ecm-studio 0.3.3

Desktop-first Enterprise Capability Model studio with Git-managed JSONL storage.

ECM Studio

ECM Studio is a Windows-first desktop application for managing an Enterprise Capability Model as local, Git-managed JSONL files. It gives architects and capability owners a focused workspace for editing capability trees, reviewing change history, publishing model snapshots, and exporting portable artifacts without putting the authoritative model in a database.

Highlights

• Desktop UI built with React, Dockview, Fluent UI, and pywebview.
• Durable model storage in readable JSONL files under ecm/.
• Git-native workflow for checkpoints, scenarios, merges, restore, pull, and push.
• SQLite projection rebuilt locally for navigation and search speed.
• Capability map view with SVG and HTML export.
• Model import/export for JSONL, CSV, and bundled JSON.
• Release workflow for tagged ECM model exports and GitHub release publication.
• Light/dark theme support with native Windows chrome integration.

Install

ECM Studio requires Python 3.13 or newer. Install it from PyPI:

pip install ecm-studio

On Windows, if pip points at a different Python installation, use the Python launcher instead:

py -m pip install ecm-studio

With uv, install ECM Studio as a command-line tool:

uv tool install ecm-studio

Or install it into the current uv-managed environment:

uv pip install ecm-studio

Start the desktop app:

ecms

Open a workspace directly:

ecms C:\path\to\capability-model-repo

Check the installed package version:

ecms --version

Workspace Model

An ECM Studio workspace is a normal Git repository. The application stores the authoritative model in ecm/*.jsonl files and keeps local runtime state in .ecm-studio/, which should stay ignored by Git.

The SQLite database is only a local projection. It can be rebuilt from JSONL at any time and is not the source of truth.

Development

Install Python and frontend dependencies:

py -m pip install -e .[dev]
npm install --prefix ui

Run the Vite dev server and launch the desktop shell against it:

npm run dev --prefix ui
py -m ecm_studio --dev-ui http://localhost:5173

Build the frontend assets:

npm run build --prefix ui

Run checks:

ruff check src tests scripts
pytest -q
npm test --prefix ui
npm run typecheck --prefix ui

Packaging And Releases

The Python package uses Hatchling and reads its version from src/ecm_studio/__init__.py.

Cut a release from a clean working tree:

python scripts/release.py 0.1.1
git push origin master v0.1.1

The publish.yml workflow builds the React UI, stages it into the wheel, checks the distribution with Twine, verifies packaged UI assets, and publishes tagged v* releases to PyPI through trusted publishing.

Open the next development cycle after a release:

python scripts/release.py --post-release 0.1.2.dev0
