Install and Create a Project

Check the prerequisites, including when SysIDE or sysand is needed.

Install

Install the command for your project:

npm install @memoarchitect/tools

Then run it through your package manager:

npx memo --help

For a source checkout:

git clone https://github.com/memoarchitect/memo-tools.git
cd memo-tools
corepack enable
pnpm install
pnpm run build
pnpm run example:validate

Create a model project

npx memo init my-device
cd my-device

The scaffold contains the active MEMO profile and starter SysML source. Keep project-specific requirements, risks, architecture, and evidence here—not in the installed ontology package.

It also contains analysis/Samples/, with ready-to-run notebooks for model health, architecture hotspots, change impact, charts, an ownership graph, and a model inventory table. To use them:

python -m venv analysis/.venv
source analysis/.venv/bin/activate
python -m pip install jupyterlab syside
cd analysis
jupyter lab --port 8888

Syside must be configured with a valid license. The notebooks use its tolerant loader so diagnostics can be inspected even before the model is fully clean.

Check the resolved vocabulary

npx memo ontology show

This is the quickest way to see the layers, element kinds, relationships, and rules available to the project.

Validate immediately

npx memo validate .

Commit the project only after the scaffold resolves and validates in the same environment your team will use.
