Core-Data Non-Standard Attributes

Hello and Happy New Year!

I am developing a document based Cocoa application for my diploma thesis which uses CoreData to realize the data model.
The application deals with primitive float arrays. I would like to avoid using an NSArray with NSNumber objects since the element count can be very high.
My problem is to store the float arrays persistent with my data model.


Apple provides some documentation about storing non-standard attributes
[http://developer.apple.com/documentation/Cocoa/Conceptual/CoreData/ Articles/cdNSAttributes.html],
but they are only talking about "structures supported by key-value coding (NSPoint, NSSize, NSRect, or NSRange)" in the "Non-Object Attribute" section,
so i'm a little bit confused how to implement custom attributes for my float-array or other C-structs.
Can i do it the same way as described in the "Non-Object Attribute" section of that document?


Thanks and Greetings!

Volker
