Abstract

TROLL light is a language for conceptual modeling of information systems. It is designed to describe the Universe of Discourse (UoD) as a system of concurrently existing and interacting objects. TROLL light objects have observable properties modeled by attributes, and the behavior of objects is described by events. Possible object observerations may be restricted by constraints, whereas event occurrences may be restricted to specified life cycles. TROLL light objects are organized in an object hierarchy established by subobject relationships. Communication among objects is supported by event calling.

TROLL light was employed for the specification of a production cell. In this paper we show some characteristic points of that specification and conclude with a discussion of lessons learned from this work.

Keywords

Event Occurrence Object Description Interaction Rule Object Community Object Hierarchy 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
