Following "K. Fine (1999). Things and their parts" this ontology of change (OC) divides all entities into:
Among non-variable entities are manifestations of variable entities. Each such manifestation has its time stamp (being its beginning of existence). The following assumptions introduced by Kit Fine and generalized by "F. Moltmann (2016). Variable Objects and Truth-Making" have been adopted in CO:
IRI: http://ontologies.makolab.com/oc/VariableEntityManifestation
It is a manifestation of variable entity in particular time and space with a particular collection of qualities.
By itself manifestations are entities that do not have different manifestations as different objects at different times and in different worlds or situations.
IRI: http://ontologies.makolab.com/oc/NonVariableEntity
Non-variable entities are entities that do not have different manifestations as different objects at different times and in different worlds or situations.
IRI: http://ontologies.makolab.com/oc/VariableEntity
Variable entities are independent continuants that have different manifestations as different objects at different times and in different worlds or situations.
IRI: http://ontologies.makolab.com/oc/hasLastManifestation
The property assigns the last manifestation to a variable entity.
IRI: http://ontologies.makolab.com/oc/hasManifestation
The property assigns a manifestation to a variable entity.
IRI: http://ontologies.makolab.com/oc/hasPredecessorEntityManifestation
The property establishes the temporal linear order of the manifestations of an entity.
has characteristics: transitive
IRI: http://ontologies.makolab.com/oc/isLastManifestationOf
The property indicates which manifestations of a variable entities are last.
IRI: http://ontologies.makolab.com/oc/isManifestationOf
The property indicates to each manifestation the variable entity it is a manifestation of.
IRI: http://ontologies.makolab.com/oc/isPredecessorEntityManifestationOf
The property establishes the temporal linear order of the manifestations of an entity.

If a variable entity e is manifested at time t by some variable entity manifestation m, then e exists at t, takes a geographical location of m and has all qualities possessed by m in t.
A variable entity possesses a quality q (without temporal reference) if all of its manifestations have this quality q.
