- I'm not familiar with the ISO1001 format, but I would like to suggest a textual
- self-documenting format, like RFC822. You don't need to put the actual field
- names in every file header if you establish a property file at the beginning of
- the archive. For example:
-
- FieldCodeset: ASCII
- FieldSeparator: <0A>
-
- [ these two would be required for the initial header, and need to be in an
- agreed on language. ]
-
- HeaderLength: 96
- BodyLength: 0
- Common: HeaderLength,BodyLength,FileName,ModificationTime,Owner
-
- [ This establishes the common fields until the next Common field ]

- [ These are the header length, body length, filename, etcetera for the first
- file ]
-
- FileComment: Remember to edit this for local architecture[...]
-
- [ This is a part of the file system on the originating system. Would probably
- end up in usr/local/src/pax/.Unresolved/Makefile on UNIX ]
-
- #!/bin/make
- [...]
-
- This should require a minimal amount of additional space, and would be
- indefinitely extensible. Older versions of the archive program could
- discard unknown headers, or stick them in a file somewhere for later
- messing around with. It should also be relatively easy to treat as a fixed
- record length format.

- Inherent.

- > - Be extensible, to allow for future support of security information,
- > contiguous files, system management information, special files,
- > larger field sizes for dates, times, file lengths, etc.
-
- Inherent.

-
- With the caveat that a standard character set be used for the first two fields.

-
- Inherent.
-
- > - Encryption of individual files in the archive
-
- Simple extension: new file header.
-
- > - Compression of individual files in the archive
-
- Ditto.
-
- > - Translation of file contents between differing

-
- Ditto. ( add Body-Type )
-
- > - Storage of filesystem specific information (such as inodes)
-
- Ditto.
-
- > - Direct mailability of the archive file (without translation,

-
- Probably ditto, assuming no magic in the bodies or lines that are too long
- for mail.
-
- This is obviously not a complete proposal. I would appreciate feedback and
- suggestions, and if they seem positive I'll go ahead and write a real proposal
- up. The intellectual property status and usage of RFC822 is presumably not
- going to be a problem.
