About Author.
Ott Sarv advises governments and delivery partners on Digital Public Infrastructure that remains lawful, accountable, and correctable when it meets real institutions and real decisions. The focus is governance that can be operated: mandates that can be defended, records that can be corrected, procedures that can be inspected, and systems that remain contestable under oversight.
Ott is the author of The Seven Layer Model for Digital Public Infrastructure: A Governance Architecture for Lawful Digital Public Authority. From here onward, this site refers to it as SLM.
This website exists to make governance legible and implementable. It is written for decision makers, architects, programme leaders, donors, and oversight bodies who need operational gates, not just guidance.
What I work on
Government advisory on Digital Public Infrastructure
Advises governments and delivery partners on governance-first Digital Public Infrastructure so public decisions remain lawful, accountable, and correctable at scale.
Policy drafting and policy architecture
Drafts policy instruments and policy architectures that translate public intent into enforceable rules, institutional responsibilities, and delivery constraints.
Legal framework drafting for digital public services
Drafts and reviews legal frameworks that define lawful effect, scope limits, institutional mandates, and remedy pathways for digital public services.
Programme design and supervision
Designs and supervises multi-institution programmes from concept to delivery governance, keeping mandates, custodianship, and change control aligned throughout implementation.
Digital Identity governance and wallet ecosystems
Shapes Digital Identity governance for issuers and relying parties, setting assurance expectations, evidence requirements, and remedy journeys that remain operable under dispute.
Data exchange governance and mandate-bound access
Defines mandate-bound access control for data exchange, ensuring disclosure is minimal, justified, evidenced, and reversible when decisions are contested.
Oversight, contestability, and remedy design
Designs contestation and remedy pathways that change outcomes, including evidence requirements, correction at source, and reversal of downstream effects.
Specifications, architectures, and conformance requirements
Drafts architectures and technical specifications that reflect governance decisions, including conformance requirements and evidence-grade logging for reviewability.
Training, briefings, and decision-support
Supports senior stakeholders with briefings and training that clarify governance roles, decision gates, and operational risks across DPI programmes.
