is further made up of re-usable and modular Building Blocks arranged in various configurations as
per the needs of each use case.

The NUIS is envisioned as a shared digital infrastructure that fosters innovation and collaboration
in the ecosystem by unlocking the collective imagination to create novel solutions. The NUIS is
predicated on the empowerment of people and enablement of processes in the ecosystem to
drive solutions at scale and with speed.

The NUIS is a collection of cloud-based services. Each service efficiently provides a single capability
across multiple urban services, accessible through using simple, open APIs compatible with
global standards. In addition, it provides a set of open standards and specifications that enable
the ecosystem players to innovate on the stack. Together, these services and standards create a
powerful framework to drive convergence and a faster implementation cycle for any urban initiative.

The stack approach may facilitate the SSC by:

• Unbundling the challenge into micro problems such as need records of Identity & Verification.

• Arranging the micro problems into various layers based on how context-specific they are and
identifying micro solutions for each such as data infrastructure layer, core service layer, urban
solutions layer, and so on.

• Identifying the Building Blocks from the existing stack which can be leveraged such as Digital
Identity, Payment Registries, Geographic Information Systems (GIS), eSign, etc.

• Use of principles, specifications and standards.

Referring to point (3) above, it is important to mention that IndEA has certain common public
digital goods such as Aadhaar (Digital Identity; also read for “faceless” feature), Unified Payment
Interface (for Payment registry; also read for “cashless” feature), DigiLocker (for documents; also
read for “paperless”); and many more. These core digital goods will let NUIS customize its digital
services to citizens.

To understand more, please refer to Figure 51 and Figure 52 below, which explains the role of
Building Blocks. In Figure 51, the capabilities are rolled out with a specific roll-out of the programme.
For example, “Smart Governance” indicated in orange will lay out “Trade licence” in Solutions, “User
registry” in Core Data Infrastructure layer, and so on.

Figure 52 explicitly conveys how different Building Blocks have been used for each layer. Data
Specifications Infrastructure, Common Registry Infrastructure, Data Encryption and Signing
Infrastructure, Data Exchange Infrastructure are the key Building Blocks required in the Core Data
Infrastructure layer. Similarly, Authentication, Authorization, Billing (demand and receipt generation),
File management, Grievance management, Localization, Notifications, Reporting, Telemetry, Urban
GIS, User management, Workflow management are the key Building Blocks required in the Core
Services layer. Context/programme-specific components, priority-based Building Blocks are
developed in the Urban Solution Platform.
