Recently, Google Data APIs have implemented new technologies in order to make applications and communications with Google Data APIs more efficient.  We'll present these new technologies, including ETags, Partial Get and Update, and a new compact JSON format, and show how you can use them to improve your applications.   We'll demonstrate these features by showing an example built on top of the Google Photos (Picasa Web Album) API.
