Abstract
In this paper we present Structured Belief Bases (SBBs), a framework to reason about belief change. Structured Belief Bases can be considered as a special case of prioritised base revision, where the components of the base are allowed to be structured bases as well. This allows for the representation of complex levels of priority between sentences. Each component is resolved into a sentence via a revision operator taking the ordering into account. By adopting a right associative interpretation of the operator we avoid many of the problems with iteration faced by revision operators complying with the AGM postulates. New beliefs can be accepted by simply incorporating them into the base with highest priority.
