VMS' file system has versioning. You'd get a file name like "login.com;1" for the first version, and so forth.
Not sure about metadata. ISTR that "files" could be more than just your usual flat file or executable -- variable and fixed length records were intrinsic file types. There was also a lot of information stored in the metadata, whether or not it is extensible is a mystery to me.
If you do find a linux file system that supports versioning I'd like to hear about it, since I'd find it handy in some cases.

Hello List.
Does anyone know of a file system that supports dynamic meta-data and file versioning?
By meta-data, I mean information about the file. Typically this would be things like created/modified date, etc. but I would like to be able to store other meta-data, perhaps things like "customer id" etc.
By versioning, I mean, when a file is modified or deleted the previous version is automatically saved.
I would like this to be a file system available under Linux but I am curious to hear of any file systems that are like this.
