VOs for the Arts and Humanities: A shopping list
Web 2.0 and the Grid
- ‘mashups’ - infrastructural diversity
- Interactive infrastructure
Formal methods for defining, storing and accessing (i.e. reusing) workflows
Project management
-Training
-Legal
-Reporting and documenting failure
Development and enrichment of the relationship between A&H and Computer Science
International coordination and collaboration
Dealing with computational, semantic and human heterogeneity

Supporting collective research –
virtual organizations
![Page 18: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/18.jpg)
Foster/Kesselman: Virtual Organisation scenarios
• Highly multidisciplinary simulation with several proprietary software components
• Thousands of researchers at hundreds of laboratories work together on the same design and pool their resources
• A large scale computer game with multiple interacting virtual worlds
Different number and types of participants, types of activities, scale of interaction and sharing of resources
Common: Mutually independent participants would like to work together and share what they have
VO: A set of institutions and/or individuals defined by resource sharing policies
![Page 19: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/19.jpg)
![Page 20: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/20.jpg)
• Sharing relationships can vary over time– Access rights– Resources involved– Participants
• Peer-to-peer• Different usage of the same resource, no a
priori definition• Implementation must be flexible and user
controlled in terms of varying policies, identities etc.
• Delegation of authority
Some initial challenges
![Page 21: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/21.jpg)
VOs in Grids
Ability to negotiate resource-sharing arrangements and then to use the resulting resource pool for some purpose. (Ian Foster)
![Page 22: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/22.jpg)
Grid: VO management
Before VOMS• Remember the way to
Athens • User is authorized as a
member of a single VO• All VO members have
same rights
VOMS• User can be in multiple
VOs– Aggregate rights
• VO can have groups– Different rights for
each– Nested groups
• VO has roles– Assigned to specific
purposes

Platform for A&H Computing Community
• Existing technologies:– Wiki– Blog– Content Management System (CMS)– Forum
• Existing problems:– Lack of resources– Security
Solution: Self-governing community using web2.0/Internet2 technologies
![Page 25: 4 6 2007 University of Illinois at Urbana Champaign](https://reader035.fdocuments.in/reader035/viewer/2022062405/5563527ed8b42a90698b56d8/html5/thumbnails/25.jpg)

Federation – Shibboleth
• Internet2 solution for attribute transport across organizations
• Distributed Identity Providers• Uses OpenSAML

What tools do VOs need?• Mailing List• Other open source tools :
– Wiki/Blog– File sharing (controlled R/W)– Role assignments
• Sharing identity across applications• Easy command line• Self-created applications• And maybe some integration with Grid
computational resources

VO’s – Not only HEI
• Final users will be members of a Virtual Organization– education– entertainment– cultural heritage management– cultural tourism
• ArchaeoGRID will offer resources otherwise difficult to access
