What does “WS-I compliance” mean?

/**/ Ever since we published our WS-GAF white paper criticizing OGSI, its object-oriented nature and how it (ab)used existing technologies (XML Schema and WSDL), there has been a lot of discussion in the Grid community about WS-I. You see, we’ve always advocated for Grid solutions to be built on stable, …

The 3D star browser in our VR facility

/**/ Old readers of my blog will know that I have been experimenting with Avalon by building a 3D star browser using the Sload Digitial Sky Survey data. I have ported the previous version of the StarBrowser to the Avalon March 2005 CTP but my laptop’s hardware cannot really cope so …

MEST music

This may be an album I may buy. I just happen to like the name of the group :-)

Steve, Mark, and Stefan on REST/WS

The discussion on REST/WS is still very much alive. There is an interesting thread of comments in Steve Vinoski’s “WS references” post. Note the references to “ProcessThis”. I wouldn’t have made the link between “ProcessMessage/This” with protocol handlers or interceptors in the same way that REST doesn’t link the transfer …

MEST, an operation, and the role of contracts

The discussion on MEST started again thanks to a recent entry by Jim. Mark makes some valid observations in his comment to Jim’s entry. I would like to clarify a couple of things: MEST is an architectural style and as such it is not tightly associated to SOAP. The relationship …

Remotely logging Indigo messages using Indigo

/**/ I had a couple of hours available while travelling by train to London the other day, so I decided to play with Indigo’s message logging facility. Indigo does a great job of logging in/out SOAP messages to/from services. Check the TracingAndLogging sample that comes with the WinFX SDK March …

A generic class for implementing protocol handlers in Indigo

/**/ In my “Indigo adventures” post I showed how one could write a new channel which can be used to implement a WS-* protocol. After watching the Indigo SDR content, I still think this to be the recommended way of implementing an infrastructure protocol (even though I am still not …

Indigo SDR content

All the content from the last Indigo Software Design Review (SDR) is now available online. I wish I knew about this before getting inside Indigo on my own. But then again, I wouldn’t have had the fun of finding problems that needed solving :-) I am starting to go through …

Indigo adventures

/**/ Those interested in Indigo would have probably seen by now the many introductory posts on how to write services, use bindings, use output/input channels, service/message/data contracts, etc. The Indigo community is doing a fantastic job to provide examples of how to use Microsoft’s new technology for distributed computing. As …
