crossing=zebra

[Don-vip]

Since today the Taginfo integration test raises a warning for ​osmwiki:Tag:crossing=zebra.

It is used more than 500.000 times and we don't include it in default presets, I don't understand why we didn't get the warning before?

We support crossing_ref=zebra though.

Because tags without wiki page are skipped in the test. ​​osmwiki:Tag:crossing=zebra was created yesterday.

[Don-vip]

Wow, we had an undocumented tag used 500.000 times? Are there others like this?

Yes, see ​https://taginfo.openstreetmap.org/tags and sort the table by the wiki column. (edit: 1580 tags if I counted correctly)
However no wiki page doesn't mean undocumented. The tag can be documented on another page (e.g. ​osmwiki:Key:crossing in this case)

[Klumbumbus]

We could test how much tags we get if we remove the no wiki page rule in our test. Maybe this rule is obsolete meanwhile.

Lots of these tags without wiki page we already have in our preset (cuisine, capacity, colour, denomination,... ) or can be ignored (source, attribution, operator, start_date,...)

@Klumbumbus: what do you think we should do with crossing=zebra?

[Klumbumbus]

I think we should support it. It makes more sense than crossing_ref=zebra. I'll do the change.

[Klumbumbus]

In 14362/josm:

fix #16793 - add crossing=zebra

[Klumbumbus]

In 14363/josm:

see #16793 - fix indentation; add icon for craft=electritian (eco-systemedic-energy-A-2.svg from openclipart.org, modified, CC0 and PD licensed)

I have a big issue with crossing=zebra.
il prevent to fill in the other value for crossing like crossing=traffic_signals crossing=uncontrolled
the wiki ​https://wiki.openstreetmap.org/wiki/Tag:highway%3Dcrossing said
that crossing=zebra is a shortchut for crossing=uncontrolled + crossing_ref=zebra in the UK
but a lot of zebra also in UK and outside UK have traffic_signals
so at the end, crossing=zebra has no meaning... maybe the previous contributor mean crossing=uncontrolled + crossing_ref=zebra
but maybe he mean only crossing_ref=zebra

a few mapper working on accessibility are working on several contry scale automated edit to fix it.
so maybe it's better to avoid using the multi-meaning crossing=zebra
I'll open a thread on tagging.

(sorry for the anonymous post)

[Don-vip]

I plan to release 18.10 tomorrow. Maybe we should revert this change for now and revisit the issue next month?

[Klumbumbus]

In 14370/josm:

see #16793 - revert r14362 for now

[Klumbumbus]

In 14372/josm:

see #16793 - forgot to tranquilize Jenkins

No, crossing=zebra is the one that makes no sense.

I support comment 11.

What was the result or was there no result or no discussion ? Link?

I am in favor of wontfix and would even like a warning about crossing=zebra.

[skyper]

Can this be closed as "wontfix"?

[taylor.smock]

We now have crossing:markings which has zebra as an option, and we also have crossing_ref with zebra as an option, so I don't think crossing=zebra will really add anything.

With that said, I think someone (probably me, when I have time) should go through the ignoretags list and figure out if we still want to ignore them.

[dieterdreist]

I also support crossing=zebra, works for me. With respect to comment 11, any tags are tainted by people tagging without knowing about the specs. I also find lots of crossing=marked or crossing_ref=zebra for traffic signal controlled crossings. That's not a good argument because we could stop using any tag if some errors were to stop us from using them. As long as we have many different ways to tag the same thing, people will continue to be confused.
