A Lightweight Treatment of Inexact Dates

This paper presents a lightweight approach to representing inexact dates on the semantic web, in that it imposes minimal ontological commitments on the ontology author and provides data that can be queried using standard approaches. The approach is presented in the context of a significant need to represent inexact dates but the heavy-weight nature of existing proposals which can handle such information. Approaches to querying the represented information and an example user interface for creating such information are presented.</p
