1 Foreword

The following files are part of the Redfish development effort:

DSP0218 - Platform Level Data Model (PLDM) for Redfish Device Enablement Specification - Binary-encoded JSON (BEJ) and dictionary-based mapping of Redfish schemas and properties into PLDM messages.
DSP0266 - Redfish Specification - Main Redfish Specification.
DSP0268 - Redfish Data Model Specification - Normative descriptions and additional text for every schema defined in DSP8010 and example payloads for every resource.
DSP0270 - Redfish Host Interface Specification - "In-band" or "OS-based" Redfish host interface.
DSP0272 - Redfish Interoperability Profiles Specification - Structure and JSON document that is used to define and publish an interoperability profile that checks an implementation's conformance to a defined minimum set of functionality.
DSP2043 - Redfish Mockups Bundle - Set of mockups that can be used as sample output from GET responses from a Redfish service. Informative in nature, it was used to develop the schema. A person can set up an NGINX or similar server and configure it to output JSON format and then use this directory for demonstration purposes.
DSP2044 - Redfish White Paper - Non-normative document helping those new to Redfish understand how to interact with the Redfish service and understand common functions and tasks.
DSP2046 - Redfish Resource and Schema Guide - Informative documentation regarding common Redfish resource properties and a listing of properties that can be found in each of the Redfish resources.
DSP2053 - Redfish Property Guide - Informative documentation providing an index to individual property definitions across all Redfish schema.
DSP2065 - Redfish Message Registry Guide - Informative documentation providing details regarding the messages defined in Redfish standard message registries.
DSP8010 - Redfish Schema - Redfish schema definitions. These files are normative in nature and are normatively referenced by the Redfish Specification. The three schema formats are CSDL (OData Common Schema Definition Language format, which is in XML), JSON Schema, and OpenAPI schema. These schema definitions should be functionally equivalent, thus specifying the schema in three different languages.
DSP8011 - Redfish Standard Registries - Redfish registry definitions. This bundle of Redfish registries includes message registries used for Redfish-defined messages including events and privilege maps.
DSP8013 - Redfish Interoperability Profiles Bundle - Bundle of published Redfish interoperability profile documents and supporting schema and sample documents used for creating profiles.

2 Redfish Schema Bundle contents

This bundle contains the set of Redfish schema files. The contents of the folder are put into several folders. Each folder contains a complete set of Redfish schema files for a given schema language. The folders are:

Folder	Description
`csdl`	OData Common Schema Definition Language formatted as XML files. The `RedfishExtensions_v1.xml` and `Resource_v1.xml` files contain core definitions of Redfish.
`dictionaries`	Redfish Device Enablement (RDE) dictionaries formatted as Binary-encoded JSON (BEJ) files. The `annotation.bin` and `annotation.map` files contain core annotation definitions of Redfish.
`json-schema`	JSON Schema formatted as JSON files. The `redfish-schema..json` and `odata..json` files contain supplementary information about the schema files.
`openapi`	OpenAPI formatted as YAML files. The `openapi.yaml` file contains the OpenAPI service document that describes all of the standard paths.

In addition, the bundle includes several schema guide documents, generated from the contents of Redfish schema files and published separately by DMTF, as a convenience. These documents are updated for each Redfish schema bundle release.

File	Description
`DSP2046_<ver>.PDF`	Redfish Resource and Schema Guide - Informative document presenting the contents of the Redfish schema in an easily consumed table format. Organized by schema name, the document shows a listing of properties that can be found in each of the Redfish resources.
`DSP2053_<ver>.PDF`	Redfish Property Guide - Informative document providing an alphabetic index to individual properties defined across all Redfish schema.
`DSP0268_<ver>.PDF`	Redfish Data Model Specification - Normative document presenting the contents of the Redfish schema in an easily consumed table format. Similar to DSP2046, the document is organized by schema name, but populates its tables using the normative text and descriptions from the schema files.

Improved schema description text, updated RFC references, and white space consistency throughout.
(all Collections)	n/a	Corrected URI of the schema locations to the /schemas/v1 repository instead of the /schema location, which contains only the latest version of each schema. Corrected missing `anyOf` structure to allow `idRef` references to collections.
(all files)	various	Copies of all previously-released Redfish json-schema files have been created to follow the corrected json-schema filename format (v1_n_n instead of 1.n.n). The internal schema name references were updated to match this style, but otherwise the files are identical to their originally released content.
