The question is vague. So I am giving an assumed answer.
The correct answer could be - Temporary.
A datum is theoretical exact plane, or an axis or a point location to which the Geometric Dimensioning and Tolerancing (GD&T) orthe dimensional tolerances are usually referenced to.
The Datum features are either temporary or permanent. A few selected datum features which are in the in-process parts like in the castings, fabrications, forgings, or machinings, might be used temporarily. When the temporary datums have been established, they will then need to establish or evaluate the permanent or the machined datums back into the temporary datums.
