The 900000000000456007 |Reference set descriptor| is a reference set that is used to specify the format of all reference sets included in a release. The data type and meaning of the referenced component and each additional field within each reference set is described by this reference set .
Reference set descriptor can be used to define
|Part of Primary Key|
|NO||YES (Full /Snapshot)|
The inclusive date or time at which this version of the identified reference set member became the current version.
Note: In distribution files the effectiveTime should follow the short ISO date format (YYYYMMDD) and should not include the hours, minutes, seconds or timezone indicator.
Specifies the name of an attribute that is used in the reference set to which this descriptor applies.
Set to a descendant of 900000000000457003 |Reference set attribute (foundation metadata concept)| in the metadata hierarchy, that describes the additional attribute extending the reference set .
Specifies the data type of this attribute in the reference set to which this descriptor applies.
Set to a descendant of 900000000000459000 |attribute type (foundation metadata concept)| in the metadata hierarchy, that describes the type of the additional attribute extending the reference set .
Specifies the position of this attribute in the reference set to which this descriptor applies. A zero value identifies the referencedComponentId within the reference set. Other values specify an additional attributes by its position relative to the referencedComponentId. Within a particular descriptor, attributeOrder values for a particular referencedComponentId must be contiguous.
At least one row must exist for each reference set included in a release. This row must have an attributeOrder value of '0' and an attributeType of ' component type' (or one of its descendants). The referencedComponentId identifies the reference set defined by the descriptor.
There is one additional row for each additional column present in the specified reference set .
Creation of a Reference set descriptor is optional when creating a reference set in another Extension. If a descriptor is not created, the descriptor of the closest ancestor of the reference set is used when validating reference set member records.
Values in the Reference Set are populated from:
