Abstract: A method for validating the validity of a group member of a virtual resource is provided. A method for validating the validity of a group according to an embodiment of the present invention obtains parent resource type information of a resource designated by a group member ID included in a group generation request and validates the validity of the group by using the obtained parent resource information. Accordingly, the validity of a virtual resource as a group member can be validated.

Abstract: There is provided a data interworking method between a oneM2M system and an NGSI-LD system. The data interworking method according to an embodiment of the present disclosure includes: retrieving, by an IPE, resources in the oneM2M system that perform data interworking with the NGSI-LD system; retrieving labels of the retrieved resources; acquiring a mapping-rule from the retrieved labels; and storing the acquired mapping-rule. Accordingly, data interworking between data platforms using different standards is performed more easily, so that technology may go one step further to the goal of interconnecting and servicing all things in a global environment as IoT ultimately pursues.

Abstract: A method for managing semantic information on an M2M/IoT platform is provided. The method for managing semantic information according to an embodiment of the present invention stores semantic data in the first attribute of an M2M resource and updates a part of the semantic data stored in the first attribute. Accordingly, efficient management of semantic information on an M2M/IoT platform is possible, and particularly a partial update of the semantic information can be performed.
