In Koha 3.0, the item status is set without duration. We will add a feature to explain how long a given status will be used, and which status must be set after that.
That will be usefull, for example, to have a book with status “new book”, that is changed to “available” after 1 month. Or to have a book with status “lift”, changed to “reserve” after 1 day…
— We could define some status workflow in a table. table status workflow id code description status list
