Just curious. Which Core Data document format are you trying to reverse
engineer: XML, binary, SQLite, or all of them?

Using assertions in an importer is one of my more-effective reverse
engineering techniques.

FWIW, Omni's open-source data objects framework was our response to our

Using coredata with a documented format should probably be accomplished with an
NSIncrementalStore subclass rather than trying to reverse engineer the existing
undocumented format.

I think you'll find that the reason Apple doesn't publish some
specifications is specifically so they CAN change them w/o breaking

I do, and I do *very* well at it. But I certainly cannot estimate
reverse-engineering an undocumented format; it would be madness for anyone to

OK this is really creepy.
KickStarter has the reasonable requirement that one verify one's
identity. So I entered my first and last name, my real birthday -
which I never post online _anywhere_, so as to avoid identity theft,
and my present home address, which no one at all knows about because

I'll look into what Cocotron and GNUStep have done before actually
launching my KickStarter Project.
Just about their very first requirement is to state one's funding goal
and time deadline. I just took a wild guess and specified thirty
days, and twenty thousand dollars.

I believe that some of the work on this has been done already; Cocotron and
