Additionally there will be changes in how tags are propogated to ranger
in that whilst today you just associate a tag (classification) with an
entity, it's more useful often to associate the classification with a
business term, and then associate that with the entity.
The changes up from the core atlas, will go through a new API
(ATLAS-1696) and changes in ranger (RANGER-1454) - if approved (this is
still work in progress/unreviewed thus far), so feel free to engage in
the discussions there too.
In terms of in general inheriting the classification ... overrides will
IMO be needed (as David mentions) since sometimes a derived table will
require the same classification, for example around confidentiality,
whilst other times data could be combined and need a HIGHER
classification whilst in other cases data may be redacted, requiring a
LOWER classification ;-)
