FOAF hacks of the day

A bit of hacking tonight, after a lot of interesting talks this afternoon about FOAF, OpenID and online identity (and certainly more to come tomorrow):

• Added queries to retrieve user accounts from FOAF profile and display them in comments with SparqlPress. Once again, it’s done by SPARQLing the FOAF URI of the user logged-in on this blog using an OpenID URL. To be displayed, the account must either have a URI (i.e. not to be a blank node) or a foaf:accountProfilePage (BTW, this one is not in the specs while it seems most people agreed on it - and already use it. Dan, what about it ?). Also added icons for some well-knows services. Live example here, and screenshot:

• Updated the simple network browser script to be compliant with the new release of a GraphGear (1.2). The component has new interesting features that can be set in the xml file, as setting the size of the nodes, and adding images. I updated the script to benefit from those features, and so it now display pictures and smaller nodes, which make the script run faster. The image detection only handles foaf:img at the moment, so this is something that whould need more work (e.g. retrieve sioc:avatar from the related online account …). Yet, here’s a sreenshot of the new rendering that you can browse there:

Time to sleep now …
