This is the best documentation I have come across, although it looks like it is literally operated by one guy, BJ. There are some really awesome visual layouts of the someone convoluted Odoo model data structure. I had to use the api to query all the models, & including all their relationships there are ~498 data points.

The search function actually works quite well for looking for certain models or relationships. Odoo itself should really invest the time to bulking out their documentation. One thing I would love to see in their V8 API docs is some usage examples when referencing their methods.

P.S. - can someone please link me to a straightforward explanation of how Users are structured in Odoo?! res.partner ? customers ? they have even come up the 'locations' dropdown when I create events.

Thank you, that explains how it works... What wasn't clear were the options to enable it which I found.
