Future of OGSA, Web Services in Hands of IT Community
by Hiro Kishimoto 13 Jun '05

13 Jun '05

Mark Linesch's article in GRIDtoday. Grid computing is increasingly being viewed as a critical component of the next phase of distributed computing. The key to realizing the benefits of Grid computing is standardization, so that the diverse resources that make up a modern distributed environment can be discovered, accessed, allocated, monitored and, in general, managed as a single virtual system -- even when provided by different vendors and/or operated by different organizations. Standardization of Grid computing is being led by the Global Grid Forum (GGF). GGF has developed the Open Grid Services Architecture (OGSA) and is working throughout the international community to champion this "architectural blueprint" and the associated specifications that will enable the pervasive adoption of Grid computing for business and research worldwide. http://news.taborcommunications.com/msgget.jsp?mid=396791 -- Hiro Kishimoto

Roadmap v11 and standards tracking spreadsheet uploaded
by Treadwell, Jem 11 Jun '05

11 Jun '05

Hi, My mind is now clinically numb. I've uploaded a new roadmap, with changes as agreed on Monday - see the markup for significant changes. All standards tables are now pictures, pasted from the new standards spreadsheet, which is uploaded to the same folder. I won't try to describe the spreadsheet as we discussed it on Wednesday, but it is worth browsing. Having spent the past few hours getting the first set of worksheets set up, it *is* tedious to work with, but copying the sheets into the document is simple (though also tedious for this particular document!), and I can't think of a better way to do it right now. I'm very open to suggestions for improvements/simplifications to the spreadsheet. We *do* need to review some of these versions etc. - e.g. RNS versions of WS-Addressing and WS-ResourceProperties are not in line with the RNS document. But for now I'm going to leave it alone. If anyone wants to make some updates, I promise not to do anything else before Monday's call, so you can grab the pen. Thanks to all who responded for this version; everyone enjoy the weekend. Oh, and the documents are both at http://tinyurl.com/aez86. - Jem ________________________________ Jem Treadwell Hewlett-Packard Company 6000 Irwin Road Mount Laurel, NJ 08054 Phone: 856-638-6021 Fax: 856-638-6190 E-mail: Jem.Treadwell(a)hp.com <mailto:Jem.Treadwell@hp.com>

Questions on OGSA WSRF Basic Profile 1.0
by Mark McKeown 10 Jun '05

10 Jun '05

Hi folks, Sorry if these are dumb questions... I was looking through WSRF Basic Profile 1.0, (Revised: Friday, June 10, 2005). > Section 9.1.1 Mandated Secure Transport "All messages are subject to interference and corruption during transmission. The Profile mandates secure transmission of messages." Is there a reference that makes this case? I have looked at the WS-I document "Security Challenges, Threats and Countermeasures" http://www.ws-i.org/Profiles/BasicSecurity/SecurityChallenges-1.0.pdf which indicates that message level security is OK for many threats. WSRF & ACID Section 7 of Web Service Resource Properties 1.2 discusses ACID and WSRF - a WSRF implementor can choose a concurrency policy with regard to updating and retrieving resource properties, so two implementations of a WS-Resource with the same operations and PropertiesDocument could actually have different behaviour leading to interoperability issues for clients - is this any area for a WSRF profile to address? thanks Mark ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mark Mc Keown RSS Mark.McKeown(a)man.ac.uk Manchester Computing +44 161 275 0601 University of Manchester ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

RE: [ogsa-wg] Teleconference minutes - 8 June 2005
by Djaoui, A (Abdeslem) 10 Jun '05

Just a comment of the WSRF BP submission to the GGF editors. I am in favor of option 1 simply because I don't see a point of releasing a profile that "very likely" nobody is going to use. I know there are some implementations of the referenced specification out there, but in my view people will find it more efficient to move to the latest versions of the specifications that to try to be compliant with an older version of a profile that is going to be changed soon. Anyway the wait is almost over!
