Metadata for Academic Event PIDs

This presentation takes a look at how academic events are being reflected in PID registrations and what kind of metadata are provided for them, focusing on the ten repositories registering most DataCite-DOIs with Resource Type General "Event". With metadata schemata not specifically tailored to academic events, how can PID metadata still distinguish academic events from other kinds of events, and from their output? In existing PID metadata, how well documented are the connections between events and their context, contributors, output, etc.?
