Learning Resource draft import from table
On the long term we aim for harvesting learning resources from a yet-to-setup instance of OpenedX.
As a temporary solution, a draft pipeline should be created which reads the collected metadata on EduTrain resources and imports the metadata into the KH. Later, we re-use the pipeline and change the input source to use the OpenedX API instead of the manually collected table.
The edu train resources will be modeled as instances of https://schema.org/LearningResource . The class LearningResource
must be created in kh_populator_model
.
