I strongly suggest you have a look at OData. The latest developments define a similarly lightweight JSON data format. It does everything this proposal does, and more (methinks the things this doesn't do will likely be added as time goes, simply reinventing the wheel - e.g. see the discussions above on pagination or rich query support).

To address your issues around defining a standard JSON API - OData is itself the standard API for any OData service. All that would differ between your OData service and mine is the schema and the data inside. How you explore that schema and access that data is what OData defines.
