1. A data interworking method comprising:
performing a first retrieval of retrieving, by an interworking proxy application entity (IPE), repositories in a first data platform system that perform data interworking with a second data platform system;
performing a second retrieval of retrieving, by the IPE, labels of the retrieved repositories;
acquiring, by the IPE, a mapping-rule from the retrieved labels;
storing, by the IPE, the acquired mapping-rule; and
performing a first interworking operation of interworking data of a repository of the second data platform system with data stored in a repository of the first data platform system, based on the stored mapping-rule,
wherein the first data platform system is a oneM2M (one machine-to-machine) system, and the second data platform system is an NGSI-LD (Next Generation Service Interface-linked Data) system, and
wherein the first interworking operation, performed by the NGSI-LD system, comprises:
subscribing, by the NGSI-LD system, to a resource of the oneM2M system;
receiving, by the NGSI-LD system, a notification regarding generation or refining of data of the resource; and
storing, by the NGSI-LD system, the notified data in an entity of the NGSI-LD system.
