Potential new validation rules?: information=* => board_type=*

[sun-geo]

It seems between 2009 and 2010 the tagging scheme changed a bit from information=nature to information=board + board_type=nature.

I found this by looking to this chart: https://taginfo.openstreetmap.org/tags/information=nature#chronology
And checking an old wiki version of the corresponding template from that time (third last table-line) gives a quite good evidence.

Would that justified for deprecating this tag & and add a new validation rule?

Seems there are also other combinations with , history and wild_life / wildlife, compare same old wiki version and taginfo information values.

Edit:

Similar for hikingmap & citymap, but this changed from
information=hikingmap to information=map + hiking=yes + map_type=topo
information=citymap to information=map + map_size=city + map_type=street

So, also osm-carto would show more specific icons on the map after these tag upgrades :-)

The two map examples are even documented as "possible mistagging" on the wiki: https://wiki.openstreetmap.org/wiki/Tag:information%3Dmap#Possible_Mistagging

I think adding these to the list of upgradable tags would be certainly beneficial. 👍

If you upgrade

information=hikingmap to information=map + hiking=yes + map_type=topo

then hiking=yes should also be visible and editable in the presets for information=map (preset).

The same for information=bicyclemap -> bicycle=yes

And also analogously for guidepost (wiki):
guidepost=hiking -> hiking=yes
guidepost=bicycle -> bicycle=yes
etc.

The advantage is that a guidepost or map can have more than one of the *=yes tags at one time (avoiding a semicolon-separated list), see information=guidepost#Examples (wiki)

But there may be opposition to use hiking=yes, bicycle=yes, mtb=yes, horse=yes etc. this way; compare old closed issue openstreetmap/iD#3832
