I'm trying to figure out how to write and read structured data to a

Data, but I'm feeling totally at lost after having been reading up
on Core Data for a couple of days by now.
That's what Core Data is for, yes.
This is what I would like to do:
1) I want to store several top-level objects.
2) A top-level object have a few optional attributes.
3) Each top-level object have two-way relationships to sub-objects.
4) Sub-objects has also a few optional attributes.
5) A top-level object may contain many sub-objects.
Obviously I would like to read and write to the data file as well
as create and delete objects within. There must be a simple way to
do this but I just can't figure out how...
Out of curiosity, what do you find not simple about doing the above
using Core Data?
It is easy enough to create the data model using xcode, but how that
connects to actual code is harder to see.
Maybe I'm just overwhelmed... I've had to learn about Sync Services,
Cocoa, xcode, the Foundation framework and not to forget Objective-C,
from scratch in just the last month or so. I'm new to the entire Mac
development environment (I'm coming from linux) so you can imagine
that my head is rather busy digesting it all. Anyway, I must say that
I find it the best thought-out development environment that I've ever
had the pleasure to work within.
Best regards,
