This appears to be a text property list, almost. You don't include the outer
brace pair. How do you read this "string," and how are you applying it to a
managed object?

What "takes" it? The managed object?

What is "value?" How is it obtained? Have you examined it in the debugger (or
through an NSLog()) to verify it isn't nil?

Nothing in Cocoa interprets plist data unless you explicitly put it through a
serializer, such as the array- or dictionary-with-contents-of-file initializers
or the NSPropertyListSerialization class.
But you apparently want Measure/Property to be interpreted as dictionary
key/value pairs (net of the absence of enclosing braces), but you don't want to
interpret the dictionary assigned to Property. The deserializers don't work
that way; they convert the nested structures to arrays and dictionaries all the
way down.
You'll have to show us your actual code. What's happening depends on what
you're actually doing, and a narrative description of what you meant to do
doesn't tell us enough to know what you did.
And please don't tack question marks onto the ends of declarative sentences.
