SNIA Draft Technical Work available for Public Review

During the development of technical work, the SNIA may make available a Work-in-Progress DRAFT version for public review & feedback. Work-in-Progress DRAFTS are not endorsed by the SNIA for commercial shipping product implementation, but rather for review/feedback and prototyping work to ensure the work, when completed, will meet the needs of the Industry.
Work-in-Progress DRAFTS are subject to change. The Work-in-Progress DRAFT may be updated, replaced, or made obsolete at any time. Some of the Intellectual Property protections for users of SNIA software and specifications are not applicable to users of Work-in-Progress DRAFTs.

DRAFT CDMI Extensions and Profiles

The Cloud Storage Technical Work Group is adding new functionality to CDMI by publishing individual extensions the the CDMI standard. These can be implemented as needed in conjunction with a CDMI implementation to add new functionality before the next release of CDMI. As implementation experience is gained and interoperable implementations are tested, these extensions will be made part of the next release of CDMI.

The Cloud Storage TWG will also be publishing profiles of CDMI that scope it down to specific use cases based on different types of clouds.

See the dedicated web page DRAFT CDMI Extensions and Profiles for additional information.

CDMI Reference Implementation v1.0c DRAFT

The CDMI Reference Implementation is a SNIA Software development project that implements the Cloud Data Management Interface.

Self-contained Information Retention Format (SIRF) Use Cases and Functional Requirements v0.5a DRAFT

We propose an approach to digital content preservation that leverages the knowledge of the archival profession and helps archivists remain comfortable with the digital domain. One of the major needs to make this strategy possible is a digital equivalent to the physical container - the archival box or file folder - that defines a series, and that can be labeled with standard information in a defined format to allow retrieval when needed. The Self-contained Information Retention Format (SIRF) is defined to be that equivalent - a logical container for a set of (digital) preservation objects that also contains catalogs and metadata related to the entire contents of the container as well as to the individual objects. This logical container makes it easier and more efficient to provide many of the processes needed to address threats to digital content.

This document describes SIRF and the motivation for it along with its use cases and requirements. The use case model is used to derive the desired functional requirements of the SIRF format and the system that implements and uses it. The model uses graphical symbols and text to specify how users or applications in specific roles use SIRF. The document describes the use cases from a usage point of view: it doesn't describe how systems implement SIRF internally, nor does it describe SIRF internal structures or mechanisms.

Common Trace Semantics Specification v1.0 rev 11 DRAFT

The Common Trace Semantics Specification defines common, recommended semantics for data in I/O traces. Standardized I/O trace semantics will enable the development and use of common I/O trace collection and analysis tools as well as facilitate the sharing of the I/O traces themselves.

Cloud Storage Reference Model v0.3 Trial-Use Draft

This paper sets out a model of cloud storage elements that describes a logical view of their functions and capabilities using a descriptive taxonomy. The purpose of this model is to form a basis upon which industry efforts can be organized, needed standards identified and vendor products can be described by vendor independent terminology. In addition, this model is used to describe standard interfaces for cloud storage.
