I'd be inclined to start here:
I'd typically put the variable bits under /var,
/var/opt - for 3rd party applications variable content
/var/local - locally installed stuff not matching the above or
/var - elsewhere under var for OS/distribution packages
Configuration bits under /etc, e.g. likewise:
/etc/local, /etc, /etc/opt
Static bits would generally be under /usr, e.g.
or /opt for 3rd party stuff.
/usr /var /etc /opt - with /opt functioning similar to /usr, but for 3rd
party stuff, then, if applicable, subdirectory of opt or local - except
no /opt/opt or /opt/local, then typically package name (or for 3rd party,
often vendor_name/package_name) when under /opt or /var or /usr/local,
but many things may go, or also go more directly into suitable
directories, e.g. /usr/local/bin/name_of_app_executable. These can be
versioned with symbolic links to preferred/default version.
Anyway, that's where I'd generally put things physically. Symbolic
links can also be used to aid in logical
Standards/conventions will vary depending upon environment, e.g. the
above would mostly apply to POSIX/SUS/Unix/Linux/BSD, but not as much so
for Microsoft, VM, MVS, etc.
"Of course" it all should be reasonably configurable (e.g. with suitable
build/install options), and packaged appropriately (distribution/flavor
packaging and/or CPAN). Things may also change, e.g. from "local" to
not in a given distribution if that something becomes package provided
by that distribution.
