Object Normalization

In the same line as Database Normalization - is there an approach to object normalization, not design pattern, but the same mathematical like approach to normalizing object creation. For example: first normal form: no repeating fields.... here's some links to DB Normalization:

Would this make object creation and self-documentation better?

Here's a link to a book about class normalization (guess we're really talking about classes) http://www.agiledata.org/essays/classNormalization.html
