I'm implementing a system which has structure like in my question: Design question: what's the role of WFS-T in this kind of webapp?
There's spatial data which is updated through WFS-T and non-spatial data which is updated through traditional (Java) web application.
When user updates non-spatial data, it is easy to implement authorization rules such as
if current_user = sales_region.manager AND sales_region.status = ACTIVE then all spatial fields can be updated
But can I do the same for the WFS-T geometry updates?
if current_user = sales_region.manager AND sales_region.status = ACTIVE then sales_region.area geometry can be updated through WFS-T requests
Isn't the WFS-T interface just an open XML interface? Anyone who has http access to it can modify, add and remove geometries at will? How could I add business rules checks to protect the geometry updates?
I know I could protect the whole WFS-T interface so that only some users can access it altogether, but that's not what I am after. I need to allow or deny some updates based on the data and some defined business rules.
Are there any easy solutions for this?
