13、ardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organizat
14、ion to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology,
15、ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopt
16、ed by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of
17、patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24791-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. ISO/IEC 24791 consists of
18、 the following parts, under the general title Information technology Radio frequency identification (RFID) for item management Software system infrastructure: Part 1: Architecture Part 2: Data management Part 3: Device management Part 5: Device interface BS ISO/IEC 24791-2:2011ISO/IEC 24791-2:2011(E
19、) ISO/IEC 2011 All rights reserved vIntroduction Radio frequency identification (RFID) air interface technology is based on non-contact electro-magnetic communication among interrogators and tags. RFID software systems are composed of RFID interrogators, intermediate software systems, and applicatio
20、ns that provide control and coordination of air interface operation, tag information exchange, and health and performance management of system components. RFID technology is expected to increase effectiveness in many aspects of business by further advancing the capabilities of automatic identificati
21、on and data capture (AIDC). To achieve this goal through the successful adoption of RFID technology into real business environments, RFID devices, software systems, and business applications must provide secure and interoperable services, interfaces, and technologies. This is the goal of ISO/IEC 247
22、91.

23、1 defines the interface(s) that provide operations on RFID tag data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification within the Software System Infrastructure (SSI). Specifically, the interface(s) defined by this part of ISO/IE
24、C 24791 provide the following features: full support for the commands and responses for air protocols supported by this part of ISO/IEC 24791 at an abstraction level appropriate for Data Managements position in the SSI architecture defined in ISO/IEC 24791-1; an abstract definition of commands and o
25、perations that can be applied to different network bindings and encoding mechanisms; support for the encoding mechanisms defined in ISO/IEC 15962; volume reduction, format or structure modification, data analysis, and data access appropriate for Data Managements position in the SSI architecture defi
26、ned in ISO/IEC 24791-1; reporting of data to support application or data managing in formats controlled by the client, either inside or outside of SSI. This part of ISO/IEC 24791 is composed of the EPCglobal Application Level Events Standard, in its entirety, with extensions to further support opera
27、tion with ISO/IEC 15962 and the air protocols defined by ISO/IEC 18000. 2 Conformance Conformance for this part of ISO/IEC 24791 shall satisfy the conformance requirements of the EPCglobal ALE Standard and the requirements defined in Clause 9 of this part of ISO/IEC 24791, which defines the required
28、 interpretation and extension of ALE to fully support the SSI architecture and its interaction with ISO/IEC 15962 and ISO/IEC 18000.

The basic relationship among the interfaces and imple
36、mentations of the Software System Infrastructure is depicted in Figure 1. Figure 1 Architecture Overview including Relationships to other RFID Standards The Device Interface, Data Management, and Device Management each provide one or more interfaces that allow a client to communicate with a service-
37、providing implementation, either within the same computing device or across a network. These client and service implementations are consistently referred to as Client Endpoints and Services Endpoints, respectively, and in general, the Client Endpoint accesses the capabilities provided by the Service
38、s Endpoint. It is the responsibility of the specific standard to define the formats, procedures, operations, and conformance requirements of each interface. 7 UML Modelling Although Figure 1 provides a general overview of the relationship between the interfaces and implementations in the SSI, Unifie
39、d Modeling Language (UML) is used for the figures in this document to graphically represent the organization and operation of the Data Management interfaces and implementations so that a precise and common understanding of the relationships among the components can be defined. UML is a very rich lan
40、guage, but for simplicity only the Physical Diagram subset of the language is used to represent the architecture of the Software System Infrastructure. Physical diagrams, comprised of Component Diagrams and Deployment Diagrams, represent the relationships among the functions and the interfaces provi
41、ded by the SSI architectural elements as well as how these functions might exist in standards compliant solutions, respectively. Refer to ISO/EC 24791-1 for the normative description of the UML diagrams used in this part of ISO/IEC 24791. BS ISO/IEC 24791-2:2011ISO/IEC 24791-2:2011(E) 4 ISO/IEC 2011
42、 All rights reserved8 Data Management This clause describes Data Management in terms of the overall Software System Infrastructure described in ISO/IEC 24791-1. 8.1 Architecture As defined in ISO/IEC 24791-1, Data Management in the Software System Infrastructure provides operations on tag and sensor
43、 data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification. A Data Management component exposes an interface as represented in Figure 2 whereby a Data Management Services Endpoint provides services to one or more Data Management Cl
44、ient Endpoints over an interface binding. The Client and Services Endpoints may exist in a single device or may be accessed across a network. 24791-2 Data Management Services Endpoint Figure 2 Data Management Representation Data Management provides for transfer of RFID tag information from a Service
45、s Endpoint to a Client Endpoint that requested the specific operation or data. The request for services is considered to be part of the data function as defined in ISO/IEC 24791-1, and the request is communicated over the interface between the Client and the Services Endpoints. The Services Endpoint
46、, through a Data Management Implementation as shown in Figure 1, processes the Client requests, tag data, and possibly other external inputs (such as sensor, time or external logic signal) and delivers the results in the requested form to the Client. In the process of collecting and preparing tag da
47、ta for delivery to a Client, the Services Endpoint may group, filter, decode, and possibly augment the tag data with additional data. Data Management provides a control function that can be utilized by Clients to modify tag access parameters for requested data operations. When requested by a Client,
48、 the Data Management Implementation communicates the tag access parameters to the relevant interrogators using either the standard Device Interface or proprietary interrogator interface mechanisms, depending on the specific implementation. There is no architectural requirement for the control functi
49、onality to be communicated between Client and Services Endpoints through a single or different communication channel. The Data Management Interface supports the semantics of tag encoding information as defined in ISO/IEC 15962 including the concepts of the unique identifier, AFI, DSFID, as well as the actual data to be encoded. This interface also supports the semantics of the parameters specified in ISO/IEC 15962 that serve to further define the state of the tag after writi
