Google today updated its collection of data APIs, adding source code for YouTube and Google Contacts, and further said the entire API set will properly compile in the iPhone SDK. The YouTube API allows any video-capable program to upload content to the service, with the accompanying tags and posting information. Similarily, the Google Contacts API allows users to embed Google Contacts functionality directly into applications that could make use of such information.
The addition of iPhone functionality to the APIs will open Google's services directly to iPhone SDK developers, allowing them to synchronize with Picasa, Blogger, and Youtube, among others. The source code for the Google Data APIs is available directly on the Google Code page.
