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…

MSN Spaces
I like this. The customisation options are really cool. My space is at http://spaces.msn.com/members/savas/. My concerns are: My current blog already has permanent links that I don’t want to loose. I don’t have complete control of my space. I am not sure whether I will be charged in the future for the service. I can…

RDF to filter WS-Eventing notifications?
This is an interesting proposal. As Stefan (needs to sort out main page) says, WS-Eventing allows the use of any dialect for filters, so why not RDF? (Disappointed that my implementation efforts are not listed 🙂 (just joking of course).

I find myself agreeing with Steve on this
In addition to defining addressing-related information headers for SOAP messages, WS-Addressing introduces the concept of an EndpointReference (EPR) which is used as the means of capturing the addressing-related information of a service endpoint. I don’t see why an EPR couldn’t be of the form: <wsa:ReplyTo> <!- Protocol-specific addresses -> <wsa:Address>http://service.com/myservice</wsa:Address> <wsa:Address>corba:bla-bla-bla</wsa:Address> <wsa:Address>tcp-ip:123.123.123.123</wsa:Address> <!- And a…

A paper on “When Database Systems Meet the Grid”
“To our knowledge, most of the data-intensive applications that run on the Grid today focus on moving hundreds of thousands of files from the storage archives to the thousands of computing nodes.” [1] The above quote is from [1] which is written by the team that has given us the SkyServer. Talking to Maria recently…

Tutorial on WS at WWW2005
Hurray! Jim and I submitted a proposal for a tutorial on “Architecting and Developing Message-Oriented Web Services” for the 14th Internal World Wide Web Conference (WWW2005) and we have just found out that it got accepted. This is going to be a lot of fun. We have some really great ideas on how to approach…

Globus to become part of Apache?
I saw this submission/proposal by Globus over at aparche.org. The Globus Alliance is proposing the creation of an Apache subproject for Grid computing with the Globus Toolkit as the basis. My first feeling was that this could be a good development for the Grid community but then I thought about the issue of standards and…

Making WinFX work on a non-Luna themes
In one of the WinFX CTP articles it is noted that only the Luna/NormalColor theme is supported. In order to work with the other WindowsXP themes, there is a workaround. I just discovered that this workaround works with different themes too. On my laptop I have the Royale theme installed (yes, I know it’s only…
