2、 (XAMTM)SecretariatInformation Technology Industry CouncilApproved December 20, 2010American National Standards Institute, Inc.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 standa
3、rds developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that
4、 allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purc

23、nt is intended to be used by two broad 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 (eXten
24、sible Access Method). The second audience 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 subj
25、ect of the document and the aspects covered.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 SN
26、IA XAM and how XAM addresses the industry 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 ob
27、jects as well as the common data structures 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
28、 model of an XSet by describing applicable 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
29、XAM API.11, “Security” Describes three 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 For
30、mat”Describes the XSD (XML Schema Definition) for the XML manifest that is used by the XSet canonical format when importing and exporting an XSet.ii11 ScopeThis part of the XAM standard is a normative specification of the general architecture and semantics of the XAM API. It applies to programmers w
31、ho 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 of th
32、e 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-JAV

38、orm its intended operation. A fatal error indicates that the object instance on which the method was invoked has transitioned to the corrupt state.3.1.7 fieldA piece of uniquely identifiable data that can be attached to an XSet, an XSystem, or a XAM Library. Two types of fields exist: a property and
39、 an XStream.3.1.8 field attributeOne or more features associated with a field. A field has multiple attributes associated with it, including type (MIME type), binding (TRUE/FALSE), readonly (TRUE/FALSE), and length (length of the value).3.1.9 method An abstract interface definition for a specific pi
40、ece of functionality. When mapped to a specific programming language definition of the method, this may be a function, a procedure, a macro, or an object-oriented method.3.1.10 MIMEAcronym for Multipurpose Internet Mail Extensions. MIME types are used by XAM to indicate the format of the data contai
41、ned in an XStream. For additional information, see RFC2045 and RFC2046. INCITS 464.153.1.11 nonbinding fieldAn XSet field that does not affect the value assigned to the XUID when the XUID is created after committing the XSet to persistent storage.3.1.12 nonbinding modificationA modification that inc
42、ludes all field editing that is not a binding modification, specifically, adding or deleting nonbinding fields, changing nonbinding field values, changing the nonbinding field type, or opening a nonbinding XStream in writeonly or appendonly mode.3.1.13 non-fatal errorA method result indicating that
43、the invoked method did not perform its intended operation. A non-fatal error shall not cause an object instance to change its current state.3.1.14 OIDAcronym for object identifier.3.1.15 propertyA field whose MIME type attribute is one of the XAM-defined simple types (stypes).3.1.16 RBACAcronym for
44、Role Based Access Control.3.1.17 reference informationData that changes infrequently once written. Also commonly referred to as fixed content.3.1.18 Role Based Access ControlAn approach to controlling the system access of authorized users based on the users role within an organization.

See RFC4422.3.1.21 stypeA set of MIME types defined in the XAM specification that are used for field type attributes and are commonly referred to as simple types.3.1.22 synthetic fieldA XAM field that may not be physically represented within the XAM Storage System. Some fiel
47、ds may be derived from other state information within the XAM Storage System. From a XAM application perspective, it does not matter whether a specific XAM field is synthetic or not.3.1.23 system fieldA XAM field with a name attribute in the reserved system field namespace of .* (see Term 3.1.1, “ap
48、plication field”). XAM applications are prevented from creating fields in this portion of the field namespace, though they may be able to change a system field value at the discretion of the XAM Library and VIM implementations.INCITS 464.163.1.24 system propertiesA property that is created and manag
