MlDataHub is a dataset storage hub backend. It is intended to be a standard tool for hosting and managing Machine Learning datasets.

This is still a work in progress. It is expected to achieve a Proof Of Concept during October 2017.

On mongo, it is required to set indexes on element.addition_date, element.dataset_id and on `file.sha256`:

db.element.createIndex({'addition_date': 1})
db.element.createIndex({'dataset_id': 1})
db.element.createIndex({'file_ref_id': 1})
db.file.createIndex({'sha256': 1})
