We need to check those description in section 4.6.

It is anticipated that notebooks will both evolve and become technically obsolete over time. It is therefore important to manage the natural lifespan of a notebook. In addition to the notebook being physically stored in a trusted repository and made discoverable the threat of technical obsolescence must be managed. A notebook should only be archived and managed in its active state if there is a reasonable expectation that it will remain usable for 5 years. By recording dependencies the chance of this being the case is greatly increased. Notebooks unlike data should be considered for medium term preservation only. You will also have removed the most common cause of notebook technical obsolescence.
