Government Interoperability Framework (GIF)

What is Government Interoperability Framework (GIF)?

Based on the Digital Society Promotion Standards Guidelines, Digital Agency has provided a practical guidebook, "Government Interoperability Framework (Government Interoperability Framework)" (hereinafter referred to as "GIF"). By using GIF to improve data * 1, data coordination is ensured and interoperability between systems can be enhanced.
GIF is a data model model (reference model) to ensure data interoperability and to realize efficient information sharing and information linkage. GIF releases Implementation Data Model * 2, Core Data Model * 3, and Core Data Parts * 4.
A four layer structure consisting of a core data model including core data parts based on core vocabularies (concept dictionaries), an implementation data model consisting of four fields (administrative services, finance, disaster preparedness, and education), and data layers such as corporate BRs and evacuation shelter lists. Each layer is connected by upward arrows, showing the concept of developing standardized data from small parts.

* 1: What is data?
By preparing a consistent model from individual data items to the data model of the object, and creating data in accordance with it, we can prepare a system that can interoperate data that crosses organizations and fields.
* 2: What is an implementation data model?
A data model for specialized data sets, such as government or smart cities, that can be defined by combining and customizing core data models.
By configuring the implementation data model based on standardized models and parts, interoperability is not compromised, making this a model that can be used on site.
* 3: What is a core data model?
It is a data model that selects personal data sets that are commonly referenced in various situations as core data (individuals, corporations, contact information, addresses, facilities, etc.) and defines their basic data structure.
* 4: What is Core Data Parts?
GIF defines the value format (format) for data items such as date and address that appear in many data models and are commonly used. It is defined using the terminology of core vocabularies. It should be noted that core vocabularies form the foundation of the Common Lexical Infrastructure. They define vocabularies necessary for social activities such as names and addresses, and ensure interoperability with overseas vocabularies. Although it is released in IMI (Infrastructure for Multilayer Interoperability: Information Sharing Infrastructure), GIF users can ensure the interoperability of core vocabularies by referring to the core data model.
