4、-,-,-Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement

5、has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American Na

6、tional Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institu

Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for in

27、 audiences. The first audience consists of application programmers who wish to use the XAM Application Programmers Interface (API) to create, access, manage, and query reference content through standardized methods that are collectively referred to as XAM (eXtensible Access Method). The second audie

28、nce consists of those who implement reference content stores that wish to provide access to their stores through the XAM standardized methods.OrganizationThe contents of this part of INCITS 464 are described as follows:Chapter Contents1, “Scope” Defines the subject of the document and the aspects co

29、vered.2, “References” Lists the referenced documents that are indispensable for the application of this document.3, “Terms and Conventions” Defines the terms and typographical conventions used in the document.4, “Business Overview” Gives the background of the SNIA XAM and how XAM addresses the indus

30、try and market needs.5, “Overview of the XAM Architecture”Gives an overview of the XAM architecture, including how the XAM Storage System vendors connect their storage systems through the XAM standard APIs.6, “XAM Objects and Common Operations”Defines the XAM objects as well as the common data struc

31、tures and operations that can be associated with the XAM object.7, “XAM Library and XSystems”Specifies the XAM applications logical view of the XAM Storage System and the software modules that comprise XAM.8, “XSet Operations” Defines the behavioral and semantic model of an XSet by describing applic

32、able methods on individual XSets and their elements.9, “XSet Management” Specifies XSet lifecycle management capabilities, including retention, deletion, and hold.10, “Query” Describes the query language grammar and the two levels of query supported through the XAM API.11, “Security” Describes three

33、 XAM security functions: XAM application authentication, XSystem authorization, and XSet access control.Annex A, “(normative) XAM Toolkit”Describes toolkit methods to simplify some common operations within XAM.Annex A, “(normative) Canonical XSet Interchange Format”Describes the XSD (XML Schema Defi

34、nition) for the XML manifest that is used by the XSet canonical format when importing and exporting an XSet.Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-iiCopyright American

It applies to programme

36、rs who are generating XAM applications in any programming language. It also applies to storage system vendors who are creating vendor interface modules (VIMs).This document uses an object model to describe syntax in examples; these examples are informative only. It is not a normative specification o

37、f the syntax of the XAM interfaces in any language binding. The normative specification of the syntax of the C language binding is defined in the XAM C API Specification XAM-C-API. The normative specification of the syntax of the Java language binding is defined in the XAM Java API Specification XAM

A fatal error indicates that the object instance on which the method was invoked has transitioned

Two types of fields exist: a property and an XStream.3.1.8 field attributeOne or more features associated with a field. A field has multiple attributes associated wit
