RAML to CentraSite REST API Mappings
Overview
This section describes how the RAML objects and properties (as described in the RAML specification) are mapped in the CentraSite REST data model. It shows the relationships between the RAML root section, parameters, body fields, and their REST data model. It also lists the relationships between RAML resources, methods, reference documentation, and security schemes, and how these values are mapped in REST API.
Note:  
CentraSite supports RAML version 0.8.
The following tables list the correspondences (mappings) between the fields of a RESTful API and RAML document:
RAML Root Section Fields
The root section of the RAML definition describes the basic information of a RESTful API, such as its title, version, base URI, default media types, and common schema references.
