2. SERVOGrid Grid Requirements
Seamless Access to Data repositories and large scale computers
Integration of multiple data sources including sensors, databases, file systems with analysis system
Including filtered OGSA-DAI
Rich meta-data generation and access with SERVOGrid specific Schema extending industry standards
Portals with component model for user interfaces and web control of all capabilities
Collaboration to support world-wide work
Basic Grid tools: workflow and notification

3. What should SERVOGrid do ?
Make use of Grid technologies and architecture from around the world
Coordinate with broad community through Global Grid Forum and OMII
Decide on domain specific standards SERVOGridML
Agree on particular approach within choices in international suite (use GT3 or not?, use portlets or not?, choose meta-data technology) and define SERVOGrid community practice
Develop software system infrastructure and applications specific to solid earth science
Worry about network interconnection between earthquake scientists and sensors

NASA Ames probably
Issues
Data formats/translation service for input and output data
Need list of software, databases
Security
Visualization

7. Discussion II Grid Software Components
Core Infrastructure – Apache Axis
Metadata Catalog/Registry e.g. Globus MDS but maybe can be done as now in Gateway (as implement for NASA JPL project)
Databases – Xindice MySQL plus OGSA-DAI
Workflow – Gateway
Job Submission – Gateway
Portlets for User Interface – Apache Jetspeed

8. Discussion III Process Activities
, shared internal web pages, external -- iSERVO
Desktop AV, Conferencing
Activities
Identify responsible people
Debug collaboration infrastructure
Tutorial from Marlon on current US Project
July 2003
Analyze test cases for hardware, software, data
Policy on machines/data access -- implications
