Rumour has it that the grand father was a filesystem found in OS/2, so we are talking at least ten years of development i.e. I would guess the code correlation is now very low to zero. But the high level aims, idea and concepts, vocabalary or principles might still be similar.
As a user of the AIX file system, you have no need to understand the internals as all filesystem present the same user view and programmer API for access to files, directories, filesystem information and inode like information.
These interfaces are largely the same for Linux and AIX.
What exactly do you mean by "parse the Filesystem"?
What is the real question here?
I don't know of a paper discussing this further and I assume you can use Google to look up JFS2 as well as anyone else.
