1. Retrieve Information from the API Hub

In this exercise, you will learn how to retrieve the information needed to consume OData based APIs from the Business Accelerator Hub.

How is the API of an OData Service specified

A Service Metadata Document describes the data model (i.e. structure and organization of all the resources) exposed as HTTP endpoints by the service. A Service Metadata Document describes its data in EDM terms using an XML language for describing models called the Conceptual Schema Definition Language (CSDL). CSDL is fully described in CSDL. When exposed by an OData service as a Service Metadata Document, the CSDL document is packed using the format described in EDMX.

The EDMX files for OData services delivered by SAP can be found on the Business Accelerator Hub (aka SAP API Hub).
