Organizations models companies, and makes them parties.
It is if you want a data model for companies or organizations.
The data model looks good. You can add in unlimited addresses and phone numbers, and it handles international formats. I think Jon thought through this pretty well.
But I also haven't used it very much yet.
So I don't think using categories would work in this case.
Bart said that he thought it was okay to write a UI for a service, so unless I hear otherwise, I plan to work on it today.
