Subject: [refactoring] Discussion of OGSI and Web Services
Hello, I don't follow the OGSI WG email, but had this forwarded to me by a colleague at MITRE. I have to admit that I am not an expert on OGSI, but this isn't long and makes some interesting points that seem to relate to some of our own arguments. I deleted the attachment on the theory that the email itself has a URL where people who are interested can download it. It would be nice if those more involved in the OGSI can provide some informed commentary on this. Thanks. -- John DeCarlo, The MITRE Corporation, My Views Are My Own email: jdecarlo@mitre.org voice: 703-883-7116 fax: 703-883-3383 DISA cube: 703-882-0593

Dear all, (Apologies if you receive multiple copies of this message). There has been a lot of discussion in the community on the relationship between Web and Grid Services. Here at the North-East Regional e-Science Centre (NEReSC, http://www.neresc.ac.uk) and in collaboration with Arjuna Technologies (http://www.arjuna.com), we have been looking at the relationship between Web Services technologies, OGSI and Grid requirements. The attached document investigates the Grid architecture and its relationship to the Web Services Architecture. It presents our views on the current version of the OGSI specification and then goes on to propose a different mapping of the Grid infrastructure requirements to Web Services specifications and practises. The aim is to design an alternative mapping that captures the same Grid requirements, but fits more closely with conventional Web Services specifications and practises. It is not in our intentions to create an alternative to OGSI but, rather, provide an analysis of the issues with the current version of the specification and use it as input to future discussions within the community. This document is work in progress and will, hopefully, evolve through the feedback we look forward to receiving from the community. You can find the latest version of this document, along with more examples of the use of the proposed framework at http://www.neresc.ac.uk/projects/gaf. We are submitting the document to the relevant working group within the GGF as input to discussions on the future of OGSI. Regards, Savas Parastatidis, NEReSC Paul Watson, NEReSC Jim Webber, Arjuna Technologies Thomas Rischbeck, Arjuna TechnologiesA Grid Application Framework based on Web Services Specifications and Standards v1.0.pdf
