems that the current definition is still the same. In addition, I think that highway=mini_roundabout wikipage should not ban this tag for areas like it currently does as there's clear use case for drawing the real circle using ways for smaller vehicles while also mapping it as mini (even the default rendering seems to support this for areas :-), IIRC it didn't back when I added that area).

Given that one can ride over the whole center area of that particular roundabout, it qualifies as "mini"_roundabout according to the definition that was given for the minis while I did that change (I don't know what's the current definition as they unfortunately occassionally change stuff behind mappers/tagging@ list back).

The obvious reason for all this is the needs of the nearby harbour. I think it's just a very rare exception and correct as is (I also understand why it looks strange to you :-)). And thanks for asking first(!) rather than correcting without better information.

Kuis sä nyt poistit sen kylän sit? Se on eri asia kuin suburbi.

I'll try to remember to take a photograph once we'll visit one of such playgrounds but I cannot give any ETA for that to occur since we anyway pretty randomly pick the playgrounds where to stop (like happened for that particular school yard too).

...And BTW, thanks for asking first when you didn't know how to fix rather than trying to come up something bogus yourself. I think it's the proper approach in case of any doubt about how to fix and results in better quality of data in the end :-).

It's a stick where you have a small standing platform. Up to two persons can somehow fit but mainly for single person use. The platform is 20-30cm above ground, approx 40cm diameter or so and you will be standing very close to the center of rotation if not even top of it if you're tall enough. By it's shape, a closest real world device it resembles is a spinner ("hyrrä" in Finnish) albeit it's anchored to that particular spot.
I'd prefer to not tag it as =roundabout as it's so different from an ordinary roundabout.

Unfortunately I couldn't find a image of one but you can imagine a pole to the center of this one:

In many playgrounds around here these non-rotating and the spinner ones are even next to each other.

Ok, thanks.

Sure, but's it up to you "fixers" to do what you propose, not me (I actually was kind enough to even comb the history feed to locate this data destroying change for you so that the data does not get lost). Please either do as you proposed or revert.
Thank you!
