We'll have to dispel some misconceptions. Subversion's data model is
significantly different from CVS's. Tags (and branches) are not
properties of files, they're just (sub)trees within the repository.
Creating a tag or a branch is exactly the same as copying a directory:
the only thing that happens at the repository level is that a new
version of the directory is created.

The /path/ of the file implies which branch or tag it belongs to. There
is no other information you need.

You should also see the name of the tag in the path of the file.

See above; you'll see which path was created.

The structure of the repository is entirely free-form. The
trunk/branches/tags convention is exactly that: a convention, nothing
more. Of course it helps to pick a convention and stick with it.

I'd very strongly recommend to use one of the existing Subversion mailer
scripts. There's one in the Subversion repository:

https://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/mailer

but there are others. You can certainly use this script to see how it
gathers commit info from the repository.
