Domain-Model-eXaminer (DMX)

Description

The goal of this process is to perform machine reading over the model codebase in order to automatically extract key metadata about:

• Input files
• Output files
• System requirements
• Software requirements
• Model entry points
• Model descriptions
• Maintainer information

Installation

Pip package

The domain-model-examiner library can be installed via pip:

pip install domainmodelexaminer

Local installation from source

After cloning the repo, the recommended installation is to create a new conda environment and then install from requirements.txt:

conda create --name=dmx python=3.8
conda activate dmx
conda install -c conda-forge uvicorn
pip install -r requirements.txt

Docker installation from source

After cloining the repo, docker install and run:

docker build -t dmx .
docker run -p 80:80 dmx

The API docs will be available at http://0.0.0.0/docs.

Usage

Pip Package

The examine function of module dmx of package domainmodelexaminer takes the following parameters:

• url (str) GitHub or GitLab repo url.
• return_json (bool = True) Returns a JSON string if true, else a YAML string.

and returns either JSON (default) or a YAML string.

The examine function can be imported an executed as follows:

from domainmodelexaminer import dmx
dmx_json_output = dmx.examine("https://github.com/dojo-modeling/dojo")

Local install

List command line options

python dmx.py --help

Process Local Repository

Clone or download the repository of interest. For example:

cd /tmp
git clone https://github.com/jataware/dummy-model.git

Next, analyze this repo with:

python dmx.py --repo="/tmp/dummy-model"

Process Remote Repository

python dmx.py --url="https://github.com/jataware/dummy-model.git"

This creates and deletes a tempory folder 'tmp'.

Output

The application produces a .yaml file with prefix 'dmx-' concatenated with the repo name.

Running the API

Run API:

uvicorn domainmodelexaminer.api:app

The API docs will be available at http://127.0.0.1:8000/docs

Do not use the uvicorn --reload flag, since the app will download the repo to the api folder.
