The

Gloss

Space	true
t	component

identified by the

Specref

RefType	(field)
t	targetComponentId

must be an instance of the same class of

Gloss

Space	true
t	component

as the

Gloss

identified by the referencedComponentIdfor referencedComponentId for all |Historical association|

Gloss

Space	true
t	reference sets

apart from the |REFERS TO

Gloss

Space	true
t	concept

association

Gloss

t	reference set

|.

Within the |REFERS TO

Gloss

Space	true
t	concept

association

Gloss

t	reference set

|, the referenced ComponentId field must be a

Gloss

Space	true
t	description

and the targetComponentIdmust be a

Gloss

t	concept

.

The

Specref

RefType	(field)
t	targetComponentId

is used differently in the |MOVED TO association

Gloss

t	reference set

|. In this case, the

Specref

RefType	(field)
t	targetComponentId

does not refer directly to a replacement

Gloss

t	component

, but rather to the namespace to which the

Gloss

Space	true
t	component

was moved to. The

Specref

RefType	(field)
t	targetComponentId

actually refers to the

Gloss

Space	true
t	concept

that represents the namespace. This approach is used since the organization sourcing the

Gloss

Space	true
t	component

may not always be able to determine the precise reference that is applicable in the receiving organization (namespace). Thus the responsibility for these references lies with the new responsible (receiving) organization.
