Zend Gdata

Google Data APIs provide programmatic interface to some of Google's online services. Client applications submit queries and data via HTTP, and retrieve results. The Zend_Gdata component is a PHP 5 interface for accessing Google Data from PHP.

The PHP Recipe application is a small but complete example that demonstrates the five Google Base API services: queries, insertions, deletions, updates, and batch commands.

I was going to add AuthSub authentication for Ngeblog when people at Google Code team announced that Zend framework now has GData support.
After played around with it for hours, i finally got into a decision to use Zend Gdata for abstracting Ngeblog connection to Blogger. Unfortunately, Zend GData class library only supports AuthSub authentication, while Ngeblog already uses ClientLogin authentication and works fine so far.
So, to make it available for both type of authentication, i finally sat down and wrote some codes myself to add ClientLogin support for Zend GData. You can download the bundle in .zip here or in .tgz here which contains both original Zend_Gdata bundle and my Zend_Gdata_ClientLogin class for ClientLogin authentication.
