  Abstract

Two core objectives of smart city to provide sustainable services are 『Improvement of the quality of citizens’ life』 and 『Sustainable growth of the city』. For a sustainable and spreadable smart city services, it is necessary to build an intelligent city operation system with city data that collected from various urban infrastructures. Especially, a data sharing system such as collection, storage, processing, sharing and utilization of city data should be established. Global countries such as the U.S. and EU. are continuously expanding infrastructure for realizing data-based smart cities. In Korea, as a core technology for realizing a data-based smart city, a smart city data hub based on the international standard, Next Generation Service Interface-Linked Data(NGSI-LD), has been developing to utilize in various fields by collecting high-quality data from urban systems. The smart city data hub has to be verified for the compliance of technologies such as interface and data model in order to be successfully applied to demonstration cities. In this paper, the target and scope of test verification of data model based on NGSI-LD interface were defined and the validation test was performed using the developed test specification and equipment. Also, we presented how the test and verification process of data model in Data Hub System makes it improving technical perfection and completeness. Results of this study are expected to be used as basic data as well as the index of technical completeness when the test verification system of smart city data hub is established for demonstration cities.
