Linux uses MIME types, see Internet media type

On my system (Slackware 13.0) there is a MIME database in /usr/share/mime

Update:

"GNU/Linux" systems with GNOME or KDE, use MIME types to determine the type of the file and from the system and user preferences choose the application used to open that file, if a mapping if defined for that particular type of file.
