My ideas: 1. Implement validation methods that return NO (unless the new value is equal to the current one). 2. Throw an exception in setter methods if the revision is read-only. 3. "Accept" setter messages, but simply ignore them (keep the attributes unchanged).

Which is the best way to enforce read-only attributes? I'm leaning toward using both 1 and 2 above.


How about:

4. Make the UI elements uneditable to prevent changing the entry.

If you're concerned about programmatic changes I'd go with 1. and/or 2., also.
