Loose-coupling through the relaxation of endpoint assumptions
In a meeting yesterday here in Newcastle, few of us (Santosh Shrivastava, Paul Watson, Mark Little, Stuart Wheater, Simon Woodman, and I) got together to discuss/understand the differences (if any) and similarities between service-orientation and object-orientation. You may notice that some of the people involved are the same as the ones behind Arjuna and have a long history in…

WSDL is a joke?
🙂 Web Services takes the world and “How many jokes have a WSDL as a punchline?” :-)) (via Matt). UPDATE: Here’s another one Seriously now… Your favourite WS advocates (I meant Jim and myself 🙂 are working on something in the WS description area and this time we have collaborators. Watch this space.

“Critics Say Web Services Need a REST”
Jim, amongst others, was interviewed on the REST vs WS debate (“Critics Say Web Services Need a REST”). Jim pushed the MEST ideas although not by name (btw… thanks for the reference mate 🙂 and I was glad to read Mark Baker’s comments suggesting that there may be something in what we are proposing, as he’s done…

“Searching for White Dwarfs” application
In previous posts I mentioned our “Searching for White Dwarfs” application which was aimed at illustrating how “typical” Grid applications could be easily built using existing Web Services technologies and tools.

EPRs and the architectural elements they address
But which are our architectural elements you may ask? Services or resources? I posted my thoughts over at the W3C mailing list. For those who have been following what Jim and I have been saying about OGSI, WSRF (and to a lesser extent about WS-Transfer), this post is a short summary. Expect more when we…

Using SAML for credential delegation
The paper on “Extending the Security Assertion Markup Language to Support Delegation for Web Services and Grid Services” by Jun Wang and my friend Marty Humphrey over at the CS department, University of Virginia, is a great read. It illustrates how one could do user rights delegation using SAML. This is a common scenario in…
