An OData representation of a grid-like result spanned by multiple axes could be achieved by a new transformation nest() that allows to embed data of grid cells as a nested collection of entities representing grid rows.  Relevant excerpt from section 3 in the referenced document: The nest transformation has two parameters. The first takes the name of a dynamic containment navigation property, the second is a (chain of) $apply transformations. nest( cnp, t ) applies transformation chain t to the input set and creates a result set containing a single entity that only contains the navigation property cnp , which in turn holds the result collection of t applied to the input set: { <cnp>: [ <result of t applied to input set> ] }
