CARDDAV:addressbook-multiget, Re: [Ietf-carddav] More comments on draft-daboo-carddav-02

[Julian Reschke]

Hi,

here are two changes that I would propose for 
CARDDAV:addressbook-multiget 
(<http://tools.ietf.org/html/draft-daboo-carddav-02#section-8.7>):

1) Elevate C:addressbook-data from a pseudo property to a regular 
element of the request/response format,

2) Augment the request with information that allows conditional retrieval.

Example:

Request:

  <?xml version="1.0" encoding="utf-8" ?>
    <C:addressbook-multiget xmlns:D="DAV:"
                         xmlns:C="urn:ietf:params:xml:ns:carddav">
      <C:addressbook-data>
        </C:if-none-match>
        <C:prop name="VERSION"/>
        <C:prop name="UID"/>
        <C:prop name="NICKNAME"/>
        <C:prop name="EMAIL"/>
        <C:prop name="FN"/>
        </C:addressbook-data>
      <D:href if-none-match='"23ba4d-ff11fb"'
 >/home/bernard/addressbook/vcf102.vcf</D:href>
      <D:href>/home/bernard/addressbook/vcf1.vcf</D:href>
    </C:addressbook-multiget>

Response:

    HTTP/1.1 207 Multi-Status
    Date: Sat, 11 Nov 2006 09:32:12 GMT
    Content-Type: text/xml; charset="utf-8"
    Content-Length: xxxx

    <?xml version="1.0" encoding="utf-8" ?>
    <D:multistatus xmlns:D="DAV:"
                   xmlns:C="urn:ietf:params:xml:ns:carddav">
      <D:response>
        <D:href>/home/bernard/addressbook/vcf102.vcf</D:href>
        <D:status>HTTP/1.1 304 Not Modified</D:status>
      </D:response>
      <D:response>
        <D:href>/home/bernard/addressbook/vcf1.vcf</D:href>
        <D:status>HTTP/1.1 404 Resource not found</D:status>
      </D:response>
    </D:multistatus>

Best regards, Julian
