Semantic Web Cluster Talk / DERI, NUI Galway / 27th April 2005

1. Problems
• Some class names conflict with FOAF
• RDFS limitations in parent_of term, as
Posts could be parents of Forums
• For each new User type, a new property
has to be added (Site →
has_administrator → Administrator)
• Temporal items outside our scope?

2. Solutions (1)
• Subclasses of Forum, Post, User removed
• Role class added and has_ (admin /
moderator / subscriber / participant …)
User properties dropped
• New type property added to Forum, Post,
Role to replace these subclasses /
properties
