Description

Method and system for publishing and discovering article traceability information in M2M system

Technical Field

The invention relates to the technical field of traceability, in particular to a method and a system for issuing and discovering article traceability information in an M2M system.

Background

Traceability is the ability to trace back an entity's history (e.g., operations, location) through record identification. The tracing is widely applied to monitoring the whole life cycle of the product. For example, food safety traceability can track food quality safety and related information in each link of food production, supply and marketing (including planting, breeding, production, circulation, sales, catering services and the like), so that the whole production and operation activities of food are always effectively monitored. Currently, the Global Traceability Standard (GTS) of GS1 has been released, and the field of application is full supply chain traceability, mainly focusing on the food and beverage industry. The GS1 standard supports efficient identification, collection, and sharing of products, locations, assets, and services.

Machine-to-Machine Communications (M2M) is a networked application and service with Machine intelligent interaction as a core, and realizes data communication without manual intervention by embedding a wireless or wired communication module and application processing logic in a Machine, so as to meet the informatization requirements of users on monitoring, command scheduling, data acquisition and measurement and the like.

oneM2M is a standard for M2M systems. The general goal of oneM2M standard organization is to create an open standard for the service layer of M2M communications to facilitate the establishment of a future network that integrates various devices and services, to make M2M services interoperable, and to make M2M applications possible to share underlying services and to implement independently of the network. Fig. 1 is a functional architecture diagram of oneM2M standard, which oneM2M standard includes the following functions:

application Entity (AE): the application entity is an entity in the application layer that implements the M2M application service logic. Each application service logic may reside in multiple M2M nodes and/or on a single M2M node multiple times. Each instance of execution of the application service logic is referred to as an "application entity" (AE) and is identified by a unique AE-ID. Examples of AEs include fleet tracking application instances, remote blood glucose monitoring application instances, power metering application instances, or control application instances;

common Service Entity (CSE): a common business entity represents an instantiation of a set of "common business functions" in an M2M environment;

underlying Network Service Entity (NSE): the network service entity provides the service from the underlying network to the CSE.

The configuration diagram supported by the oneM2M architecture in fig. 2 provides a possible configuration of interconnection between different entities, and specifically includes the following entities:

and (3) node: the node is an independently identifiable logical entity in the oneM2M system. The node may be a CSE-capable or non-CSE-capable node. The oneM2M architecture should include the following types of nodes.

1. Application Service Node (ASN, Application Service Node)

The ASN comprises a CSE and at least one AE as a node. There may be 0 or more ASNs in the oneM2M system, with the ASNs being capable of being in the M2M device.

2. Application specific Node (ADN, Application differentiated Node)

ADN contains at least one AE as a node, but no CSE. There may be 0 or more ADNs in oneM2M system, which can be in a restricted M2M device.

3. Intermediate node (MN)

The MN comprises one CSE and 0 or more AEs as one node. There may be 0 or more MNs in the oneM2M system, the MNs being able to be in the M2M gateway.

4. Platform node (IN)

An IN contains as a node one CSE and 0 or more AEs. There is one IN per oneM2M service provider. The CSE functionality contained IN the CSE IN the IN may not be applicable to other node types. IN can be IN the M2M service infrastructure.

5. non-oneM 2M node (NoDN)

The non-oneM 2M node does not contain oneM2M entities (not AEs and CSEs) as a node. Such nodes represent devices for interconnection/management with oneM2M system.

In the existing GS1 scheme, how to intelligently and interactively implement the tracing of the article in an M2M system composed of devices with networking and communication capabilities, such as an M2M terminal, platform middleware and the like, is not considered, while in the existing oneM2M standard scheme, the tracing application is not considered, and the tracing of the article cannot be implemented.

Detailed Description

The present invention will be described in further detail with reference to preferred embodiments and the accompanying drawings. It is to be understood that the following examples are illustrative only and are not intended to limit the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be understood that although the terms "first", "second", etc. are used hereinafter to describe various information, these information should not be limited to these terms, which are used only to distinguish one type of information from another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information, without departing from the scope of the present invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.

Example one

Fig. 3 is a flowchart illustrating a method for distributing the traceability information of the article IN the M2M system according to the first embodiment of the present invention, where the method of the first embodiment may be executed by the MN or the IN. As shown in fig. 3, the method for publishing the article traceability information in the M2M system in the first embodiment includes the following steps:

step S10, obtaining first creation request information sent by each initiator node in the M2M system, wherein the first creation request information comprises item data collected by the initiator node;

IN a first embodiment, the initiator node may be an ADN or an ASN, and after collecting the item data, the initiator node sends first creation (Create) request information to the MN or the IN. The first creation request information includes the item data collected by the node of the initiator, for example, the ADN is a temperature sensor, which collects temperature data of each planting stage of the product, and when the ADN sends the first creation request information to the MN, the first creation request information includes the temperature data collected by the temperature sensor.

Step S20, generating a target resource according to the first creation request information, where the target resource is used to store an item identifier and item data corresponding to the item identifier.

The item identification is an identification of the item monitored by the respective ADN or ASN, and the item identification may take various forms, such as 6924743915398, banana-201605031, hsdx.gz.farm.cniotroot.cn, and the like. The item identity for each item may be pre-stored IN the MN or IN, for example at the time of registration of the initiator node. The item identification may also be included in the first creation request information. The MN or IN generates a target resource according to the item data and the item identifier collected by the initiator node, namely, the item data and the item identifier are stored IN the form of the target resource.

Optionally, before generating the target resource according to the first creation request information, a step of verifying is further included. For example, the first creation request information further includes first verification information for verification. After receiving the first creation request message, the MN or the IN verifies the first verification message IN the first creation request message, and if the verification passes, performs step S20; if the verification fails, no processing is performed.

If the adopted first verification information is different, the MN or the IN also has different ways of verifying the first verification information, for example, if the first verification information is the identity information of the initiator node, it can be determined whether the initiator node has the authority to create the resource by verifying the identity information, thereby implementing verification of the first verification information. The first verification information may also be a designated resource name, and the verification of the first verification information is implemented by determining whether a resource corresponding to the designated resource name already exists IN the MN or IN. It should be understood that the above-mentioned manner of verifying the first verification information is an example, and should not be construed as limiting the present invention, and other verification manners may be used to verify the first verification information.

By the method for publishing the traceability information of the article IN the M2M system IN the first embodiment, the traceability information of the article can be published to MN or IN of the M2M system at the registration stage of each terminal node (such as ADN or ASN) or after registration under the oneM2M standard framework, and corresponding target resources are created, so that intelligent traceability of products can be facilitated, and monitoring of the whole life cycle of the products can be realized.

Further, the structure of the target resource is diversified, and in one embodiment, the target resource may include at least a first target resource for storing a mapping of the item identification attribute itemID and the item identification corresponding data attribute content. Referring to fig. 4, the process of generating the first target resource according to the first creation request information includes:

step S21, creating an item identification attribute itemID, and creating a data attribute content corresponding to the item identification according to the item data collected by each initiator node;

step S22, generating a first target resource according to the mapping between the item identification attribute itemID and the data attribute content corresponding to the item identification.

The item identification attribute itemID is used for storing an item identification list, and the item identification list contains one or more item identifications. The item identification correspondence data attribute content is used for storing item data corresponding to the item identification.

Optionally, the first target resource may further include a node access information attribute pointoacces, configured to store node access information of the initiator node, such as an IP address, an FQDN (Fully Qualified domain name), and the like. IN this way, the mapping between the item identifier attribute itemID, the data attribute content corresponding to the item identifier, and the node access information attribute pointoaccess is stored IN MN or IN, so as to obtain the first target resource as shown IN fig. 5. The first target resource structure shown in fig. 5 can create itemID and pointof access in the resources of the types < CSEBase >, < remoteCSE >, < AE >, < container >, < contentinstant >, but need not be created under all types of resources, and can be created under one or more types of resources.

Other attributes may also be included in the first target resource and will not be illustrated here. After the MN or IN generates the first target resource, response information may also be fed back to the initiator node, where the response information may include location information of the first target resource and/or location information of each attribute.

After the MN or the IN generates the first target resource according to the mapping between the item identification attribute itemID and the data attribute content corresponding to the item identification, second creation request information may be sent to another MN or IN, so that the tracing information may be published IN another MN or IN, as shown IN fig. 6, the publishing process includes the following steps:

step S23, sending second creation (Create) request information to the receiver node, where the second creation request information includes the item identifier list;

step S24, receiving first response information fed back by the receiver node after generating the second target resource according to the second creation request information.

The MN or IN sends second creation request information to the receiving node (namely other MNs or IN), wherein the second creation request information comprises an item identification list, and the item identification list comprises one or more item identifications. The item identification list may be obtained from an item identification attribute itemID stored by the MN or the IN itself. The receiving node creates an item identification attribute itemID according to the item identification list, and creates a node access information attribute pointofAccess according to node access information corresponding to the second creation request information, wherein the node access information corresponds to the second creation request information, namely corresponds to a party (namely a requesting party, which can be MN or IN) sending the second creation request information, the node access information can be an IP address or FQDN, and the node access information attribute pointofAccess is used for storing the node access information of the requesting party. The receiving node generates a second target resource according to the mapping between the item identifier attribute itemID and the node access information attribute pointoOfAccess, and the structure of the second target resource may also refer to the resource structure shown in FIG. 5. Other attributes may also be included in the second target resource, and are not described here.

In addition, optionally, after receiving the second creation request information and before generating the second target resource, the receiver node also verifies the second creation request information. For example, the second creation request information includes second verification information used for information verification, and after obtaining the second creation request information, the receiving node verifies the second verification information in the second creation request information, and the specific verification process may refer to the above description. After the verification is passed, the receiver node generates a second target resource.

After the second target resource is generated, the receiver node feeds back first response information to the requester, and the requester receives the first response information fed back by the receiver node, where the first response information may include location information of the second target resource and/or location information of each attribute.

Through the above process, the MN or the IN may issue the tracing information to other MNs or the IN.

Example two

The second embodiment of the present invention provides a method for issuing article traceability information IN an M2M system, where the method of the second embodiment may be executed by an MN or an IN. Compared with the first embodiment, the difference of the second embodiment is that the target resources are different, and the target resources in the second embodiment include a third target resource at least for storing the first item information attribute itemlnfo. Referring to fig. 7 and fig. 3 together, the method for distributing the traceability information of the article in the M2M system in the second embodiment includes the following steps:

step S210, acquiring first creation request information sent by each initiator node in the M2M system, wherein the first creation request information comprises item data and first verification information collected by the initiator node;

step S220, verifying the first verification information, and if the first verification information passes the verification, entering step S230;

step S230, creating a first item information attribute itemInfo according to the item identifier and item data corresponding to the item identifier;

step S240, generating a third target resource according to the first item information attribute itemlnfo.

Specifically, after acquiring the first creation request information sent by each initiator node (such as ASN or ADN) IN the M2M system, the MN or IN generates the third target resource according to the item identifier and the item data IN the first creation request information. The article identifier may be an identifier of an article monitored by each ADN or ASN, for example, a certain ADN is a temperature sensor a, which monitors the temperature of a tomato greenhouse, and the article identifier is an identifier of a tomato; another ADN is a temperature sensor B which monitors the temperature of the lettuce greenhouse, and the item identifier is the identifier of the lettuce. The item identifier may also be an identifier corresponding to an item formed after MN or IN processing, for example, if MN packages the above tomatoes and lettuce IN a mixed manner to form a mixed vegetable basket, the item identifier is an identifier corresponding to the mixed vegetable basket, and the item identifier may take various forms. The item identity for each item may be pre-stored IN the MN or IN, for example at the time of registration of the initiator node. The item identification may also be included in the first creation request information. And the MN or the IN generates a third target resource for storing the first item information attribute itemlnfo according to the item data collected by the initiator node and the item identifier. Optionally, before the information is requested according to the first creation, a step of verification is further included. For example, the first creation request information further includes first verification information for verification. After receiving the first creation request information, the MN or the IN verifies first verification information IN the first creation request information, and if the verification passes, executes step S230 to create a first item information attribute itemlnfo; if the verification fails, no processing is performed.

The first item information attribute itemlnfo is used to store a mapping between an item identification list and item data, where the item identification list includes one or more item identifications, and then a third target resource is generated according to the first item information attribute itemlnfo, such as the structure of the third target resource shown IN fig. 8, and MN or IN may create itemlnfo under a resource type < contentlnstance >. Other attributes may also be included in the third target resource and will not be illustrated here.

After the MN or IN generates the third target resource, response information may also be fed back to the initiator node, where the response information may include location information of the third target resource and/or location information of each attribute.

After the MN or the IN generates the third target resource according to the first item information attribute itemlnfo, third creation request information may be sent to another MN or IN, so that the tracing information may be published IN another MN or IN, as shown IN fig. 9, the publishing process includes the following steps:

step S250, sending a third creation request message to a receiving node (i.e. other MN or IN), where the third creation request message includes the item identifier list;

step S260, receiving second response information fed back by the receiver node after generating a fourth target resource according to the third creation request information.

The MN or the IN sends a third creation request message to the receiving node (i.e. other MN or IN), where the third creation request message includes an item identification list, and the item identification list includes one or more item identifications. The item identification list may be extracted from the first item information attribute itemlnfo stored by the MN or the IN itself. The third creation request information also includes third verification information for verifying information. After obtaining the third creation request message, the receiver node verifies the third verification message, and the specific verification process may refer to the above description. After the verification is passed, the receiving node creates a second item information attribute itemlnfo according to the mapping between the node access information corresponding to the third creation request information, that is, the party (that is, the requester, which may be MN or IN) that issued the third creation request information, and the item identification list, where the node access information may be the IP address or FQDN, etc. of the requester. The receiver node generates a fourth target resource according to the second item information attribute itemlnfo, and the structure of the fourth target resource may also refer to the resource structure shown in fig. 8. It should be noted that, in the second embodiment, both the first item information attribute and the second item information attribute are represented by itemlnfo to facilitate understanding, but the contents stored in the first item information attribute and the second item information attribute are different, the first item information attribute itemlnfo is used to store a mapping between an item identification list and item data, and the second item information attribute itemlnfo is used to store a mapping between node access information of a requester and an item identification list. Other attributes may also be stored in the fourth target resource, which are not illustrated here.

After the fourth target resource is generated, the receiver node feeds back second response information to the requester, and the requester receives the second response information fed back by the receiver node, where the second response information may include location information of the fourth target resource and/or location information of each attribute.

EXAMPLE III

Based on the method for issuing the article traceability information in the M2M system, the invention also provides a method for discovering the article traceability information in the M2M system. Fig. 10 is a flowchart illustrating the item tracing information discovery method IN the M2M system according to the third embodiment of the present invention, where the item tracing information discovery method IN the M2M system according to the third embodiment of the present invention may be executed by MN or IN. Referring to fig. 10, the method for discovering the article traceability information in the M2M system in the third embodiment includes the following steps:

step S310, acquiring first acquisition request information sent by an initiator node, wherein the first acquisition request information comprises a target article identifier;

step S320, according to the first acquisition request information, resource discovery is carried out, and after a target resource is obtained, item data corresponding to the target item identification are obtained from the target resource; the target resource is used for storing an item identifier and item data corresponding to the item identifier;

step S330, replying the item data corresponding to the target item identifier to the initiator node.

IN the third embodiment, the initiator node may be an IN-AE, or may be an ADN or an ASN. When the initiator node needs to discover the item tracing information, first obtaining (Retrieve) request information may be sent to the MN or the IN storing a target resource, where the target resource is used to store an item identifier and item data corresponding to the item identifier.

The first acquisition request information comprises a target article identifier, the target article identifier is an article identifier to be inquired, and the first acquisition request information is set according to the source tracing requirement of the user. Optionally, the first obtaining request information may further include resource discovery start position information, where the resource discovery start position information may be implemented by setting a parameter to, and according to an actual situation (depending on the position information of the target resource), the parameter to may be set to any one of < CSEBase >, < remoteCSE >, < AE >, < container > (or may be set to another resource, which is not illustrated here). After MN or IN obtains the first obtaining request information sent by the initiator node, resource discovery is carried out according to the resource discovery initial position information, if target resources are discovered, article data corresponding to the target article identification can be obtained from the target resources, and the article data is replied to the initiator node, so that discovery of article traceability information is realized.

Since the structure of the target resource is diversified, if the structure of the target resource is different, the parameters in the first acquisition request information are also different. In an optional implementation manner, referring to the first embodiment, the target resource includes at least a first target resource for storing a mapping between the item identification attribute itemID and the item identification corresponding data attribute content. The item identification attribute itemID is used for storing an item identification list, and the item identification list comprises one or more item identifications; the data attribute content corresponding to the item identifier is used for storing item data corresponding to each item identifier. At this time, the target item identifier in the first acquisition request information may be set by the parameter Filter criterion. Optionally, attribute in the parameter filtercriterion is set to "itemID ═ ID",' denotes wildcard, and ID denotes the target item identification, such as 6924743915398, banana-201605031, hsdx. The parameter content may also be set in the first acquisition request information, and the parameter content is set as the data attribute "content" corresponding to the item identifier. Meanwhile, other condition settings can be made through the parameter Filter criterion, for example, when there is a time requirement for the found item data, condition parameters such as "createdbyore", "createddafter", "modihedSince" and the like can be set. After receiving the first acquisition request message, if the first target resource is found, the MN or the IN may find the item data corresponding to the "ID" according to the mapping between the item identification attribute itemID stored IN the first target resource and the data attribute content corresponding to the item identification, and then reply the item data to the initiator node.

Still referring to the first embodiment, if the MN or the IN does not store the first target resource but stores the second target resource, referring to fig. 11, the process of discovering the article traceability information further includes:

step S410, second acquisition request information sent by an initiator node is acquired, wherein the second acquisition request information comprises a target article identifier and a node access information request instruction;

step S420, according to the second acquisition request information, performing resource discovery, and after acquiring a second target resource at least used for storing the mapping of the item identification attribute and the node access information attribute, acquiring node access information corresponding to the target item identification from the second target resource; the node access information attribute is used for storing node access information;

step S430, replying the node access information corresponding to the target item identifier to the initiator node.

The second target resource is at least used for storing the mapping of the item identification attribute itemID and the node access information attribute pointoOfAccess. Optionally, the target item identifier and the node access information request instruction in the second acquisition request information may be set by a parameter content and a parameter Filter criterion. Optionally, the parameter content is set to "itemID" (i.e. item identification attribute) and "pointoaccess" (i.e. node access information attribute), and the attribute in the parameter filtercriterion is set to "itemID ═ ID", where '×' represents wildcard, 'II)' represents the target item identification. In an optional implementation manner, the second obtaining request information further includes resource discovery start position information, where the resource discovery start position information may be implemented by setting a parameter to, and the parameter to may be set to any one of < CSEBase >, < remoteCSE >, < AE >, < container > (or may be set to other resources, which is not illustrated here).

After receiving the second acquisition request information, the MN or the IN performs resource discovery according to the resource discovery initial position information, and if a second target resource is discovered, the node access information corresponding to the "ID" can be determined according to the mapping between the item identification attribute itemID and the node access information attribute pointoaccess, and the node access information is replied to the initiator node. After the initiator node obtains the node access information, the corresponding node can be determined, and then the acquisition request information is sent to the node until the initiator node obtains the article data corresponding to the target article identifier, so that the discovery of the article traceability information is realized.

In another alternative implementation, referring to the second embodiment, the target resource includes a third target resource at least for storing the first item information attribute itemlnfo. The first item information attribute itemlnfo is used for storing the mapping between an item identification list and item data, wherein the item identification list comprises one or more item identifications. At this time, the target item identifier in the first acquisition request information may be set by the parameter Filter criterion. Optionally, the contentFilterQuery in the parameter filtercriterion is set to "ID", the ID represents the target item identifier, and the contentFilterSyntax in the parameter filtercriterion is set to "MATCH". The parameter content may also be set in the first acquisition request information, and set as "content" (i.e., item identification corresponding data attribute). After receiving the first acquisition request information, if a third target resource is found, the MN or the IN may find the item data corresponding to the "ID" according to the mapping between the item identification list stored IN the first item information attribute itemlnfo IN the third target resource and the item data, and then reply the item data to the initiator node, thereby realizing the discovery of the item tracing information.

Still referring to the second embodiment, if the MN or the IN does not store the third target resource but stores the fourth target resource, referring to fig. 12, the process of discovering the article traceability information further includes:

step S510, third acquisition request information sent by an initiator node is acquired, wherein the third acquisition request information comprises a target article identifier and an article information request instruction;

step S520, performing resource discovery according to the third acquisition request information, and after acquiring a fourth target resource at least used for storing the information attribute of the second item, acquiring node access information corresponding to the target item identifier from the fourth target resource;

step S530, replying the node access information corresponding to the target item identifier to the initiator node.

The fourth target resource is at least used for storing a second item information attribute itemlnfo. The second item information attribute itemlnfo is used for storing the mapping between an item identification list and node access information, wherein the item identification list comprises one or more item identifications. Optionally, the target item identifier and the item information request instruction in the third acquisition request information may be set by a parameter content and a parameter Filter criterion. If the parameter content is set to "itemlnfo" (namely, the second item information attribute), the contentFilterQuery in the parameter filtercritical is set to "ID", the ID represents the target item identifier, and the contentfiltersync in the parameter filtercritical is set to "MATCH". Optionally, the third obtaining request information may further include resource discovery start position information, where the resource discovery start position information may be implemented by setting a parameter to, and the parameter to may be set to any one of < CSEBase >, < remoteCSE >, < AE >, < container > according to an actual situation, or may be set to another resource, which is not illustrated herein. After receiving the third acquisition request information, the MN or the IN performs resource discovery according to the resource discovery initial position information, and if a fourth target resource is discovered, the MN or the IN may determine node access information corresponding to the "ID" according to the mapping between the item identification list stored IN the second item information attribute itemlnfo and the node access information, and reply the node access information to the initiator node. After the initiator node obtains the node access information, the corresponding node can be determined, and then the acquisition request information is sent to the node until the initiator node obtains the article data corresponding to the target article identifier, so that the discovery of the article traceability information is realized.

Example four

Based on the method for publishing the article traceability information in the M2M system, the invention also provides a method for subscribing the article traceability information in the M2M system.

The fourth creation request information includes attribute information of the subscribed target resource, address information of the receiver of the subscribed resource, setting information of the notification method of the subscribed resource, and fourth verification information (if verification is not required, the fourth creation request information may not include the fourth verification information). The target resource is located IN the MN or IN and is used for storing the item identifier and item data corresponding to the item identifier, and the attribute information IN the subscribed target resource represents the change of part (or all) of attributes IN the subscribed target resource.

The fourth verification information is diversified, and if the fourth verification information is different, the way IN which the MN or the IN verifies the fourth verification information is also different, and a part of the verification way has been described IN the first embodiment, and is not described again here.

In an optional implementation manner, two manners of sending the notification to the initiator node are provided, one is event-triggered notification, and the other is periodic notification, so that the setting information of the subscription resource notification manner also includes the setting information of the event-triggered notification manner or the setting information of the periodic notification manner.

Referring to the first and second embodiments, the structure of the target resource is diversified, and the attributes in the target resource are also diversified. The following describes an item tracing information subscription method in the M2M system in the fourth embodiment with reference to the structures of two target resources.

In an optional implementation manner, referring to the first embodiment, if the target resource further includes a second target resource for storing the mapping between the item identification attribute itemID and the node access information attribute pointoacces, and the initiator node needs to subscribe to changes between the itemID and the pointoacces. The following setting may be made in the fourth creation request information:

the attribute information in the subscribed target resource is set by the parameter eventNotificationCriteria: setting the condition attribute of the eventnotiationCriteria as "itemID" and "pointoOfAccess", and including other parameters as required; in addition, the parameter notification content type value may also be set to "modifiedattributes" indicating that only the modified attribute is notified.

The address information of the receiver of the subscription resource is set by a parameter notifiationuri: setting the parameter notifiationURI as the address of the receiver of the subscribed resource, such as: the address of IN-AE is "/CSE 0001/AE 0001".

According to the two conditions of event trigger notification and periodic notification, the following two setting modes can be respectively adopted for the setting information of the resource notification mode

(1) Setting information for event-triggered notification mode: the conditional eventType in the parameter eventNotification Criteria is set to "Update to attributes of the sub-to resource".

(2) Setting information of the periodic notification manner: a sub-resource < schedule > in which a period of notification transmission may be required is created under the < description > resource.

After receiving the fourth creation request information, the MN or the IN verifies the fourth verification information, and if the verification passes, other conditions IN the fourth creation request information are as follows: the attribute information in the subscribed target resource, the address information of the subscribed resource receiver and the setting information of the subscribed resource notification mode are used for creating the subscribed resource < description >, and a response message can be replied to the node of the initiator to indicate that the subscribed resource is successfully created.

In another optional implementation manner, if the target resource further includes a third target resource for storing a first item information attribute itemlnfo, where the first item information attribute itemlnfo is used to store a mapping between an item identification list and item data, and the initiator node needs to subscribe to a change of the itemlnfo. The following setting may be made in the fourth creation request information:

the attribute information in the subscribed target resource is set by the parameter eventNotificationCriteria: setting the condition attribute of the parameter eventnotiationCriteria as itemlfo and containing other parameters according to requirements; in addition, the value of the parameter notify contents type may also be set to "modified attributes", indicating that only the modified attributes are notified.

Then, similar to the previous embodiment, after receiving the fourth creation request message, the MN or the IN verifies the fourth verification message, and if the verification passes, the other conditions IN the fourth creation request message are: the attribute information in the subscribed target resource, the address information of the subscribed resource receiver and the setting information of the subscribed resource notification mode are used for creating the subscribed resource < description >, and a response message can be replied to the node of the initiator to indicate that the subscribed resource is successfully created.

In conclusion, the invention provides a method for publishing and discovering the article traceability information in the M2M system, solves the problem that the M2M system lacks a traceability solution, can realize article traceability automatically and intelligently under the oneM2M standard framework, and is beneficial to monitoring the whole life cycle of a product.
