Basic Reference Set Data Structure |
Each
is identified and named by a
in the
metadata hierarchy. Therefore the reference set is identified by a concept identifier (an
Specref |
---|
PreSpace | false |
---|
RefType | data type |
---|
t | SCTID |
---|
|
).
...
- Individual reference set members are uniquely identified by a identifier represented as a
Specref |
---|
PreSpace | false |
---|
RefType | (data type) |
---|
t | UUID |
---|
|
. - Each reference set member belongs to a single reference set, and it is linked to that reference set by the field.
- Each reference set member is also associated with a single referenced component by its
Specref |
---|
PreSpace | false |
---|
RefType | (field) |
---|
t | referencedComponentId |
---|
|
field. The referenced component may be a , , . If the referenced component is a concept that identifies another reference set than , that reference set may be considered to be the target of the reference. - Like , reference set members can be versioned to inactivate or change the status of the member. So there may be several rows in a file and in this case the one with the most recent effectiveTime before or equal to the point in time under consideration represents state of that reference set member. If the field of this row is false ('0'), then the reference set member is at that point in time, which means that component it refers to is not a member of the reference set. If the field is true ('1'), then the component referenced by the
Specref |

field is deemed to be a member of the .
