After listening to Garrett's (and friends) presentation at MIX07 on CardSpace, my eyes were opened to the new wave of business opportunities that the identity metasystem will give.

The presentation cited a new Canadian business that are using managed cards providing claims that captured in formation about people's body sizes.

Users can use these managed cards to sign in to sites selling clothes, and then they would can be directed to clothes that fit their body shape. Also, the users can use models to visualise what the clothes would look like when worn.

This is a very simple example of how claims based systems can create new businesses and enhance the offering of existing businesses to the consumer.

Today my blog would not accept my Information Card when I tried to log in.

I got this error: The SamlToken is not time valid. The current time '5/7/2007 1:57:23 PM' is outside the Effective '5/7/2007 2:02:27 PM' and Expiration '5/7/2007 3:02:27 PM' time of the token.

The system is checking the validity of the two systems that are working with the SAML token.

Make sure your sever has the right time and timezone set, otherwise users will not be able to authenticate.

The Pamela Project is a group of people that are building plugins and additions for existing web site frameworks that add CardSpace support.

This is a great initiative, along the lines of the work that I have been doing for DotNetNuke.

Here's a great presentation delivered by Garrett Serack at MIX07.

Garrett demonstrates Microsoft's latest CardSpace reference sample, and the CardSpace patterns outlined in my last post.

Microsoft have published a new document based on upcoming samples that show the standard requirements for implementing CardSpace and the Identity Metasystem in a web application.

This is the pattern that I have followed to create the CardSpace DotNetNuke Module.

Thanks to Mike Jones for announcing this: http://self-issued.info/wp-trackback.php?p=6

dbartholomew.net now supports two types of Information Card.

This portal, http://www.dbartholomew.net, supports self issued cards.

http://www.dbartholomew.net/managedcards supports cards issued by the Live Labs STS.

Unfortunately dbartholomew.net has been offline for a fwe days due to server problems.

Sorry for any inconvenience, this has not been 100% resolved at this stage as the system is not currently enfocing SSL on CardSpace pages.

This will be corrected shortly.

Since I was privileged enough to work with Steven Woodward in January I have thought about many of the things he taught me, but nothing as much as his Eighth Law of Identity - "There must be something in it for everyone".

I've been trying to work out why there isn't much momentum in the CardSpace world - when compared to the WPF's, the WCF's and WF's of .Net 3.0.

I wonder what is missing, and the only thing I can come up with is that the success of CardSpace, and in turn the Identity Metasystem, relies on sales of Vista.

However, I find this to be a bit of a "Chicken and Egg" problem - why would people move to Vista (or install the .Net Framework 3.0 on XP) if web sites are not implementing CardSpace? Why would web sites invest in enhancing their systems when the potential user base is so small?

I think that out of the .Net 3.0 technologies, CardSpace will have the most important impact on the Internet ...

This screencast is everything you need to know to prepare a development envinronment for CardSpace. Richard Turner surely knows his stuff.

It also solved the problems I had when I setup www.webhost4life.com to read CardSpace tokens.

It also provided me a nice entry into PowerShell - I don't see any reason to use Start -> Run > Cmd again.

Thanks Richard!

I've created a CardSpace example at https://www.dbartholomew.net/ajax_example/

You can submit an Information Card, and you'll see the data from the InfoCard displayed. Notice the page doesn't refresh, as the time doesn't change.

I'll post code and a screencast of this work on www.readify.net soon. If you want more information, then contact me through the contact page - or, leave a comment!
