An OMFI will carry the clip name. If that differs from the file name then yes, you lose the connection. But an OMFI embeds the audio so it will not link to the original media. Why specifically do you want this?
Automatic Duck does a more sophisticated export of a FCP timeline and may contain that metadata when transferring to Pro Tools. Fairlight now imports FCP XML files directly and they link automatically to the original files, providing the media is network shared. Fairlights run on a WinXP platform so sharing Mac connected drives is a bit complicated.
If you run MacDrive on the Win XP machine you should be able to connect an external Mac formatted drive with the original files on it.
I am working on a file based drama project. I am given a sound mix to edit with. The people dubbing the project have access to all the original audio files / separate tracks. To link the tracks to the original audio files, they need the metadata.
