Hi  j o a r

Thank you, that answers my question precisely, even though the answer is "don't do that". It matches whet I have done.
- Do modify dataRepresentationOfType and loadDataRepresentation:ofType:
- Don't mess with NSKeyedArchiver and coder. They have their own agenda with handling an object graph. Even if I could write csv versions of the class instances NSKeyedArchiver would want to include the information that they were in an array so it would add information to the output file.


Thanks for your help

Denis

That's not the part that worries me. My question whether I should be writing this CSV conversion stuff inside the standard methods encodeWithCoder and initWithCoder, and if so how. It seems the Cocoa architecture has a well-thoughtout mechanism for archiving and I should try and work within it. My problem is the example I have produces a binary coded disk file and I need csv text. I want to make the Cocoa archive mechanism work with csv.

Why not do it in the dataRepresentationOfType: and loadDataRepresentation:ofType: methods of your document subclass? NSKeyedArchiver provides a way to store / restore an object graph, and it provides it's own storage format. Since neither of that seems to be something that's really useful for you, I'd suggest that you avoid using it for this particular purpose.
