Re: [ogsa-wg] [OGSA-D-WG] Definition of "data service"
by Dave Berry 24 Jul '07

24 Jul '07

I attach the current glossary definitions from the OGSA Data WG. The definitions of data service & data resource are as follows: Data resource: An entity (and its associated framework) that provides a data access mechanism or can act as a data source or data sink. Data service: A service that provides interfaces to the capabilities and data of one or more data resources within a service-oriented architecture. When I adapted the OGSA 1.5 document to use the latest definitions from the OGSA Data WG, I realised we still needed a term to describe all the related services as well. The current proposal is to use the term "Data Management Services" (which mirrors "Execution Management Services"): In OGSA, the capability concerned with the storage, description, access, update, location, transfer and other management of data. For the record, there are just two terms left to define in the attached file. I think we need to define "data staging" because this is a term that many people in the industry at large are not familiar with. We probably also need a definition of "storage management" (or possibly just "storage"). Best wishes, Dave. _____ From: ogsa-wg-bounces(a)ogf.org [mailto:ogsa-wg-bounces@ogf.org] On Behalf Of guru prasad Sent: 20 July 2007 19:52 To: Subramaniam, Ravi; Donal K.

Express AuthN - Kerberos Forwarding Use Case
by Blair Dillaway 22 Jul '07

22 Jul '07

A brief description of the Kerberos forwarding use-case is provided below so we have it recorded. This use-case was identified by Chris and Bill in response to discussion about whether the Express AuthN profiles should include Kerberos mechanisms. They have reviewed the text below and confirmed it describes the use-case they are concerned about. Kerberos Token Forwarding Use Case This use case describes a desired operational mode supporting use of a deployed Kerberos authentication infrastructure for grid access control. The grid environment could be within a single organization, or span multiple organizations if cross-realm Kerberos trusts have been established. The requirement is to support resource access by a job (J) running on behalf of a user (U) based on authenticated user identity and attribute information conveyed in a Kerberos token. The user is assumed to only communicate directly with a scheduling service (S) (for example, a BES container service). S then determines a suitable computational host and communicates the information necessary to run the user's job on that host. It is assumed all the grid services are web services which communicate using SOAP-based protocols. To support this use case, U must be able to authenticate to S using Kerberos. S is then responsible for binding the Kerberos authentication information to U's job request. Note that U doesn't know which execution host will eventually run J, and therefore can not supply a Kerberos service ticket for the execution host. When S schedules J, it authenticates to the execution host based on its identity, and must securely communicates U's Kerberos authentication information as part of the job creating request. The execution host then uses U's Kerberos authentication information (user's account and group membership) to establish the job's security context. This could involve running the job under the user's account or obtaining new Kerberos service tickets on-behalf of the user for any required job resources. The security context provides the authenticated information that determines the job's rights to access local and/or remote resources. Regards, Blair Dillaway

Int. Grid Interoperability and Interoperation Workshop (IGIIW 2007): Deadline extended until July, 29
by Morris Riedel 21 Jul '07

21 Jul '07

FYI: A possibility to publish interoperability/interoperation work in the context of OGSA Due to several requests for an extension, the deadline is extended to July 29th, 2007. -------------------------------------------------------------------- CALL FOR PAPERS International Grid Interoperability and Interoperation Workshop 2007 (IGIIW 2007) Bangalore, India, December 10th - 13th (1 day), 2007 http://omii-europe.org/OMII-Europe/igiiw2007.html to be held in conjunction with 3rd IEEE - Int. Conference on e-Science and Grid Computing 2007 Bangalore, India, December 10th -- 13th, 2007 http://www.escience2007.org -------------------------------------------------------------------- SCOPE The workshop will discuss the interoperability and interoperation aspects of current Grid and Web technologies, production Grid infrastructures in general, and the interoperability through emerging open standards in particular. In the context of this workshop, the difference between interoperability and interoperation is as follows: Interoperation is specifically defined as what needs to be done to get production Grid infrastructures (e.g. DEISA, EGEE, TeraGrid, OSG) to work together as a fast short-term achievement using as much existing technologies as available today. Hence, this is not the perfect solution and different than interoperability that is defined as the native ability of Grids and Grid middleware (UNICORE, gLite, Globus Toolkit) to interact directly via well defined interfaces and common open standards. This will enable cross-Grid use cases and applications from a growing range of domains in industry and science. The goal of this workshop is to bring together researchers and practitioners working in the area of interoperability and interoperation within Grid infrastructures and distributed environments, to exchange and share their experiences, new ideas, and latest research results as well as open problems. Enough time for intensive discussions will be provided and outcomes of the workshop will be summarized in the session. TOPICS OF INTEREST Topics of interest for the workshop include, but are not limited to: * Cross-Grid scientific and business applications * Grid system components that enable interoperability/interoperation * Boundaries and open problems related to interoperability/interoperation * Scientific/business scenarios for Grid interoperability/interoperation * Cross-Grid brokering and workflows, semantics and languages * Security challenges/solutions for Grid interoperability/interoperation * Management & monitoring of interoperable/interoperating Grids * Visualizations for applications of more than one Grid environment * Grid middleware interoperability/interoperation * Roadmaps of Grid technologies for interoperability/interoperation * Performance evaluation of interoperable/interoperating Grid components * Reliability & fault-tolerance during interoperability/interoperation * Autonomic behavior in Grid interoperability/interoperation PROCEEDINGS Accepted papers will be published in the conference proceedings. More information can be found at http://www.escience2007.org/Papersubmission.htm PAPER SUBMISSIONS Authors are invited to submit manuscripts reporting original, unpublished research and recent developments in the topics related to the workshop. Submitted papers should be not more than 8 pages, including figures and references, of double column text using single-spaced, 10-point font size on 8.5 x 11 inch pages, as per IEEE 8.5 x 11 manuscript guidelines which can be found at ftp://pubftp.computer.org/press/outgoing/proceedings/. Papers should be submitted electronically in PDF format as an e-mail attachment to igiiw(a)fz-juelich.de. All papers will be peer reviewed and comments will be provided to the authors.
