[TYPO3-mvc] relations with metadata

[Pascal Jungblut]

Hi Franz,

>> I'm currently working on tx_community for the Google Summer of Code and, starting with profiles, I have a question about relations. In particular it's about the friendship (yes, that's the common term in social networks) between users.
>> When one user wants to add another user as a friend, the other one gets notified and has to confirm the friendship. My question is how to technically implement those relations. Ingo and I have had several ideas:

thank you very much. You're absolutely right: as the friendship does have additional information, it must be an own object. I will implement it as a "friendship" object as you suggested. Again, thanks a lot.
