The following attributes of a type definition are important
when creating and querying metadata. This information is available
on the
Advanced tab of a type definition’s
Properties window. In addition, you can get this information
by querying the appropriate TypeDefinition metadata object.
specifies the primary SAS Metadata
Model metadata type in the object type’s logical metadata definition.
This is always a PrimaryType subtype in the SAS Metadata Model.
specifies a name that uniquely identifies
the type definition in the SAS type dictionary.
Many type definitions
use the same SAS Metadata Model metadata type as the primary object
in their logical metadata definition. For example, the type definitions
for both the SASReport and InformationMap object types specify Transformation
as their metadata type. To ensure that the appropriate type definition
is used to retrieve an object type’s logical metadata definition,
SAS wizards and procedures that create metadata store the TypeName
value that is appropriate for each object type in the primary object’s
PublicType attribute. When listing objects, the PublicType value is
used with the MetadataType to identify the object type.
specifies the object type that contains
the object. This is usually Folder, but it can be another object type
from the SAS type dictionary. For example, a Column object is contained
by a Table object.
specifies
the association name that links the primary object in a logical metadata
definition to its container. Object types that are contained by a
folder have a Trees association to the folder. (A folder is represented
by an object of the Tree metadata type in the SAS Metadata Model.)
A Column object has a Table association to the table that contains
it.
specifies
a double value in the form MMMmmbbbb.0 that
indicates the type definition’s current usage version. M=major version, m=minor version,
and b=build.
SupportedObjectVersionMin
specifies a double value in the form MMMmmbbbb.0 that indicates the minimum usage version supported for this type
definition.
SupportedObjectVersionMax
specifies a double value in the form MMMmmbbbb.0 that indicates the maximum usage version supported for this type
definition.
Clients can specify a type definition
version for an object by storing a version value in the primary object’s
UsageVersion attribute. The DefinitionVersion, SupportedObjectVersionMin,
and SupportedObjectVersionMax attributes indicate the range of versions
that are available for a type definition. For more information about
the TypeDefinition attributes, see
