A few comments on the ones that may not be obvious:

Build/version are used by some editors to expand on created_by

transport=car and transport=foot are the two common values for that key

bot=yes created_by values indicate overwhelmingly specialized programs (e.g.
the redaction bot)

The current best practice tagging for an import changeset appears to be
import=yes, source=* and website=link to the appropriate wiki website.

It is also useful sometimes to have internal upload details in the changeset
tags (e.g. a filename or unique ID which allows you to find which upload
failed if problems are later found)
