Area Data Coordination Platform

Last Updated:

By linking and sharing data such as administrative procedures, health, transportation, disaster preparedness, and tourism data among various services that support daily life, we will provide services optimized for individual needs and promote regional digitalization. By utilizing data through area Data Coordination Platform, we aim to promote digital transformations in regions and realize a society where diverse happiness can be realized.

Area Data Coordination Platform

An area Data Coordination Platform is a system that aggregates regional (area) date and mediates it for various services such as administrative procedures, transportation, and tourism.
As the core of data-brokering function, we will utilize data-assets such as open data-for various services. In addition, we will promote efficient data-utilization by linking data-owned by each service among them. For this reason, we will demonstrate the true value of area Data Coordination Platform by connecting many services and data-assets.

When constructing and introducing an area Data Coordination Platform, it is important to avoid overlapping investments in similar data-linked function and to ensure open specifications that are not tied to specific services or operators. This will allow freedom in service design using an area Data Coordination Platform and will realize services optimized for individuals.
Based on this perspective, it is necessary to promote further utilization while expanding shared use of area Data Coordination Platform, in order to avoid unnecessary overlapping investment in infrastructure by each municipality and to realize sustainable operation.

Diagram illustrating overall configuration of data linkage system with focus on area Data Coordination Platform. To the left is the layout of residents and each service (administrative procedures, transportation, tourism, regional currency points, health, educational, environmental, disaster prevention, etc.), which is connected to the area Data Coordination Platform in the center by a bi-directional arrow as "Data linkage and utilization". The area Data Coordination Platform consists of 4 layers. At the top is the service management layer, which includes API gateway (highlighted in blue), user management, certification and authorization, service management, service usage history management, and developer portal. The second layer is the data management layer, which includes personal brokers (highlighted in blue) and non-personal brokers (highlighted in blue). The third layer is the asset management layer, which locates devices management and systems management. At the bottom is the external data linkage layer, which has a function for data processing and data transmission. At the bottom of the area Data Coordination Platform, external trust services are connected as "linkage" by bi-directional arrows. On the right are data assets (expanded as needed), including data holders (geographic data, open data, public data, etc.), other network infrastructure data (public service mesh, PMH, disaster prevention data, etc.), and sensor drones, which are connected to the area Data Coordination Platform in the center by an arrow for "data provision"

Data Model for Utilizing Area Data

In order to enable data interoperability and the migration of service applications for areas with high frequency of use in the region, we have released a data model that shows the concept of standardization and the units of organization for datasets that are distributed and shared in common.
