paraphrasing

[GUEST2008]

Hello

I'm not sure I understand the sentence below:

Beyond the kinship convention, no other law enforcement is required in Aboriginal society ...

--- "kinship convention"? Can someone try and paraphrase it for me, just to make it clearer?

[The French]

Hi, I am a learner,

but I think the meaning is something like a convention where the focus is the parent's relations.

Hope it's help you.
