		<description>@Ian that&#039;s definitely also interesting and I just  posted about possible hCard support in Plone. It might also be nice to have a general microformats parser in Python 
 
@Guido yep, it makes sense to extend them and if you want to go for it, feel free to do so. I&#039;d suggest though that we model the graph as objects then, e.g. 
 
graph = SocialGraph(url=&quot;http://mrtopf.de/connect&quot;) 
friends = graph.friends 
paul = friends[&#039;paul&#039;] # paul might be the nickname defined in hCard 
pauls_profiles = paul.profiles 
 
and so on. Maybe support for symmetrical relationships could also be added that way to filter out just these. 
 
I also wanted to make them an egg btw and was wondering if the eventlet support can be made optional in only one file. 
 
@Reinout definitely makes sense. The idea behind my page was though to collect all those links in one page and as they are quite a few not to pollute the blog with it. But theoretically the spider should follow the homepage link to the connect page (must be marked as rel=me) and then find the links there. Of course it&#039;s not directly symmetrical but only indirect. I wonder if that makes sense ;-) 
 
Then again my homepage is only a picture now anyway so why not add links and contact information to them. </description>

		<description>On saturday I put a new front page online for my &lt;a href=&quot;http://vanrees.org&quot; rel=&quot;nofollow&quot;&gt;http://vanrees.org&lt;/a&gt; site. In the lower right part I list all the flickr-linkedin-twitter type links. With xfn rel-tags. 
 
So that&#039;s only a listing of my own pages. I did deliberately use my frontpage for that, as it makes it easier to get bi-directional links. On linkedin, I just link to my front page and the front page itself links back. No separate contact page. </description>

		<description>Nice, Christian. This code just /asks/ to be extended into a generic rel=&quot;*&quot; parser that stores the social graph it discovers into a zc.relationship index... I hope to find time to play around with this stuff soon. </description>

		<description>I&#039;ll check that Google Code URL again, looking forward to seeing what you&#039;re posting there. I&#039;m also interested in seeing FOAF, XFN, hCard and OpenID link tags used for identity federation.
