v1.0 · in consultationMetamodel documentation
The formal vocabulary of Public Framework: the elements, attributes and relationships we use to describe public administration. The documentation follows Public Framework Modelling Language 1.0 and covers all 12 layers.
Version 1.0 of the specification is in public consultation. Elements and relationships may be adjusted in response to the feedback received.
Foundations
Introduction to Public Framework Modelling Language

Principles and core concepts
The principles behind Public Framework Modelling Language 1.0 and the core concepts every model works with: the model, the element, layer and family, the relationship, the property, sheets and identity.
The layered framework
