This section describes a few samples of Business Aspect Servers. They are the “stable” part of the IMA concept.
Some of the examples are from the Proto-5, others from the Proto-6 version of the old model. In the documentation section, all recent Business Aspect Servers will be detailed.

Some Interesting Sample Aspect Servers by Fredrik D. Alink (3-7-1996)
Overview
Stock Control Services
From the Retail demo. Stock Control looks to Business Objects from the aspect of their quantities being available in some way or another.
It's a context defining type of aspect.
Store Control Services
From the Retail demo. Store Control looks to Business Objects from the aspect of the place where they are "positioned" (i.e. stored). These do not need to be physical locations, any structuring that fits will do.
It's a context defining type of aspect.
Resource Control Services
Resource Control looks to Business Objects from the aspect of their usage as "resource" in the model. An obligatory resource is that of the "actor" responsible for the performance of a task. Any properties and preferences of a resource are defined here.
This is both a context defining type of aspect and an object defining type of aspect (i.e. all types of real resources - persons, computers, engines, whatever - are maintained by this Aspect Server).
User Type Control Services
User Type Control looks to Business Objects from the aspect of their responsabilities and authorizations on a type-level.
This is a context defining type of aspect, mainly referring to Resource Control Aspect Server defined Business Objects.
Scheduler Control Services
Scheduler Control looks to Business Objects from the aspect of them being scheduled in one or more "queues" of one type or the other. Within this aspect, all types of queues can be defined, maintained and used.
Essentially this is a context defining aspect with a very dynamical character.
