Hi Ramiro,

http://docs.neuroinf.de/programming-plone/ate

and in particular

http://docs.neuroinf.de/programming-plone/ate#2-23

might give you some pointers.

Not sure I understand your question here:
In archetypes, fields have a property called 'primary' which
defaults to False and which tells the 'PrimaryFieldMarshaller'
which field's value to return on serialization requests
Having more than one field declared 'primary' doesn't make
much sense but won't break your system as the marshaller
just takes the first primary field it finds.

If you are asking: how do I provide two fields in a schema
that manage the same value? Look for what we call "field sharing".
Example

Schema((StringField('field1'),
         StringField('field2',
            accessor="getField1",
            edit_accessor="getRawField1",
            mutator="setField1",
          )
        ))

Now 'field1' and 'field2' are synchronized in terms of their
value but can be configured differently (e.g., be part of
different schemata sets, have different visibility, different
help messages, etc.)

No reason to excuse. There are a lot non-native English
speakers around here.
