You're still missing the "Finder flags" (e.g. the locked bit, custom icon
bit, bundle bit), the type/creator codes, and any other HFS/HFS+ metadata
(which is not stored in the resource fork).
If you use the OS X APIs for "lossless" file copy, you get it all. Try
copying a "Mac file" from an HFS/HFS+ volume to a UFS volume in the Finder.
You'll see how it creates two files, "foo" and "._foo" on the destination
drive. "._foo" contains both the resource fork *and* all the associated
metadata. The Finder knows how to "reconstitute" the two files as well.
either when copying back or when reading the file on the UFS volume.

Well, if you could write an XS module that hooks into the same APIs that the
Finder is using... :)
