Examples of Query

Last modified 18:30 ET November 26, 2007

Assumptions:

- Jazz is running at http://example.com
- client has already been authenticated as a user named Zoe
- existing project /jazz/projects/main
- zoe is authorized to work in project main
- no extant resources
- indexing rule for XML namespace http://music.example.com/schema

Each step shows 1 round trip from client to server.

==========================================

STEP 

The client POSTS a query to the database.

declare namespace rdf = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
declare namespace wi = "http://www.jazz.net/xmlns/workitems/";
for $index in collection("JRS_RDF_INDEX")/rdf:Description
  where $index/wi:workItemType = "defect" and 
        $index/wi:internalPriority = 1 and 
        $index/wi:internalState != 4
  return $index/fn:string(@rdf:about);

Date: [t592]
Content-Length: [nnn]
Content-Type: application/atom+xml
