“Architecting and Developing Message-Oriented Web Services” WWW2005 Tutorial
May is fast approaching and Jim and I have been starting thinking about the details of our WWW2005 tutorial on architecting and developing message-oriented Web Services. In the original proposal we had suggested that we were going to use WSE 2.0 for the discussion but now that the Avalon/Indigo March CTP is available to everyone,…

Vodafone’s vision
I thought that some of the proposed directions were obvious but the delivery is great. (via Radovan)

WSDM as a standard – the other side
The commentary from Tim Bray (“Stop WSDM”), Grek Pavlik (“WSDM Standardization: Just Say No (For Now)”), Mark Little (“Why WSDM isn’t ready for primetime (yet)”), me, and I guess others made Mark Potts reply (“Response to Stop WSDM”). First, my apologies to Mark for the lack of support for formatted comments on my blog. He…

Random thoughts on Robert’s random thoughts
In a discussion over at Sam Ruby‘s blog and on his “Distributed state machines” post, Robert Sayre made a random thought which I find intriguing. In a service-oriented world, like that promoted by MEST, where integration between services happens through metadata-sharing about the services’ messaging behaviours (described in languages like SSDL), could such route-finding algorithms…

WS-Web (The Web using SOAP:-)
Just joking… I haven’t come up with yet another specification. While travelling to Seoul, however, I was thinking about the on going discussion on REST vs SOAP. This is my small contribution to this discussion: An implementation of the ‘Web’ using SOAP 🙂 Background reading Lately the REST and SOAP folks have been busy arguing…

MyLifeBits video
I’ve known about the MyLifeBits work for some time now. We have even had brainstorming sessions here in Newcastle on how we can relate future research work on large-scale distributed systems with the excellent work that Gordon Bell and his team are doing. The project is presented in this Channel 9 video (first part). Worth…

Off to Korea and writing plans
I am off to Seoul, Korea tomorrow for GGF 13. I am not particularly thrilled about it since the meetings have become more and more boring due to the politics and the uninteresting technical work that is taking place there. The Grid application domain folks decided to build a Web Services infrastructure (WS-RF) and base…

This is why people have stopped believing in standards
The OASIS WSDM TC has decided to submit the WSDM specifications as an OASIS standard despite the negative vote. This is really bad for Web Services standards. Greg Pavlik blogged about what has been happening in the TC (post 1, post 2, post 3). I totally agree with Greg. How can we possible have a…

Implementation of WS-Transfer
Yesterday I was chatting with my friend Marty about WS-Transfer and the fact that we weren’t aware of any implementations out there. So, I challenged myself to write one in 30 mins using WSE. Well… it didn’t take 30 mins but a couple of hours because of a stupid bug related to WSE attributes… I…

WS-Trust and delegation
A discussion often taking place within the Grid community is the Grid Security Infrastructure (GSI) and the use of modified X.509 certificates for delegation scenarios (RFC 3820 – “Internet X.509 Public Key Infrastructure (PKI) Proxy Certificate Profile”). Not everyone agrees with the approach and, hence, the use of GSI sometimes means non-interoperable solutions. Credential-delegation, however,…
