Tim, In my view, 'invalidated' has different semantics to 'supersedes/superseded'. Besides domain and range restrictions may rule it out. Noticed that inverse property assertion is not stated on one of the properties.

When something is superseded it no longer should be referred to. Whereas when something is a revision of something else all versions my still be valid. We see this in many document-centric environments. For example at NASA, a specification for telemetry and commanding of vehicles existed in a number of concurrently valid revisions (REV A, REV B, etc.). Each revision having justification in specific contexts-of-use. Moreover 'supersedes' and 'supersededBy' are very commonly used at W3C. >> >> Ralph Hodgson, @ralphtq >> >> Mobile Phone: +1 781-789-1664 >> >> CTO, TopQuadrant, @TopQuadrant >> >> Blog: Voyages of the Semantic Enterprise >> >> Newspapers: SPARQL, SemanticWeb, LinkedData >> >> >> >> >> >> On Nov 2, 2012, at 2:27 PM, Paul Groth <pgroth@gmail.com> wrote: >> >>> Hi Ralph, >>> >>> Would wasRevisionOf be of use?
