Catalogue of Nastavia Voluntary Standards
Standard code	Standard name	Purpose	Documentation
NAVS.G1.21	Digital Systems Development Lifecycle (DSLC) Terminology and Semantic Foundations	Defines Digital Systems Lifecycle (DSLC) as a distinct and unambiguous term covering the complete lifecycle of a digital system, from the originating business need through retirement: Business Need → Scoping → Requirements → Realization Strategy → Design / Selection → Contracting → Delivery and Supervision → Acceptance → Operation → Evolution → Retirement	View standard
NAVS.G2.21	Compact Cash Denomination Code (CCDC) Operational Standard	Establishes a compact, fixed-length notation for operational identification of banknote and coin denominations. Its primary intended use is in bank cash-storage, treasury, branch cash-position, cash inventory, spreadsheet, reporting, and similar operational environments in which individual denominations are commonly represented as columns or other space-constrained identifiers and where full textual descriptions would make the information structure unnecessarily wide or difficult to scan.	View standard
NAVS.G4.11	Extended Universal Identification Number (x-UIN) Reference Models and Frameworks	establishes x-UIN, a reference framework for extending the safe, privacy-aware, interoperable, and user-controlled use of a persistent national UIN without requiring replacement of the underlying identifier.	View standard
NAVS.G4.21	Regulation-Aligned Artificial Intelligence (RAAI) Reference Models and Frameworks	Defines a technology-neutral four-layer reference architecture and a controlled coevolutionary feedback mechanism for AI systems that must continuously maintain alignment with regulatory, organizational, and operational requirements.

About the initiative

Standards that remain open to implementation

Nastavia Voluntary Standards are developed to address practical challenges emerging at the intersection of technology, governance, data, and institutional responsibility.

NAVS documents establish shared terminology, reference structures, principles, and implementation conventions. Unless expressly stated otherwise, they do not prescribe particular vendors, products, programming languages, infrastructure platforms, or deployment models.

The standards are offered for public use and continued discussion. Their voluntary nature is intended to encourage adoption, experimentation, interoperability, and gradual improvement across organizational and technological boundaries.
