- Requirements: authors: Judith Slein, Saveen Reddy
Goal
- Searching interoperability:
- data exposed by DAV servers
- variety of underlying storage systems using DAV data model
- clarification: DAV-interoperable resources
Basic Problem
- WEBDAV mechanisms insufficient for common searching operations:
- PROPFIND & GET - client side search
- DASL - server side search
What protocol will say
- How to express search : syntax & semantics
- What is being searched: scope and resources
- What results look like
Why Server-Side Search?
- Less network usage
- Use server intelligence
- Ultimately: better performance
- No IETFish way to search website
Scope
- Wider is not better: A large problem space
- Focus on scenarios of interest to DAV
In Scope
- Typing of values
- Internationalized Content
- arbitrary XML values
- Access Control
- Text Content Searching
Out of Scope
- Default Property Sets
- Server-to-Server communication
- Non-Text content searches
- client control of server indexing
- must be http 1.1 compliant
