Proposal:
This new feature is motivated by a concrete use case. The current version of the Data Aggregation specification already includes an example for a cross-table and describes how to retrieve its data using transformation groupby in combination with rollup. However, this data is returned as linear collection of entities. For working with data in a grid efficiently, it must be possible to access selected sections of the grid. Details are described in the document “Grid-Like Access to Aggregated Data”, sections 2 and 3: https://www.oasis-open.org/committees/document.php?document_id=62593&wg_abbrev=odata

Relevant excerpt from section 3 in the referenced document: The transpose transformation has two parameters. The first takes the name of a dynamic containment navigation property, the second is a (chain of) $apply transformations. transpose( 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: {color:#000000} {color} {color:#000000}[ \{ <cnp>: [ <result of t applied to input set> ] } ]{color} |
