Designing a FOSS PDM for FreeCAD

[grd]

That is completely true, see https://github.com/grd/FreePDM but actually what I am writing right now is a VCS (Version Control System) in Go. And I also posted it in "golang-nuts", see https://groups.google.com/g/golang-nuts/c/l1t_mr6nP14

So the problem that I am facing is that the VFS has multple layers and I think that each layer requires a different VFS and to be honest I am a bit puzzled ;-) because I just don't know where to start and if this is even possible. I think so but how?

Edit: Okay, i am gonna say a bit more because I think that you are probably as puzzled as I am.

Level 5 is the file level. In there, there are a bunch of files. Some are RW, others RO.
Level 4 is the version level. It shows the number of levels (and maybe also a "new level" button.
Level 3 is the "normal file directory" level. In there it should be possible move / rename / add and rename actions are possible.
Level 2 is the "ordinary folder". The user should be able to add / rename / delete folders.
Level 1 is the "primary folder". Only admins are allowed to put some directory here.

So I think that this requires multiple levels of VFS. Am I correct?
