SELinux uses both. Things like "I put a file in my public_html directory"
are a good example.

Its object based in the sense that the origin of the data might matter
(eg 'no app which opens the credit card db creates a file httpd can send')

Its path based in the sense that public_html has a path based meaning by
convention understood by httpd. Copy a jpeg into your public_html and it
will be labelled up for http access under the Fedora shipped rule sets.
