Alignment with NUIS Design Principles

This section outlines the key design principles defined in the National Urban Innovation Stack (NUIS) digital blueprint and describes how the design principles of IUDX align with them.

Interoperability through Open APIs and Open Standards

Through the principle of open APIs and open data models for data exchange, IUDX enables data interoperability across systems and domains. This interoperability supports the development of innovative applications that leverage diverse datasets made available through the data exchange.

Privacy and Security by Design

IUDX aligns with NUIS privacy and security principles through its consent-driven data sharing model, ensuring that data is accessed only by authorized entities. The secure-by-design approach reinforces this by adopting HTTPS-based APIs and implementing authentication, confidentiality, and integrity safeguards for all served data.

Ensuring Extensibility through Layered Design

The IUDX principles of extensibility, modularity, and service orientation contribute directly to layered design objectives. These principles ensure that components of the data exchange layer remain modular, independently scalable, and adaptable to evolving requirements. New features can be added with minimal impact on existing services.

Designing for Evolvability and Scale

The IUDX principles of scalable-by-design and service-oriented extensibility enable horizontal scaling of services as resource demands grow. Cloud deployability further ensures that scaling remains efficient and manageable in terms of cost and operations.

Federated Architecture

IUDX supports federated deployments through its scalable-by-design principle. The data access microservices can operate in a federated mode, allowing distributed and efficient handling of data across multiple servers.

Transparency and Accountability through Data

IUDX promotes transparency by providing open APIs and open data models that make public datasets easily accessible. With appropriate analytical tools, these datasets can support transparency initiatives and public oversight. The principle of accountability ensures that authenticated and authorized transactions are logged and auditable.

Inclusive and Domain Modeling

The principles of open APIs and open data models, combined with the minimalistic-by-design approach, ensure that IUDX remains inclusive and capable of supporting a diverse range of application developers. Domain-specific models can be incorporated easily through the extensibility of the data models.

Minimalistic Design

IUDX implements minimalistic API and data model design to remain domain-agnostic and easy to adopt. This aligns directly with the NUIS emphasis on simplifying interfaces while supporting a wide range of applications.

Unbundling

The IUDX principle of unbundling closely aligns with the NUIS objective of decomposing complex systems into smaller, independent microservices. This approach has guided the design of various IUDX APIs and supports efficient implementation and deployment.

Non-repudiable Transactions

The IUDX principle of accountability ensures that all stakeholder transactions are logged and can be audited, supporting non-repudiation and strengthening the integrity of platform operations.
