# Benefits of Dereferenceable URIs
Just a simple post, I don’t want anything too complex because Dereferenceable URIs are actually really simple to understand.
I’ve been working on the Dereferenceable URI’s page on Wikipedia, and I started writing a section which I thought I would share with you all here as it is so important… it’s about the Benefits of Dereferenceable URI’s:
When an object has a dereferenceable URI, not only does that object have an insignia that can be used across the web, but it also provides a key to unlocking ways of providing more detail and links to relevant information about that object.
Dereferenceable URI’s used in this way also enhance OpenID, when not only can the URI be an OpenID but can also provide information about that agent user. The combination of insignia, access to more information and OpenID provides an all round solution for the representation of human users on the Internet.
(note that the above will probably get edited on Wikipedia a few times, but here is the essential information)
I do very literally mean the above. I have a web insignia (which is similar to a graffiti tag, but on the web and provides a bit more (continue reading)), which also provides the key to my public information and is also my OpenID.
So when I go to a site, I should be able to login using my unique tag (as an OpenID)… that site can then get information about me in order to provide a visualisation of my profile so that other people can see that I have presence in that location. Also, when I am writing on my blog or writing a comment on a forum or someone elses blog then I should be able to tag it with my insignia… like I’ll do below
