What's New in SAS 9.4 Metadata Model: Reference
| Overview |
The SAS 9.4 Metadata Model includes three new metadata types, modifications to several existing metadata types, and documentation enhancements.
New Metadata Types
- The ColumnHierarchy metadata type
enables you to assign columns to a hierarchy for the associated data table. For more information, see
the Relational Submodel.
- The SecuredLibrary metadata type describes a Base SAS library that relies on the SAS Metadata Server to authorize access by users and groups. A SAS program cannot access data that is described by a SecuredLibrary object unless the caller can authenticate to the SAS Metadata Server and has appropriate permissions defined on the SecuredLibrary object. For more information, see the Resource Submodel.
- The SecuredTable metadata type describes a SAS data file in a secured Base SAS library. A SecuredTable object inherits the permissions defined on its associated SecuredLibrary object, unless an administrator explicitly defines permissions on the SecuredTable object. For more information, see Relational Submodel. Also see SecuredLibrary and SecuredTable Associations in Diagrams for Relational Metadata Types.
Enhancements to Existing Metadata Types
- The Root metadata type has a new attribute, SecTransctxt. Modifications to the Root metadata type affect all metadata types. For more information, see the Root metadata type.
- The SASPassword metadata type has several modifications.
- The metadata type has a new attribute, Encryption.
- The length of the Password attribute was extended from 128 characters to 256 characters.
- The metadata type has a new association, AssociatedSecuredLibrary.
For more information, see the SASPassword metadata type.
- The DataTable metadata type has a new association, ColumnHierarchies. For more information, see the DataTable metadata type.
- The DeployedComponent metadata type's SourceConnections association has been modified. The association is now ordered. For more information, see the DeployedComponent metadata type.
Enhancements to Documentation
Requirements for using slashes (/, \), square brackets ([]), and control characters in Name values are clarified. See Id and Name Attribute Requirements in "Understanding Root Properties."
Additional Enhancements
In the second maintenance release for SAS 9.4, the AuthenticationDomain metadata type has two new attributes: OutboundOnly and TrustedOnly. For more information, see the AuthenticationDomain metadata type.
