took a break, got to think about some things

Took the day off and crashed. Work this week and next on COODBMS will be a bit irregular as we are moving to Raipur. And that's a very long train trip.

I've been thinking about levels of an application. At the level where browse operates, all rolons are just variations on a theme. So it is dumb and stupid and can operate on the structures of any application.

Taking access control as a sample application, clearly there are (at the application level) different kinds of rolons with constraints about where they can be found, relationships, etc. Now obviously we can build up some meta data for all this and use this at the UI level to both impose the constraints and assist the user in defining appropriate requests. I'm just wondering if there is more to it than that.
