note also the typo in the key "operator:decription". (where the simple key "operator" could be more useful)

Hello. the key "Public building" does not exists in OSM. mybe there is "amenity=townhall". please see the wiki
amenity=townhall

hello, the key "uocname" seems to be a typo. Is it?

The key "dateopen" does not exists in OSM.
See instead start_date=*

but is "reflorestação" the real name of the objects?

osm.wiki/Names#Name_is_the_name_only

Yes of course, sorry I will use more useful comments. tempted from the speed of level0 editor, sometimes it goes too far.
(In this changeset also the source is entirely a mistake!)
I don't know about the data accuracy.
I somewhat suppose that a clear typo (like a "maxsped=50") in the case when is NOT true (maybe is 70) is more serchable and identifiable as an error / spam if I fix the typo. Otherwise it lies in the deep of the database.
But Yes I will reduce the use of taginfo and similar tool. Bye, Daniele

Hi. If you remove the tag "tourism=hotel" there is no way to understand if the object is a hotel/ a museum/ a stadium/ etc

You mapped an object that has only a name tag. You need some tag to specify what kind of object is.
otherwise it will be impossible to know if is a office, a museum, or a ship wreck. :-)
I suppose is a:
osm.wiki/DE%3ATag%3Aoffice%3Darchitect

Hello,
the keys "Telefon" and "Webseite"
don't exist in OSM,
we use:
osm.wiki/DE:Key:phone
and osm.wiki/DE:Key:website

Hello. It seems there is a wrong key-value in this changeset.
"Tom=Björklund" ?

Hello. The key "entierro" has no meaning in openstreetmap.

"admi=6"

Hi, there is a typo on the key "admin", I suppose

what's the meaning of the tags "acessibilidade = yes"
and
"acesso = cadeirantes"
?

Mi sbaglierò io, ma non trovo tracce di questa direttiva OSM. Mi pare che in ML e sul wiki si sia stabilito diversamente. Non sono aggiornato?

"Le aree di circolazione che riportano date composte solo da giorni e mese, si inseriscono esplicitando il giorno in lettere. Es: Via venticinque aprile. Eventualmente usate il tag alt_name=* per inserire il giorno con i numeri romani. Es: Via XXV aprile."

If I understand, the situation is now correct.

ti chiedo scusa per averti indotto in errore: la mia nota "GSM" era un mio memorandum (dimenticato) che denotava una antenna (il mast con cella telefonia mobile) e non riguardava il nome dell'area industriale. Ho corretto

Ciao, la farmacia non va mappata con amenity=hospital (che intuitivamente è l'ospedale), ma con amenity=pharmacy
amenity=pharmacy

Hi, of course is hard to say, from aerial imagery. I used track in that case as a course first mapping, maybe waiting for local mappers to fine-tune the details (a road is better than nothing). And you are right that highway=residential should be more appropriate.
