Ordering of Event Log entries

[phochste]

I 'm trying to create an ordering of event logs in the scholarly-broswer. In the artifact explorer I create to add a published property for event log member that all my example logs have. In the scholarly-browser I would like to see an ordering of events based on this publication date. But whatever I try the output seems unsorted.
