Specializing a Descriptor Template
When a new
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set |
|---|
|
is created in an
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | extension, |
|---|
|
it must (by default) conform to the reference set descriptors of its closest supertype (if one exists). Creation of a description template for a new
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set |
|---|
|
is optional in an extension, if the reference set has a supertype which itself has a descriptor template.
However, it is possible for a
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set |
|---|
|
to specialize the descriptor template of its supertype, by creating a copy and replacing the
| Concept |
|---|
| t | 900000000000458008 | Attribute description | |
|---|
| ShowFormat | inline |
|---|
|
or
| Concept |
|---|
| t | 900000000000459000 | Attribute type| |
|---|
| ShowFormat | inline |
|---|
|
values with a subtype.
For example, if a
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set |
|---|
|
has a descriptor, in which the
| Concept |
|---|
| t | 900000000000458008 | Attribute description | |
|---|
|
=
| Concept |
|---|
| t | 449608002 | Referenced component | |
|---|
| ShowFormat | inline |
|---|
|
and the
| Concept |
|---|
| t | 900000000000459000 | Attribute type| |
|---|
|
=
| Concept |
|---|
| t | 900000000000460005 | Component type | |
|---|
|
, then the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set's |
|---|
|
subtype may replace this descriptor with one in which the
| Concept |
|---|
| t | 900000000000458008 | Attribute description | |
|---|
|
=
| Concept |
|---|
| t | 900000000000460005 | Component type | |
|---|
| ShowFormat | inline |
|---|
|
and the
| Concept |
|---|
| t | 900000000000459000 | Attribute type| |
|---|
|
=
| Concept |
|---|
| t | 900000000000461009 | Concept type component | |
|---|
|
(since
| Concept |
|---|
| t | 900000000000461009 | Concept type component | |
|---|
| ShowFormat | inline |
|---|
|
is a subtype of
| Concept |
|---|
| t | 900000000000460005 | Component type | |
|---|
|
). In this way, the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | reference set |
|---|
|
descriptors may be specialized for use by the subtypes of the
| Gloss |
|---|
| PreSpace | false |
|---|
| t | reference set |
|---|
|
.
