The concept of location must be present in any business ontology.  Two main types of location, physical and logical, are differentiated here.  They are so different that it may not be intuitive to think about them as part of the same category.  However, they do exhibit very similar semantic patterns, so it is interesting to show the commonality.

Physical locations have to do with space.  Space defined in three, two, one, or zero dimensions corresponds respectively to volumes, surfaces, lines, and points.  Points can be of two types: coordinate (x,y; latitude, longitude) or referential (on the fourth floor of the building; next to the car).  Logical locations include accounts, postal addresses, and network addresses (phone numbers; LAN ids, etc.).

We often say that the manager role manages locations; usually it is something at the location that is actually managed.  Locations locate resources and results.  Many locations can be spanned by the complex things we call systems.  They are both the source and destination of flows.  Any number of locations may be involved in a business situation.
