Unified Algorithmic Process Format

UAPF is an open, machine-readable format that packages BPMN, DMN and CMMN models – plus metadata – into a single artifact that humans, engines and AI agents can understand and execute.

Quick start

Clone the reference repository and inspect an example UAPF package:

git clone https://github.com/UAPFormat/UAPF-Reference.git
cd UAPF-Reference/examples/basic-process
# inspect manifest.json, /models/bpmn, /models/dmn, /models/cmmn

UAPF is designed to integrate with existing BPMN/DMN/CMMN tools and workflow engines – no need to throw away your modeling stack.

Why a unified format?

Today, workflows, decision tables and case models are often stored in separate tools, with no single artifact representing “how this process really works”.

  • Scattered models.
    BPMN diagrams, DMN tables and CMMN models live in different silos, making execution and governance difficult.
  • Implicit contracts.
    Engines and integrations rely on conventions and ad-hoc glue rather than explicit, portable contracts.
  • AI without structure.
    AI agents need a clear, machine-readable description of workflows and rules – not just natural language.

What UAPF provides.

UAPF acts as a container and contract for algorithmated processes.

  • • A single package containing BPMN/DMN/CMMN models and their metadata.
  • • Stable identifiers for processes, tasks, decisions and events.
  • • Execution, versioning and governance metadata.
  • • A foundation for engines, AI agents and registries to interoperate.

Package structure at a glance.

A typical UAPF package is a directory (or ZIP) with a manifest and model folders: 

my-process.uapf/
  manifest.json
  models/
    bpmn/
      main.bpmn
      subprocess_*.bpmn
    dmn/
      decisions.dmn
    cmmn/
      case.cmmn
  tests/
    scenarios/*.json
  docs/
    overview.md

Community and governance.

UAPF is stewarded by practitioners who use BPMN/DMN/CMMN and AI agents in real projects. The long-term goal is an open governance model with working groups, formal releases and a registry of tools.

You can join the discussion, propose changes and contribute implementations via GitHub issues and discussions. Larger organizations can get involved through working groups and reference projects.
