Abstract

The ability to express temporal conditions, like for example deadlines, is extremely important in agent applications. Nevertheless, communication standards like FIPA ACL do not outline a uniform way to specify such conditions in Content Language expressions. In this paper we extend a CTL*-like temporal language with two very expressive interval operators, and integrate it with a FIPA-compatible representation of dates. We then show, by a number of selected examples, that the resulting language allows agents to express a rich assortment of temporal constraints in a very natural way.
