Best way for diff. group of people/term-id/role to update, make new, delete and so also called CRUD

I'm sure a LOT of you are using such on several of your sites so sure someone would know and hopefully help, please?

On this site http://www.tinemuller.dk/test_drupal/ in the top click browse/CRUD - everybody can click a toilet and see all about it but only people with roles and term-id for each city can change the info but there are 98 cities so NO good to be in the top - How is the CLEVER way to do such things, please?

user_force_term module used
Vocabulary Name: Kommuner Type: Copenhagen

Terms:
Københavns kommune
Odense kommune
Roskilde kommune

They have the SAME role called "Kommune editor" but diff. terms - hope you understand what I'm trying to explain or please just ask for further info?
