As I have mentioned before, there has been a lot of discussion of late within the Identity Gang around “What is user-centric identity” and “Where does it fit into the enterprise”. One of the battles I have had in my own mind is understanding where all the different technologies protocols, frameworks etc (Card Space, XRI, OpenID, LID, YADIS et al) fit into the equation.
It seems that I am not the only one. Drummond Reed has recently being fighting with exactly the same problem. Following on the from the Berkman Identity Mashup he posted a very enlightening blog explaining his understanding of the difference between i-cards and i-names. There are some really good examples in here.
Good post Drummond!
