13、ernational Organization for Standardization) 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 establ

14、ished by the respective organization 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

15、field of information technology, 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. Dr

16、aft International Standards adopted 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 thi

17、s document may be the subject of 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 tech

18、niques. ISO/IEC 24791 consists of 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 2

19、4791-2:2011 ISO/IEC 24791-2:2011(E) 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, intermediat

20、e software systems, and applications 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 capa

21、bilities of automatic identification 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 technologie

22、s. This is the goal of ISO/IEC 24791.

23、t 1 Scope This part of ISO/IEC 24791 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 interfac

24、e(s) defined by this part of ISO/IEC 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 ab

25、stract definition of commands and operations 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 po

26、sition in the SSI architecture defined 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

27、extensions to further support operation 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/IE

28、C 24791, which defines the required interpretation and extension of ALE to fully support the SSI architecture and its interaction with ISO/IEC 15962 and ISO/IEC 18000.

The basic relati

36、onship among the interfaces and implementations 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

37、client to communicate with a service-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

38、 capabilities provided by the Services 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 a

39、nd implementations in the SSI, Unified 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 c

40、an be defined. UML is a very rich language, 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 t

41、he functions and the interfaces provided 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 24791-2:2011

42、ISO/IEC 24791-2:2011(E) 4 ISO/IEC 2011 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

43、 provides operations on tag and sensor 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 serv

44、ices to one or more Data Management Client 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

45、of RFID tag information from a Services 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 Ser

46、vices Endpoints. The Services Endpoint, 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 proc

47、ess of collecting and preparing tag data 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 o

48、perations. When requested by a Client, 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 architectu

49、ral requirement for the control functionality 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
