API's:

Layering (Proposal)

dojo.data           

• core data Read,Write,Identity
• common stores: JSONStore, XMLStore (only if common path notation possible)
  
• common programmatic data binding api (generic widget Trigger, Action, Binding), dojo.data.bind(...)
  

dojox.data          

• datastore implementations based on web standards (CSV, OPML, RDF, ATOM, YahooStore?, DeliciousStore?, etc.)
  
• If XML notation cannot be made common with JS, XML-specific programmatic databinding could go here or dojox.data.xml
• programmatic data binding api's for complex dojo core and dojox chart widget bindings (Tree, Table, Combobox, Chart)
  • alternative: Put widget-specific binders in dojox.data.dijit?
    

dojox.data.decl

• declarative data binding api (Wrappers for Declarative use cases Data, Action, ServiceAction?, including complex core widgets etc.)
