Solution:SPoX – Skype Policy Extension: Reactive SemanticWeb Policies based on Social Semantic Web data
• User can set up reactive policies in an Event-Condition-Action fashion
• Decisions can be based on– Social Semantic Web data (FOAF, DBLP)– Proprietary Social Network APIs
(Twitter, Flickr, Skype)• Behaviour of Skype is driven accordingly via
Skype's Java API• Advanced policy negotiations are carried out over
the Skype application channel• Allows for digitally signed credentials• Based on a rule based policy engine (Protune)
Problem:• Skype client offers only limited control about
who can call you, which chats get through, which notifications show up
• It considers only “Skype friends” – but what about the friends on Flickr, my followers on Twitter, my FOAF friends?
• No way to automatically react to calls(e.g., forwarding, cancelling)
