Help me find the modern terminology for an old philosophical concept

[Posy McPostface]

There used to be a term called 'logical space' where objects have their properties (or facts) defined by their relation to other objects in said 'logical space' along with their potential modalities included in this sort of 'space'.

Here is the definition provided here:

Logic, metaphysics The possible ways in which objects can combine into states of affairs . The term is used by analogy to physical space, which presents us with a set of locations, positions, or places that can be occupied by objects in relation to other objects. Logical space is thus the ensemble of logical possibilities , a universe composed of all possible-and-existing states of affairs and all possible-and-non-existing states of affairs. For Russell , it is a system of proper logical relations . Wittgenstein makes use of this conception to show that facts do not compose the world as a heap and that there is a structure of logical relations amongst them. The world is the totality of facts in logical space. “The logician is led to give the name ‘space’ to any system of relations having the same or similar logical properties.” Russell, Collected Papers of Bertrand Russell , vol. VI

I've heard the modern term that is closest to the 'logical space' one is 'state space'. Is that the right 'updated' definition for an antiquated phrase?

I think state space is the correct term no.
