Cloud Standard

1. The name of the specification

SNIA Cloud Data Management Interface

2. A short statement (<100 words) of the purpose and function of the specification The SNIA Cloud Data Management Interface (CDMI) is the functional interface that applications will use to create, retrieve, update and delete data elements from the cloud. As part of this interface the client will be able to discover the capabilities of the cloud storage offering and use this interface to manage containers and the data that is placed in them. In addition, metadata can be set on containers and their contained data elements through this interface.

3. The version number (or other distinct identifier) and date of the most recently approved version of the specification.

SNIA Architecture - 1.0.2 standard ISO/IEC 17826 Information technology -- Cloud Data Management Interface (CDMI)

4. If the specification is part of a group of explicitly related specifications from the same source, the name of the group of specifications. Not applicable

5. URI for the normative text of the specification http://www.snia.org/tech_activities/standards/curr_standards/cdmi http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=60617

SOURCE

6. The name of the SDO that generated/authored/hosted the specification. Storage Networking Industry Association International Organization for Standards

7. URI for the SDO http://snia.org http://www.iso.org

8. The level of approval that the SDO has conferred on the specification as described by the SDO's process. SNIA Architecture (Final Standard) International Standard

9. The language or languages in which the specification is available. US English

SUBJECT

10. Which of the categories of Cloud services does the standard address? (Infrastructure as a Service - IaaS, Data Storage as a Service - DaaS, Platform as a Service - PaaS, Software as a Service - SaaS) DaaS (Cloud Storage)

11. Does the standard address both functional and management aspects of the service? Yes. Management is done by setting metadata on containers of data and individual data elements. The functional interface allows CRUD semantics for storage of data via HTTP.

OPTIONAL

14. URI for the SDO's posting location, (if any) for notices from participants or individuals regarding claims under the rules stated under number 15. SNIA IP Policy

15. Interoperability, conformance, or certification test activity for the specification (by owner name or URI).

None

16. Known implementations of the specification (by owner name or URI).

The SNIA Cloud Storage TWG has produced an open source reference implementation. A number of commercial vendors are shipping CDMI enabled offerings.
