FEDERATED IDENTITY AND DELEGATION WORKSHOP FOR OGF37
by OGF Events 31 Jan '13

31 Jan '13

Federated Identity and Delegation Workshop- Monday March 11, 2013 Delegating attributes and identities as a means of establishing who, or on whose behalf, an operation is to be executed, is a concept as old as the access matrix. The basic problem is of asserting in a cryptographically secure way that A->B (A says that B is authorized to act as A) and subsequently have B->C and C->D such that A->B->C->D, i.e. D is authorized to act as A. The challenge in multi-organizational distributed systems such as clouds and grids is particularly difficult due to the different mechanisms and policies of the various players. Existing mechanisms include, but are not limited to, X.509 delegated credentials, VOMs certificates, and signed SAML assertions. The goal of the workshop is to bring together stakeholders in the scientific computing infrastructure community in the Americas, Europe, and Asia to present requirements for a good solution to the delegation problem, alternative visions of how this problem can be solved, and begin the process of defining a limited number of interoperable common mechanisms. Following the workshop the OGF Identity Delegation working group (IDEL) will meet to continue the work of identifying and defining proposed standards and best practices for grid identity delegation.

CALL FOR DEMONSTRATIONS FOR OGF37
by OGF Events 31 Jan '13

31 Jan '13

Call for Demonstrations The organizers of OGF 37 invite software teams to demonstrate cloud and grid infrastructures, software systems, and applications at the Open Grid Forum 37, March 11-13 in Charlottesville Virginia. These 75-minute demonstrations will be held concurrently on Tuesday, March 12. During the demonstration period, each team will give its presentation three times, with a 5 minute break between sessions. Participants will attend a demonstration of their choice for twenty minutes, have five minutes to move to another demonstration, see a second demonstration, and then move again to observe a third demonstration. This format will allow attendees to see three different demonstrations and will give demonstrators a reasonable period of time to present their project. Each demonstration team will be provided with a conference room (small rooms hold 10, larger ones 15), projection system, Ethernet, and Polycom phone system if needed. To apply for a demonstration slot, please send a half-page abstract by February 15, 2013 to glc2z(a)virginia.edu. The abstract should clearly state the problem the software addresses, the OGF standards, if any, that are supported, and what attendees can expect to learn. Gina L. Corell, Ph.D. Communications Director The University of Virginia Alliance for Computational Science and Engineering UVACSE 434-243-1107 http://www.uvacse.virginia.edu/

Dear Open Grid Forum Working Group members, The Open Grid Forum (OGF) is organizing its 37th global conference on 11-13 March, 2013 at the University of Virginia in Charlottesville, Virginia. It is our first event of the year and as such we would like to have an especially powerful and productive impact. Not to mention that Charlottesville will be beautiful in the spring and traveling to Charlottesville is also extremely affordable. From any of the major airports in Europe, flights average 675 Euros and hotel rooms average 110 Euros per night. OGF conferences offer open forums that build the community, explore trends, share best practices and consolidate these best practices into standards. The OGF conference will be filled with many speakers, along with information-packed workshops and will be attended by leading business, government, The registration form and the detailed schedule, containing information about the speakers and programs can be found on the official OGF37 website (http://www.ogf.org/OGF37/) See you in Charlottesville! Sincerely yours, The OGF Team

New document published: Web Services Data Access and Integration – The RDF(S) Realization (WS-DAIRDFS) RDF(S) Querying Specification, Version 1.0
by Greg Newby 15 Jan '13

15 Jan '13

OGF Community: A new document has been published in the OGF series. All OGF documents (including any that are open for public comment) may be found here: www.ogf.org/gf/docs/ * GFD-R-P.200 "Web Services Data Access and Integration â€“ The RDF(S) Realization (WS-DAIRDFS) RDF(S) Querying Specification, Version 1.0," I. Kojima, S. M. Pahlevi, S. Lynden, via DAIS-WG. Abstract: Data resources play a significant role in many applications across multiple domains. Web services provide implementation neutral facilities for describing, invoking and orchestrating collections of networked resources. The OGF (Open Grid Forum) Open Grid Services Architecture (OGSA), and its associated specifications, define consistent interfaces through web services to components of the grid infrastructure. Both the web and grid communities stand to benefit from the provision of consistent and agreed web service interfaces for data resources and the systems that manage them. This document presents a specification for a collection of querying interfaces for RDF(S) data resources, which extends interfaces defined in the Web Services Data Access and Integration document [WS-DAI]. It also presents interfaces for handling RDF graphs in RDF(S) data resources. This specification can be applied in regular web services environments or as part of a grid fabric. -- Greg Newby, OGF Editor Dr. Gregory Newby, Director of the Arctic Region Supercomputing Center Univ of Alaska Fairbanks-909 Koyukuk Dr-PO Box 756020-Fairbanks-AK 99775-6020 e: gbnewby(a)alaska.edu v: 907-450-8663 f: 907-450-8603 w: people.arsc.edu/~newby
