[TYPO3-dev] MM relations with meta data

[Elmar Hinz]

Hello Steffen, Wolfgang and others who may know this,

as you seem to have some deeper insight into the complex TCE classes, maybe
you can answer this questionss:

To work on with CCF
(http://t3flyers.wordpress.com/2006/09/14/tep-common-category-framework-ccf/) 
I need a common mm table for different relations to the category tree. At
least one meta information field is needed for each mm entry. The task
of this field is to store a flag that keeps the different types of
relations apart.

a) Do the recent T3 versions provide the possibility to store such meta
informations together with mm relations? (TCE) If yes, how is this to do?

b) Is it possible to filter a flagged subselection from an mm table into
backend form select inputs? (TCA) If yes, how is this to do?

Regards

Elmar
