The Google Social Graph API-the good and the bad

Via John Breslin
" I was very interested to hear about the launch of Google’s social graph API at the weekend. The social graph API “returns web addresses of public pages and publicly-declared connections between them”, where the connections are currently being obtained from crawled XFN and FOAF links. Dan Brickley , the co-creator of FOAF said:

The Google API looks like a step in a very interesting direction. Of course it will be possible to think of many things it doesn’t yet do, but I encourage everyone here to have a think about simple, practical and useful incremental improvements to it. We can do a lot more eg. with full SPARQL access, but proving full SPARQL to the aggregation of the planet’s public FOAF/XFN data isn’t going to happen anytime soon. Interesting times

In answer to Niall Larkin ’s question about how this relates to SIOC , such services help us because by providing an easy method to find one’s social graph (both “me” and “knows” connections), it also makes it easier to find your social objects which can be described using SIOC (see my previous illustration , and see also Kingsley Idehen’s demonstration of how this can work).
In short, you can use FOAF to create the social graph, and use SIOC to represent social objects."
