Our customer would prefer the use of XML documents over SVN Properties. For this the ConferenceDataAdapter class needs to be adapted.
It would be nice if the properties of a conference or paper could be added from the GW interface. For this one would need a special style sheet and a new set of permissions for viewing, editing, adding and removing of these 'properties'. Note that if combined with the above feature, this would apply for 'property xml files' only and then there would still be no way to view/edit SVN Properties
Further integration with the existing wiki system, see this diagram with some proposed changes.
