Public Layer Lab

About

Public Layer Lab is a research-practice initiative on systems that shape public and civic life.

Its centre of gravity is digital and administrative systems in public institutions, social organisations, and civic infrastructures: the portals, forms, registers, identity checks, eligibility rules, participation platforms, cooperative governance tools, complaints routes, and AI-assisted processes through which people access services, are recognised, receive decisions, and seek explanation, challenge, or repair.

More public and civic life now passes through forms, portals, registers, standards, identity checks, eligibility rules, data flows, institutional hand-offs, 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 such systems do not only deliver services. They shape what becomes visible, what counts as valid evidence or participation, how people and organisations are classified, where responsibility is located, and how errors or exclusions can be corrected.

The phrase “public layer” refers to this meeting point between people, institutions, rules, data flows, and digital interfaces: the layer through which public and socially important systems become visible, usable, contestable, or difficult to challenge.

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, or automated tools.

The current analytical vocabulary of Public Layer Lab — recognition, access, intelligibility, contestability, burden, repair, responsibility, and practical control — is one way of examining those statutory commitments in concrete systems.

How the work helps

Public Layer Lab works by making design choices, institutional assumptions, burdens, and accountability gaps easier to see. The work may take the form of public explanation, source-grounded analysis, developing methods, or exploratory artifacts.

More explicitly, the work is meant to inform how systems of public or social importance are described, commissioned, designed, reviewed, and held accountable. Public Layer Lab does not build or certify those systems; it helps make the questions around them clearer so that legal, technical, policy, accessibility, security, and domain-specific review can be better directed.

How the work is developing

The work sits between research and practice. It 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 these systems 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 systems affect public input, recognition, eligibility, explanation, review, accountability, or repair.

One current methodological centre is Legitimacy by Design, a developing research-practice approach for examining whether public-facing or socially relevant systems structurally support claims of fairness, accessibility, accountability, intelligibility, recognition, participation, and contestability. It is not the full scope of Public Layer Lab, but it gives the work a concrete set of questions.

Who this may be useful for

This work is useful for people who need to ask critical questions about a public-facing or socially relevant system — including those who design, commission, govern, scrutinise, fund, use, or are affected by it.

It is also meant for readers who want clearer language for describing how systems shape access, recognition, decisions, explanation, accountability, and repair in public administration, civic infrastructure, and socially relevant organisations.

Who is behind it

Public Layer Lab is currently being developed by Mimis Petridis as a public-interest research-practice initiative under Stichting Instituut voor Digitale Publieke Systemen.

The public notes and working materials on this site are part of that development process. They offer explanations of concepts and distinctions that often matter in public and socially relevant systems: legitimacy, burden, contestability, transparency, interoperability, repair, responsibility, and practical control.

Institutional base

Public Layer Lab is the public-facing name used by Stichting Instituut voor Digitale Publieke Systemen, a Dutch stichting based in the Netherlands. The stichting provides an institutional home for public-interest research, public explanation, method development, and related 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.
