Planet contains general, domain-independent definitions that are common and useful across planning domains. Third, Planet can facilitate integration of planning tools through knowledge sharing. These difficulties are in part because these systems include decision-support tools such as plan editors, plan evaluation tools, and plan critiquers, which represent plans in ways that are different from traditional AI plan generation systems. Planet can provide a shared plan representation for systems to communicate and exhange information about the plan, and can facilitate the creation of a common, overarching knowledge base for future integrations of planning tools. Planet is still under development, and we would appreciate your comments.
Planet is a middle-level theory that represents planning knowledge.
A short note on the integration work is available as an internal project report here . We also use Planet in our work on a problem-solving method for plan evaluation .
