Aside from the existence of generator:source=wind this demonstrates he hasn't quite understood it yet. The new scheme should be added[1] to the stylesheet, but the old scheme should not be removed. At least not before the overwhelming majority of existing objects are compatible with the new tagging, or after some extensive time has passed to allow this tag change to propagate.

[OSM-talk] Wind turbines no longer rendered on mapnik layer
Hi, In changeset 10678735 [1] a new user has removed all power_source=wind tags on wind turbines. The result is that wind turbines are no longer rendered on the mapnik layer. It is true that the power_source tag is deprecated, but being deprecated does IMHO not mean that a tag should be removed in a massive clean-up operation, especially if you do not follow up on the consequences of such a change. Adding the new generation tag (generator:source = wind) is fine, but removing the old tag is not. I have emailed the user and asked him to revert the changeset. Cheers, Morten [1] http://www.openstreetmap.org/browse/changeset/10678735 ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I'm curious why the power_source tag is set to deprecated while the Mapnik stylesheet has not been adapted to include the new tag. I would think that would the logical step. No use in making a new tag that is not rendered, especially when the old tag is supposed to not be used anymore. The wiki is also less than helpful. The wiki page of power_source [1] is an immediate redirect to generator:source [2] with no mention that power_source might be deprecated.

2012/2/15 Maarten Deen md...@xs4all.nl I'm curious why the power_source tag is set to deprecated while the Mapnik stylesheet has not been adapted to include the new tag. I would think that would the logical step. Not rendering the new public transport proposal is slowing down the change to the new set of tags. Maybe this is the faster way to make a change in mapnik.

Re: [OSM-talk] Wind turbines no longer rendered on mapnik layer
I know the stylesheet maintainers are backed up, but is there a ticket indicating what additions to the stylesheet are desired in trac? The only mapnik ticket I can find relating to public transport is http://trac.openstreetmap.org/ticket/2798 Do any of the general purpose styles (e.g. mapquest, cloudmade) render anything for any public_transport=* values?

Do you already know the Transport layer on osm.org? There are also several other public transport maps, see http://wiki.openstreetmap.org/wiki/Public_transport#Maps I agree that public_transport=stop_position and maybe platforms should be rendered on mapnik as well. bye ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

There are no deprecated tags, and nobody has the power to set a tag to deprecated. What's even more problematic is if people try to automatically change a large number of objects away from what they consider deprecated to some new tagging scheme. This requires a much broader approval than a few votes cast on a wiki page that nobody reads; we expect any automated or even mechanical edit to be discussed on the mailing lists beforehand. No use in making a new tag that is not rendered This is not true; there are many tags that are not rendered and the map on www.openstreetmap.org is not the arbiter of what tags should be used. The wiki is also less than helpful. The wiki page of power_source [1] is an immediate redirect to generator:source [2] with no mention that power_source might be deprecated. Yes, this is not helpful, and certainly no basis for effecting an automated edit. When looking at the other edits of the user who did this edit, we can see that not only did they make this tag change across a number of changesets; they also imported wind turbine data from a third-party source. Unless they can point to a community discussion and agreement that preceded the import, they should not only revert their mass edit, but also remove the imported data because it doesn't meet our import guidelines. Morten, could you keep us posted about any replies you get from them. It would be preferable if the Netherlands community could deal with this but DWG will be happy to step in if there's a problem.

It is great if you fix bugs in the osm tags -- misspellings and such -- but you really should not remove tags that someone put there. If tag removal is to be carried out, it is best to discuss it on the mailing list first, but in general, you never know if tags are being used by someone, so it's better just to leave them. They do no harm. If you are thinking of wasted storage space, think of the extra data you produce by generating a changeset plus new versions of all the objects...

The fact that he didn't revert his changesets and attempted to re-add the deleted tags is not great. I think he has ended up adding power_source tags to objects that didn't have it before. How can we deter newbies from imports and mass edits? It seems he didn't know what he needed to know about prior discussion and agreement, he didn't know how to ask a wide enough audience, he didn't have the experience to know how to fix the mess he made, and he didn't understand the basics of OSM. This is not the first time. I can't blame people for not knowing, so how do we inform them, before they wade into problems? -- Cheers, Chris user: chillly ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
