RE: [xdi] updated link contract support

Markus,

 

Great stuff. I’ve been in London at
the OASIS Open Standards Forum all this week – I’m speaking on XDI
and relationship cards tomorrow – so I won’t be able to look this
over until next week when I’m back in Seattle. But if you’re
available, let’s plan on having a demo of this on next week’s
telecon.

 

Best,

Subject: [xdi] updated link
contract support

 

Hello,

I updated support for XDI link contracts in XDI4j according to the pattern at http://wiki.oasis-open.org/xdi/XdiOneIssues/LinkContractPattern.

There is no separate demo application for this, because link contracts are
really a part of XDI messaging. The best way to experiment with them is the XDI
Local Messenger. This is an application that applies the XDI message in the
right text area to the XDI graph in the left text area:

http://graceland.parityinc.net/xdi-localmessenger/XDILocalMessenger

If you simply click "Go", you will see that everything works. But if
you enable link contracts, you will get an error, because the message is not
allowed under the existing link contracts. As an exercise, you can try to
modify the link contract in the left text area, so that the message succeeds
again :)
