New technological paradigm enabling sovereign data sharing amidst data is eating the world

Reference Architecture Model(RAM)

Loosely coupled architecture
consists of 4 Layers and 4 Perspectives

セマンティクス
L4

Semantics Layer

Layer that resolves the issue of endpoint and meaning. Enables the exchange of metadata in an accessible form to achieve semantics interoperability.

アイデンティティ
L3

Identity layer

Layer that resolves the issue of authentication and authorization. Enables the exchange of credentials in a verifiable form to achieve the necessary level of authentication and authorization.

トランザクション
L2

Transaction Layer

Layer that resolves the issue of format, query, and protocol. Enables controlling of transferring process that is independent of the format of the data and of the request or method

データ
L1

Data Layer

Layer that resolves the issues of sovereignty, tampering, and quality related to data. Enables exercising data sovereignty and data handling that guarantees data integrity and quality.
