What's New in the SAS 9.1 and 9.1.3 Metadata LIBNAME Engine
Overview
The metadata engine provides secure access to SAS data. By incorporating metadata, this engine augments and controls access to the data.
Note: This section describes the features of the SAS metadata engine that are new
or enhanced since SAS 9.0. 
Details
- The metadata engine, in conjunction with the SAS Open Metadata Architecture Authorization Facility, enables an administrator to specify user privileges in order to control which data the users are allowed to access.
- The new LIBURI= and LIBRARY= options in the LIBNAME statement provide additional methods for referencing the SASLibrary metadata object.
- The new METAOUT= option specifies access to tables in the data
source.
- The METAOUT= option in the LIBNAME statement enables you to specify access to a library.
- The METAOUT= data set option enables you to specify access to a specific table.
- Beginning with SAS 9.1.3 Service Pack 4, with the default behavior of the engine (METAOUT=ALL), you can no longer create or delete tables or their associated metadata. You can insert, update, and delete observations in a table. Metadata must be present for you to access the table.
- Beginning with SAS 9.1.3 Service Pack 4, when METAOUT=DATA is specified for a table, the metadata engine behaves more like the underlying engine that is defined in the metadata; for example, data set options can be passed directly to the underlying engine.
- Beginning with SAS 9.1.3 Service Pack 4, you are advised to use the METALIB procedure instead of METAOUT=META to create, update, or delete metadata. The METAOUT=META value is not expected to be supported in the next release of the software. (For information about PROC METALIB, see the chapter about SAS language metadata interfaces in SAS Open Metadata Interface: Reference).
- Beginning with SAS 9.1.3 Service Pack 4, SQL implicit pass-through is supported.
