The Rock Ridge Interchange Protocol (RRIP, IEEE P1282) is an extension to the ISO 9660 volume format which adds POSIX file system semantics. The standard takes its name from the fictional town in Mel Brooks' film Blazing Saddles.

The extension adds support for storing Unix-specific file information on ISO 9660 CD-ROMs. The availability of this information allows for better integration with a local Unix filesystem when a mount operation is performed (also see Mount point).

These extensions are, briefly:

Longer file names (up to 255 bytes)
Fewer restrictions on characters allowed in filenames
UNIX-style file modes, user ids and group ids
Symbolic links
Deeper directory hierarchy

Amiga Extensions on Rock Ridge

ISOAmiga Rock Ridge specific extensions support the additional Amiga-bits for files. There is support for attribute "P" that stands for "pure" bit (indicating re-entrant command) and attribute "S" for script bit (indicating batch file). This includes the protection flags plus an optional comment field. These extensions were introduced by Angela Schmidt with the help of Andrew Young, the primary author of the Rock Ridge Interchange Protocol and System Use Sharing Protocol. The Amiga extensions are recognized by Amiga program MasterISO, and should also be recognized by MakeCD and Frying Pan, but the support by latter two programs is uncredited. Amiga filesystems supporting the extensions are AmiCDFS, AsimCDFS and CacheCDFS. Users who want to access comments and protection bits of their Amiga files present on CDs could simply mount some new logical units associated to the same physical unit, but using Amiga CacheCDFS as filesystem.
