Multi-layer markup and ontological structures in Akoma Ntoso

The XML documents that represent legal resources contain information and legal knowledge that belong to many distinct conceptual layers. This paper shows how the Akoma Ntoso standard keeps these layers well separated while providing ontological structures on top of them. Additionally, this paper illustrates how Akoma Ntoso allows multiple interpretations, provided by different agents, over the same set of texts and concepts and how current semantic technologies can use these interpretations to reason on the underlying legal texts
