A Metadata Service Architecture Providing Trusted Data to Global Food Service

In food service, the transparency and reliability of product data are especially important requirements. But most of distributed information is non-trusted data without accurate source. To provide reliable data of food products, we propose the metadata service architecture for food service, applying GS1 Source defined by GS1 (Global Standard 1). GS1 Source is a standard for providing a communication of authentic and accurate product data between brand owners and consumers. We implemented the metadata service architecture as a java web service. The implemented architecture was applied in real food service and verified feasibility. We tested the performance of the web service by estimating request time, error rate, and response time, and conformed sufficient performance of the service. By applying GS1 Source to the food system, we can contribute to food service ecosystem with trusted data.
