Yes, please fix these corrupted tags. I marked them (12 nodes) by "fixme".
Thanks alot, Alexander

what means key "I=1" (unknown key, not used anywhere else on the plant).
Could you please fix this?

please follow the wiki-guidelines:
wikipedia=*#Examples
wikipedia="lang:Article Title Name" .
This helps processing/using the data. Thanks, Alex

please follow the wiki-guidelines:
wikipedia=*#Examples
wikipedia="lang:Article Title Name" .
This helps processing the data.

please follow the guidelines for wikipedia-key, see wikipedia=*#Examples
osm.wiki/Tag:==> no full link, only "fr:Title of Aricle"
This makes it easier to use (same style for all wikipedia-tags). Thanks

please use only valid tags, not "source="

please do not use empty keys, like way/442768353

bitte keine tags "4=node" wie bei node/4357962525 vergeben. vg Alex

danke für den hinweis.

please fix node with 2 meaning: guesthouse+hamlet should be 2 nodes

it had place=country, but you are right: it is not acceped by the others.

Open projects (like OSM) work best, if the majority of supporters agree on a common set of rules (or best practices). To write this down wiki.openstreetmap.org has been set up.
99.99% of wikipedia-tags follow it.
Today we have 770407 wiki-tags, and only some (<10) using full link.
If there is a full link, it decides to use http vs. https and m.wikipedia.org (mobile) vs. www.wikipedia.org (normal).
Of course you can do what you want, but the project would benefit most, if you copy-paste from the title (the bold text in browser) and not from its address-line.
Feel free to check the counts on taginfo:
https://taginfo.openstreetmap.org/keys/wikipedia#values

could we agree to do it according guidelines ?
There are 770k wikipedia=lang:OK;
plus 11k x wikipedia:en=OK;
Write extra exceptions into tools would be useless extra work.

please follow the guidelines for wikipedia-key (no full link). it makes it easier to use by tools.

I removed your 4=2 (key=value). I think it is a typo.

since days you change wikipedia links in Japan. Please follow the guidelines under:
wikipedia=*

wikipedia:en=en:Name is wrong.
Language (en: is either in key or value, never both).

https://taginfo.openstreetmap.org/keys/wikipedia%3Aen#values shows, you are tho only one on the planet creating these strange wikipedia strings.

Additionally: wikidata.org service was set up to translate between wikipedia languages, so you change is not really needed. Beside this: the number of people speaking english is higher than the number of users being able to read japanese wikipedia articles.

please always add the language to wikipedia, e.g. wikipedia="uk:Name"

wikipedia=*
