Sometimes you’re only interested in specific elements from a Google Data API feed. With most APIs, you typically have to retrieve the entire feed and parse out the individual required elements. This can be very expensive for some applications-- especially mobile apps with limited bandwidth.Google Calendar Data API . Partial response and update allows you to request and update feeds containing only the elements that you’re interested in.GET http://www.google.com/calendar/feeds/example@google.com/private/full?fields=entry(title,gd:when) Response:<?xml version="1.0" encoding="UTF-8"?> PATCH. The HTTP PATCH method prompts for the requested changes to be applied to the resource defined by the request URL. To remove elements, partial updates can use the gd:field attributes, which specifies elements to remove before merging with the target source. The example below updates the event title and time.PATCH http://www.google.com/calendar/feeds/default/private/full/eventID HTTP/1.1 As you can see, the ability to partially request and update feeds greatly reduces the amount of data transferred, which is especially important in the mobile world.Developer’s Guide .post on the Google Code Blog .Posted by Peng Ying, Google Calendar API Team

Hello! I've been trying to use partial update with the Calendar API, but keep getting 'invalid request uri' response.
The URI is use is the edit uri for an event I try to modify. I've posted a question about this in the Calendar API help forum. It would be great if an answer could be provided there :)
Thanks,
