[FLOW3-general] Two questions for many-to-many associations

[indira]

Hi everyone, 

I have a many-to-many association between two entities, but I need some 
extra attributes on that association. 
I found this link 
https://groups.google.com/forum/?fromgroups#!topic/doctrine-user/0dh8lgUudvc%5B1-25%5D where 
they recommend to have a third entity for the relation itself, and then add 
the extra attributes there. My first question is: if I do this which one is 
the owning and inverse side?

Also, I will need another table to track some information. On that table I 
will have three different entities related with some extra columns, so my 
second question is: can I just create a repository for this one without any 
model? What would be the best way to do it?

Thanks in advance,
Indira.
