Property Names and WebDAV

Property Names and WebDAV

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

When you access item properties using the WebDAV protocol, the property names are represented as namespace-scoped XML elements complying with the Namespaces in XML Recommendation. For example, a property accessible through the Exchange OLE DB (ExOLEDB) provider with the name "DAV:contentclass" is represented through WebDAV as:

<a:contentclass xmlns:a="DAV:">[value]</a:contentclass>

The prefix "a" in this example acts only as a placeholder for the Uniform Resource Identifier (URI) "DAV:" and is not part of the property name.

The following is a typical response to a WebDAV PROPFIND Method request:

PROPFIND /path/resource.eml HTTP/1.1
Content-Type: text/xml
Content-Length: XXX

<?xml version="1.0" encoding="UTF-8"?>
<d:propfind xmlns:d="DAV:">
 <d:prop><d:displayname/></d:prop>
 <d:prop><d:getcontentlength/></d:prop>
 <d:prop><d:resourcetype/></d:prop>
 <d:prop><d:iscollection/></d:prop>
</d:propfind>

might look like the following:

<?xml version='1.0'?>
<a:multistatus
  xmlns:a="DAV:"
  xmlns:b="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/"
>
<a:response>
<a:href>http://example.com/path/resource.eml</a:href>
<a:propstat>
  <a:status>HTTP/1.1 OK</a:status>
  <a:prop>
    <a:displayname>resource.eml</a:displayname>
    <a:getcontentlength>367</a:getcontentlength>
    <a:resourcetype><a:collection/></a:resourcetype>
    <a:iscollection b:dt="boolean">0</a:iscollection>
  </a:prop>
</a:propstat>

In this example, displayname Field, getcontentlength Field, resourcetype Field, and iscollection Field were requested for the item at the URL "http://example.com/path/resource.eml". Note that the prefixes ("a" and "d") used as placeholders for the "DAV:" URI are different in the two XML strings. The following table shows full names and example-scoped XML elements side by side.

Note  The prefix used as a placeholder for the namespace URI is random and always refers to a namespace URI.
