This toolchain allows to generate REST APIs from instances of the WoTDL OWL Ontology, which is part of the GrOWTH approach for Goal-Oriented End User Development for Web of Things Devices. [1] WoTDL has been listed on the LOV4IoT Ontology Catalogue.

It uses a model-to-model transformation to generate an OpenAPI specification. The Flask-based REST API is generated using OpenAPI Generator.

• Python 3.7.0+
• for python requirements see requirements.txt
• openapi-generator 3.3.4+

Get the dependencies:

pipenv install
pipenv shell

Adapt the IN variable to point to your ontology instance and run the model-to-model transformation:

python m2m_openapi.py

Run the model-to-text generation:

./m2t_openapi_flask.sh
