- VCDE WS
**May15, 2008**

## Background - Goals

**Goals: **
- Identify metadata queryable at the index service level
- Narrow focus for first revision ...
- Initial model defined to satisfy **discovery** use cases
- Support development of enhanced grid discovery client
- Resolve runtime services for terminologies of interest
- Additional metadata available through runtime services
- Allow/anticipate future expansion
