For that “thing” to communicate, it should possess an

19、identifier of “which” it is. The ISO/IEC 15459- series does a good job identifying how groups that have been assigned an issuing agency code can create a character-based system of unique identification. There is no shortage of claimants to provide that identifier. Each is understandable due to its o

20、rigins and the perspective from which it comes. The Internet is a network and groups such as the International Telecommunications Union (ITU) and the Internet Engineering Task Force (IETF) view this identifier as a mechanism to facilitate network routing. ITU- T X.668 | ISO/IEC 9834-9 and ITU- T X.6

21、60 | ISO/IEC 9834- 1 attempt to fill this need from a network perspective. From a network perspective, it is accepted that the identification of an entity must resolve to an IP address for contacting it, whether its domain name “hangs” from an OID root using an OID resolver, or from a more general D

22、NS node (which may end up as the same thing). However, not everything is viewed from the perspective of the network, nor necessarily should it so be viewed. The network is a transport mechanism and the entities themselves have historic identifiers, which have their genesis from supply chain applicat

23、ions and identification. Ultimately, the various forms of unique identification identified within this International Standard need to be combined in a single message in an unambiguous form. This International Standard provides a method enabling this combination in an unambiguous form. ISO/IEC 2016 A

25、ructures. This International Standard specifies the common rules applicable for unique identification that are required to ensure full compatibility across different identities. The unique identification is a universal construct for any physical object, virtual object, or person. It is used in IoT i

26、nformation systems that need to track or otherwise refer to entities. It is intended for use with any IoT media. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

31、ndard, the term “thing” considers the following as synonyms; “item”, “object” and “entity”. A thing may be a person, object, or location; see also Annex D. When one considers the Internet of Things (IoT), the definition of the “thing” is most often coloured by the perspective of the person undertaki

32、ng the consideration. If one is coming from the world of sensors, the IoT is simply an expansion of a sensor network. If one is coming from the world of RFID, the IoT is simply an expansion of an RFID infrastructure. If one is coming from the world of geospatial data, the IoT is simply an expansion

33、of a location-based network. If one is coming from the world of telecommunications, the IoT is simply an expansion of a telecommunications network. In truth, all are correct. Figure 2 shows some of the possible iterations of “things” that would be possible to connect through the IoT, using various e

34、xisting communication interfaces. Of course, there are other possibilities and these iterations of IoT might actually be combined, e.g. a mobile phone reading a 2D symbol, an RF tag, or a wireless IC device.

35、 29161:2016ISO/IEC 29161:2016(E) A single transaction may need to capture several identities as it progresses from origin to destination (and return). For example, there may exist a need to capture, each time a transaction is recorded, the following: item identification; sensor identification; node

36、identification; gateway identification; target resource identification; location of data capture, if mobile; time of data capture; identification of the individual; As a virtual thing, software, or software content, ISO/IEC 8824-1:2015, 3.8.52 defines an “object” as A well-defined piece of informati

37、on, definition, or specification which requires a name in order to identify its use in an instance of communication. An object is an abstraction or simulation of physical things such as people (“people” are included in this definition of object only to be true to the quote, whereas this Internationa

38、l Standard discriminates between people, objects, and locations) and machines or intangible things such as events and processes that captures their characteristics and behaviour. Something you can do things to. An object has state, behaviour, and identity; the structure and behaviour of similar obje

39、cts are defined in their common class. 64 The following are properties that may characterize a thing: a) Identity: the property of an entity that distinguishes it from other entities; b) Type: describes the type of entity; c) Data: describes if and how persons, locations and/or other entities can be

40、 tied to the entity; d) Behaviour: describes the methods in the locations interface by which the location can be used. 5.2 Overview of the “IoT Network” The Internet of Things (IoT) network aims to enable almost everything to communicate with each other, being connected using various communication i

41、nterfaces and protocols like IPv4, IPv6, MAC addresses, CoAP/REST, XMPP, etc. Prerequisite for the IoT network is the possibility to tie various information to the right thing for a given purpose using unambiguous identities to which specified information is tied which is then exchanged using applic

42、ation defined protocols.

When an item is

43、removed, it is automatically sensed and information is sent so it is registered as being removed. The item will then be added as purchased and the price added to the room bill, to be paid at check out. Received information will also trigger refilling of minibar with the removed item. The scenario ab

44、ove requires that everything is possible to be uniquely identified, for which this International Standard is to provide a method for adding a wrapper to already existing identification schemes. 6 Unambiguous wrapper for unique identifiers in IoT applications 6.1 Overview Each form of unique identifi

45、cation stands on its own within the context of applications within that specific identifications domain. When one travels outside of that closed system, an open system form of the identification is required. The nature of the Internet of Things (IoT) is for people and objects to communicate with one

46、 and the other. This means that the unique identification scheme will need to accommodate established forms of identification. For the purposes of this International Standard, the “unambiguous wrapper” for identifiers used in IoT communications shall be a Uniform Resource Identifier (URI) defined by

47、 IETF, in RFC 3986. URIs are traditionally classified as either a Uniform Resource Locator (URL, using a string starting with “http:/”) denoting a web resource, or a Uniform Resource Name (URN, using a string starting with “urn:”) as defined in RFC 2141. In both cases, the URI is a text string from

48、a limited subset of US ASCII (for maximum portability across systems). The URI syntax is organized hierarchically, with components listed in order of decreasing significance from left to right. Other structures were considered, but the URI structure is widely accepted and extensively used with today

49、s AIDC data carriers, while providing the flexibility of a broader implementation. This International Standard is primarily concerned with supporting the interoperable use of Identification schemes from different domains, using existing URNs as needed to provide this interoperability in an efficient manner. Although URLs will also be used extensively in IoT applications, no special treatment of them is required for interoperability, and so this International Standard
