Minor nit in the problem definition:
"...simple set of mechanisms (the PROPFIND and GET methods) to locate
resources of interest, those meeting client-defined criteria."

I think this would be clearer if everything after the comma was deleted.

also in problem definition:

"capabilities of the modern storage systems."

I'm not sure what the queen's English would have to say about this sentence
but I suspect the "the" should be removed.

Other than these two nits I love the new charter! Very well written.
Congratulations are due to all.

>      Description of Working Group
> 
>         The goal of this working group is to provide searching
>         interoperability among the variety of underlying storage
>         systems whose data can be exposed by the WEBDAV extensions to
>         HTTP. The working group will define HTTP extensions that enable
>         server-executed queries to locate resources based upon their
>         property values and text content.
> 
>      Problem Definition
> 
>         WEBDAV and HTTP enable client-side searching by defining a
>         simple set of mechanisms (the PROPFIND and GET methods) to
>         locate resources of interest, those meeting client-defined
>         criteria. These mechanisms can be inefficient, do not
>         adequately deal with some simple content-based queries, and do
>         not take advantage of the advanced querying and caching
>         capabilities of the modern storage systems.
> 
>         The DASL Protocol will enable a HTTP/1.1 compliant scheme for
>         server-side searching to address these limitations. The working
>         group will define the following for a server-side searching
>         mechanism:
> 
>         - How to express the search: the syntax and semantics of a
>           query
>         - How to focus the query by identifying its scope

> 
>         A generalized search mechanism is a broad problem space. It

>         In-Scope items include:

>         - internationalized content
>         - text content matching

>         Out-of-scope items include:
>         - definitions of default property sets
>         - server-to-server communication protocols
>         - searching for non-text content (images, video, audio, etc.)

> 
>         (2) A protocol specification describing the additions to WEBDAV
>         (new methods, headers, request bodies, and response bodies)
>         needed to implement the DASL requirements. This will be a
>         Standards Track document.
