Redaction_id will have bearing on the redaction bot
https://wiki.openstreetmap.org/wiki/OSMF_Redaction_Bot
Background: when OSM changed to ODbl, all changes made by people who did
not agree had to be redacted.
visible in the changeset will be the same as for node/way/relation: you
can delete an item, and when it is deleted, visible=0.

Dear all,
After the discussion that I started about the database schema I tried
to create a wiki page that explains it, I started the page on my user
wiki-page [1]. I started with few tables, but some elements present in
the tables are not so clear to me.
So If you wanna try to contribute to that page, since a description of
the database can be provided to everyone. I will continue to modify it
,trying to understand all the tables.
Thanks to everyone that will help, or just make a suggestion about it.
Best,
Lorenzo

Is it still true that in the OSM database, areas are not
represented as such?
areas can be represented as areas through multipolygon relations
which are always areas or by help of an additional tag
(area=yes/no), or through plausibility (tags and their combinations
may imply an area or not). There isn’t a dedicated area object,
maybe this is what you meant. Areas are represented with ways, and
tags or relations are required to define the ways as areas.
That would mean, for instance, that a pedestrian zone, let’s say
a big square in a city, cannot be made to be crossed diagonally
when used in a route planner. Am I right?
typically routing engines operate on graphs, i.e. they do not route
diagonally across areas, but this isn’t related to the question
whether there is a dedicated datatype for areas or not.
