Google Adds Functionality to Container Documents
November 1, 2008
Chrome is here. Containers are all the rage even though users don’t know what these are. Google’s “controlling Communication within a Container Document” discloses interesting cross boundary functionality. Published by the USPTO on October 23, 2008, this invention by Michael Buerge and a handful of other Googlers says:
A system allows modules associated with different domains to communicate, such as within a container document. To transfer payload data from the first module associated with a first domain to a second module associated with a different domain, the first module adds the payload data as a text string to the URL of a transport module associated with the second domain. This way, the second module may directly access the modified transport module to obtain the payload data from its URL. The second module may likewise add other payload data as a text string to the URL of another transport module associated with the first domain, thereby enabling communication from the second domain to the first.
If a container sounds a bit like a virtual machine, I think you may be interpreting this prose in a similar way. Download US20080263566 here. I am opening this topic in my forthcoming Google and Publishing Monograph that will be available in December 2008 after Martin White’s and my new study Successful Enterprise Search Management from Galatea in the UK.
