Easiest explanation: KAoS policy language expresses and applies policies in the software agent context. It was initially based on DARPA Agent Markup Language (DAML) and eXtensibleMarkup Language. But due to poor descriptive logic of DAML, KAoS shifted towards the Web Ontology Language to represent knowledge about domains and rule-based policies.
