How the Metadata Engine Constructs a LIBNAME Statement

As noted in Overview of the Metadata LIBNAME Engine, the metadata engine uses information from metadata to construct a LIBNAME statement for a SAS library.

When you submit a metadata LIBNAME statement, you assign a libref to a SASLibrary metadata object. The SASLibrary object is the primary object from which all other metadata is obtained. The metadata defines attributes of the data, such as table and column names. The metadata identifies the underlying engine that processes the data, and how the engine should be assigned.
