Demanding Business Drivers
• Multi-disciplinary collaborative configuration design of complex aerospace products
• Integration of the product design process chain (CAE/CAD/CAT) including external engineering companies, developers and suppliers
• Drug discovery environment managing the distribution of both public and commercial bioinformatics data and analysis services
• Virtual Global Information System Centre supporting the distribution and integration of large scale meteorology data providers

GRIA Overview (http://www.gria.org)
• Open source Grid middleware aimed at supporting B2B collaboration based on proven e-Commerce principles
• V4.3.0 has easy-to-use yet powerful functionality– business-to-business accounting and QoS services– distributed file transfer, storage and processing– OGSA-DAI database services – inter-domain distributed workflow using Taverna
• V5.0 to be released May 2006• Aligned with key Grid/web service standards and
specifications– WSRF Profile, WS-N, WS-Federation, WS-I Basic Profile and
WS-I Basic Security Profile

GRIA: Supporting the needs of business
• Develop Grid infrastructure to support cost effective dynamic business collaborations
• Some important business drivers that we need to support– minimal authorisation and administration– explicit trust decision points and value exchange– unite customers and suppliers based on SLA’s rather
than a community-based resource provision– higher-levels of management grounded in business
objectives – firewall and network friendly– compliance with industrial operational security policies
(ISO/IEC 17799:2005)

SIMDAT’s Industrial Grid Profile
• Whitepaper aimed at industrial Grid users from SIMDAT Grid technologists (Intel, NEC and IT Innovation)
• Motivated by business needs– Understand issues with key Grid-related
specifications when applied to industrial applications• security, operational, performance requirements
– Recommend how the specifications can be safely adopted
– Publish industrial Grid profiles to wider community– Engage with appropriate initiatives to influence future
direction of specifications • Currently under internal review, looking to publish Q3
2006 following proof of concept deployments

Some Key Specifications and Standards
• WS-Addressing (WS-A)– describes the encapsulation and use of a (possibly contextualised)
Web Service address via End Point References (EPR)• Web Service Resource Framework (WSRF)
– collection of specifications, which describes a particular use of WS-Addressing to access resources via contextualised Web Services
• WS-Notification (WSN) – collection of specifications, which builds further on WSRF to define
patterns for transmitting notifications between Web Services• OGSA WSRF profile
– defines normative functionality expected of an OGSA-compliant Grid, building on WSRF and WSN.
• Others under analysis include WSDM, WS-Agreement, WS-Trust, WS-Federation, JSDL, etc
