Jeremy Zawodny said some interesting things about the GData Protocol. One significant aspect of this "child of Atom" is Google data namespaces (also referred to as "kinds"). What I wonder about is how this will dovetail with GBase's lightweight ontologies.

The work done to organize GBase useage around "item types" (not to mention the enormous amount of knowledge domain work that has been put into their search engine) enables Google to understand and answer the data needs of a multitude of knowledge domains. Google is getting into a feedback loop with users, and the result will be standard naming conventions for object types and fields.

Peter Van Dijck sees Google data namespaces as part of an emerging Google OS.
