Deadline for Special Issue

/**/ Since my last post about the JWSRspecial issue on the Web Services Architecture, we had a couple of requests for extension. So I think that it’s only fair to give an extension to everyone. However, due to the tight schedule for the reviewing process we can only allow for …

Stateful services (yes, again!)

There was a question on “stateful Web Services” over at the w3c-ws mailing list. Of course, I couldn’t resist not making a comment :-) However, I used a politically incorrect phrase about the demise of OGSI (“miserable failure”) and I think that got me in trouble again :-( I should …

Yes, WSE 2.1 please!

Please Microsoft. As Clemenssays, we need WSE 2.1 with an updated version of WS-Addressing to match the current spec. I’ve stopped my WS-Eventing implementation because of that reason. Read more [...]

On wsa:action

/**/ While reading the 3rd part of the factored WS-Addressing spec, it occurred to me that the discussion on how to associate wsa:action headers with messages in WSDL operations or how to implicitly generate them could be simplified by having just a uniform action for all SOAP messages: wsa:action=”process:message” Anything …

“Can OO be SO?” by Tim Ewald

Commenting on Clemens Vasters’ post, to which I linked in my previous entry, Tim Ewald remembers (“Can OO be SO?”) that at the last PDC someone had asked Don Box about the use of EPRs as CORBA IORs :-) Back then (October 2003) rumours were surfacing about some work IBM …

I am not alone after all

Here’s a post by Clemens Vasters saying what I’ve been saying for some time about the use of WS-Addressing as an object pointer :-)

Deadline for the special edition is coming

The deadline for the special edition on Web Services Architecture of the Journal of Web Services Research is very close now. If you are thinking of submitting a paper but would like some more time, please drop me or Jim a line.

Spot the difference

I just spotted the “spot the difference challenge” (sorry Mark)… I’ll bite. What’s the difference? I don’t personally see one. The ProcessMessage “operation” is all about processing of messages. It’s all about an agent sending a message to another agent for processing. The introduction of this logical operation into the …

Building blocks of architectural paradigms

/**/ Since the publication of WS-Transfer, the discussion on REST vs WS has been intensified. Just google the terms and you’ll find lots of commentary. I would like to start this entry by just saying that comparing REST and Web Services technologies is like comparing apples and oranges. One is …

What makes a SOAP document a message

/**/ Mark Baker comments on Steve Maine’s “Web Services Kernel” post and says: “A SOAP envelope is not a SOAP message, and pretending otherwise turns a perfectly good document wrapper into a perfectly crappy application protocol.” Hmmm… I think Mark makes a good point but I also believe that it …

Jim’s article on “Why WSDL works”

/**/ I haven’t been bloging lately. I’ve been coding like crazy my WhiteDwarfs application. I’ll try to release something within the week. I’ve also been collecting some thoughts on resources vs services vs objects that I am going to blog about soon. In the meantime here’s a reference to Jim’s …

Back home from a knee operation

Yesterday I had an operation on my knee. Everything went fine. Just got back home. Now some serious physiotherapy for few months. Hopefully, I will be able to ski again next year :-)

EPL

The EPL language for implementing event-based solutions using a declarative language. Interesting.
