Public Layer Lab

About

Public Layer Lab is a small independent public-interest research lab focused on digital and administrative arrangements that shape public and civic life.

Its work concerns arrangements in public institutions, civic infrastructures, and socially relevant organisations: the forms, registers, identity and eligibility systems, participation platforms, administrative processes, data flows, technical infrastructures, and other systems through which public responsibilities are carried out and people and organisations encounter institutions.

More public and civic life now passes through digital interfaces, standards, institutional hand-offs, data systems, and automated or semi-automated processes. These arrangements are rarely only technical. They combine law, policy, design, administration, data, infrastructure, organisational routines, and public expectations.

That matters because they can shape what becomes visible, what counts as valid evidence or participation, how people and organisations are classified, where responsibility and practical control sit, and how errors, exclusions, or institutional dependencies can be understood and addressed.

The phrase “public layer” refers to this meeting point between people, institutions, rules, organisations, data flows, and technical systems: the layer through which arrangements of public or social importance become visible, usable, understandable, contestable, or difficult to change.

Statutory frame

Public Layer Lab is the public-facing name used by Stichting Instituut voor Digitale Publieke Systemen. The stichting’s statutory purpose gives the work a wider frame than public administration alone: it concerns digital and administrative systems of public or socially relevant institutions.

Four values organise that frame.

Fair means paying attention to whether categories, burdens, evidence requirements, access routes, and outcomes are distributed justly and without unnecessary exclusion.

Accessible means looking beyond formal availability to whether people, communities, and organisations can actually use a system, route, or process in practice.

Understandable means that people should be able to grasp what is happening, what is expected of them, why a decision or classification matters, and where to find explanation.

Publicly accountable means that responsibility, review, correction, and justification should not disappear behind interfaces, workflows, data exchanges, organisational arrangements, or automated tools.

Across the research, concepts such as recognition, access, intelligibility, contestability, burden, repair, responsibility, institutional reliance, and practical control provide different ways of examining these commitments in concrete arrangements.

How the work helps

Public Layer Lab investigates and reconstructs how consequential arrangements work across institutional, organisational, and technical boundaries. The aim is to make important choices, dependencies, responsibilities, and uncertainties easier to see.

The work may take the form of source-grounded analysis, public explanation, research or methods notes, and exploratory materials developed through concrete questions and cases.

Public Layer Lab does not build or certify the systems it examines, and it does not replace legal, technical, policy, accessibility, security, procurement, or other specialist assessment. Its contribution is to clarify the underlying institutional questions and identify where more specialised examination is required.

How the work is developing

The research draws on political theory, law and policy, science and technology studies, public administration, civic technology, civil-society practice, and design-oriented analysis. This combination matters because the arrangements being studied are usually legal, technical, organisational, and political at the same time.

AI-assisted administration is one part of this wider field. Public Layer Lab examines it where automated or semi-automated processes affect public input, recognition, eligibility, representation, explanation, review, accountability, or practical possibilities for challenge and correction.

One developing analytical approach is Legitimacy by Design, which examines whether public-facing or socially relevant systems structurally support claims such as fairness, accessibility, accountability, intelligibility, recognition, participation, and contestability. It is one part of the developing research, not the organising framework for Public Layer Lab as a whole.

Who this may be useful for

The work may be useful to people who need to understand or ask critical questions about consequential digital or administrative arrangements — including those who design, commission, govern, scrutinise, fund, research, use, or are affected by them.

It is also intended for readers looking for clearer ways to describe how institutional and technical arrangements shape authority, access, recognition, decisions, public understanding, accountability, civic agency, and possibilities for correction or change.

Who is behind it

Public Layer Lab is currently being developed by Mimis Petridis under Stichting Instituut voor Digitale Publieke Systemen.

The public notes and working materials on this site form part of that development. They offer explanations, analyses, and developing approaches to questions that recur across systems of public or social importance.

Institutional base

Stichting Instituut voor Digitale Publieke Systemen is a Dutch stichting based in the Netherlands. It provides an institutional home for public-interest research, public explanation, and related analytical work on digital and administrative systems of public or social importance. For legal and registration details, see the Stichting page.

Public Layer Lab is in an early institutional phase. The site should be read as the public home of developing work, not as a claim that all worklines are already mature, funded, staffed, or externally validated.
