LADA — A Logic for the Analysis of Distributed Actions
This paper presents a formalism, LADA, aimed especially at the description of systems and situations which arise during the design and analysis of groupware. We are particularly interested in highly distributed systems and so LADA explicitly models entities (people and things) acting at different unconnected locations. It not only describes the behaviour of the computer software, but also the social protocols required for its successful use. Temporal logic formulae which follow the subjective history of people and other entities are used to simplify the expression of some of the complicated properties required of real systems.
