Key Concepts
In the /theia folder is a Django app that encapsulates access to the configuration objects and allows the creation of imagery requests. The API can be accessed at http://localhost:8080/api
The domain model of the Django app specifies the objects for creating pipeline configurations, as well as objects to track the processing of a particular request.
Adapters encapsulate the acquisition of imagery from a particular provider. They are responsible for receiving an ImageryRequest and producing one or more JobBundle objects for subsequent processing.
Each discrete operation on a JobBundle is represented by an operation. Operations implement the AbstractOperation class.
Celery tasks are specified in files named tasks.py. Tasks that will likely be shared by all adapters are placed in /theia/tasks.py, while tasks specific to a given adapter (like USGS' task wait_for_scene) can be specified from within that adapter's code.
The test suite is in this folder and can be invoked by pipenv run tests
