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,…

WinFS to be ported to WinXP?
That’d be cool. The article is questioning whether there would be value in upgrading to Longhorn if all of its pillars are available for Windows XP. I speculate that Microsoft will be first offering consumers an intensive to upgrade by offering a new user experience (Aero, new driver-support, multimedia device integration/support, OS componentisation, etc.). The…

Technology fanaticism vs enthusiasm
In the past, I too have been responsible for fuelling OS and platform related arguments. However, for quite a few years now I realised that the choice of a tool is a personal matter. In the same way I don’t try to push to people my favourite programming language, IDE, OS, laptop, hardware vendor, bookstore,…

SSDL in “Architectural Styles for Web Services”
This short article on “Architectural Styles for Web Services” mentions SSDL and MEST. Jim Alateras demonstrates how a simple Web Service could be described using WSDL, implemented using HTTP, and described using SSDL.The problem at hand makes SSDL look remarkably similar to WSDL. Indeed, the equivalent SSDL would be something like this (using the MEP…
