[Solved] What is a canonical file path?

The journalctl man page speaks of "the canonicalized binary path". So I asked myself, what this is. The gnu-documentation of the command realpath states:

"realpath expands all symbolic links and resolves references to ‘/./’, ‘/../’ and extra ‘/’ characters. By default, all but the last component of the specified files must exist",

which is supposed to be a canonicalized file path form.

Is this the general definition? Are there other definitions?

Basically, whatever the output of realpath is, that is the canonical form.
That is, resolving /./, /../, symlinks and removing extra /
