• Protocol Document: authors: Del Jensen, Saveen Reddy, Surendra Reddy; Alan Babich, Jim Davis; editor: Rick Henderson
• 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
