[Buildingdata] Portals

[Christopher Gutteridge]

A while back I was working on a vocabulary to describe entrances, exists 
and doors, what they gave access/egress from and what they were the best 
entrance/exit to use for a given spatial thing: 
http://neologism.ecs.soton.ac.uk/portals

It seems a bit complicated but most of it is just a repeating pattern 
for rooms,floors, buildings,sites. Basically, any "portal" can cause you 
to enter/exit/change what room,floor,building,site you are in.

A lift or stairwell can be modelled as a portal that allows you to 
change between the floors of a building. The front door for a house 
gives access to (and egress from) all of: the house, the ground floor, 
the hallway.

The "part of day" bit is a little sketchy but it's to allow statements 
about daytime, evening, night, which at Southampton is the most specific 
we can get access rules for most buildings. I'm not 100% convinced about 
the use subpredicates for types of security and accessibility.

While this is kinda exhaustive, for now we only currently plan to use it 
for recommending the best entrances to use for various lecture theatres 
(some of our buildings have multiple entrances on multiple levels so we 
hope this will help student satisfaction in some small way.)
