What Is a “Semi-Fungible” Token in the Context of ERC-1155?

A semi-fungible token is an asset that is fungible for a period but then becomes non-fungible, or vice-versa. For example, a concert ticket is fungible (interchangeable) before the event, but after the event, it becomes a unique, non-fungible collectible.

ERC-1155 handles this by allowing the same contract to manage both the fungible and non-fungible states of the token.
