Backnetwork Lab – XFN pagination
Few weeks ago I watched Tantek Çelik give a demonstration of the Plaxo open social graph which is basically a rel=”me” spider. It reminded me how powerful practical demonstrations are at communicating key concepts.
So I have built lab.backnetwork with the idea of constructing a number of service based interfaces which are practical demonstrations of key concepts that are currently under discussion.
I am really interested in focusing on the portable social network area, so I have start with a very simple example of XFN pagination using rel="next". I am hoping to fellow this with a second interface which can parse the XFN/hcard pattern.
XFN pagination interface
Given any Url it will parse XFN relationship links within a page and then fellow
any additional links that have the rel=”next” attribute. I have limited system
to only spider 20 pages at a time. I have provided two set of test pages with
different pagination patterns.

Simple pagination design pattern where the user is viewing pages 2 of a set.
Pages: <a href="page1.htm" rel="prev">1</a> 2 <a href="page3.htm" rel="next">3</a>
The interface will work with any site, but at the moment there are very few if
any site which use rel=”next”.
