Requirements break-out session
-----------------------------------------------

NCH anounced goals for the session:

- List the requirements of each project
- Identify common requirements
- Prioritise requirements

We identified categories then went round the projects to identify project requirements:
Data Access (access to data sources - SQL queries, DB management, translation)
Data Integration
Application Support (client)
Performance/Reliability
Security
Usability/Support
Metadata/Registration


PD has a list of all participants in this discussion

For each category, we brainstormed some sub-points and each participant voted for those important to his/her project.
