Hi,
libgdata is a glib-based library for accessing Google online services.
I'm sponsoring this case for Jerry Tan from the Solaris Desktop group.
The timeout is set to March 24.
Thanks.
Jeff

2. Project Summary
2.1 Project Description:
Libgdata is a GLib-based library for accessing Google online services
using GData protocol which is provided by Google.
4. Technical Description:
4.1. Details:
Google provides GData as a simple standard protocol for reading and
writing data to access the services provided by Google, including
blogger, calender, contacts, documents, youtube, etc.
The GData protocol provides the following features for interacting
with the Google server: issuing HTTP requests, parsing XML-based
responses to queries, inserting a new entry, searching for a string,
update on a query, etc.
Examples:
To retrieve all public calendars for a given user, send "get" command
to port 80 of www.google.com server like this :
"GET /calendar/feeds/<calendar address>/public/full"
it will return a reply like
"<?xml version='1.0' encoding='UTF-8'?>
<feed xmlns='http://www.w3.org/2005/Atom'....>
<id>....</id>
<title>...</title>
....
<entry>
<id>...</id>
...
</entry>
</feed>"
To insert a new entry, send a Post request, and supply the XML
representation of the new entry, like this :
"POST /calendar/feeds/defaults/<calendar address>/public/full"
<?xml version='1.0' encoding='utf-8'?>
<feed xmlns='http://www.w3.org/2005/Atom'
<entry ...>
<title>...</title>
<summary>...</summary>
....
</entry>
</feed>"
Upon success, the server will respond with an HTTP 201 message
that contains the calendar entry submitted.
Client applications will act on behalf of a user of a Google service.
The user provides his username and password to the Google Service,
then the service returns an authentication token. The user can then use
this token along with every subsequent request on behalf of that user.
The Google Data APIs support multiple authentication methods depending
on what kind of client you're writing. If your client is a standalone
single-user "installed" application (such as a desktop application),
then you should use the "ClientLogin"; if your client is a multi-user
web application client, then you should choose between "AuthSub" and
"OAuth".Please refer section 5[4] for more details.
There are several Google Data client libraries provided by Google,
including Java, JavaScript, .Net, PHP, Python, Object-C.
Libgdata is provided by the GNOME community as a glib-based C library
to access Google's service using GData protocol.
It is already used by the totem YouTube plugin, and evolution plans to
use libgdata to replace its own GData library.

4.11. Security Impact:
Applications that use libgdata will act as a http client,
open Google's server port 80 or port 443 to read/write data,
just like lynx.
For authentication issues, please refer to section 5.4.
4.12. Dependencies:
The following versions of the imported interfaces are required:
GLib2 2.12 or above
libsoup 2.26.1 or above
