/**
 * 
 * FROM TEIID DOC
 * 
 * The metadata repository type. Defaults to INDEX for Designer VDBs and NATIVE for 
 * non-Designer VDB source models. For all other deployments/models a value must be specified. 
 * Built-in types include DDL, NATIVE, INDEX, and DDL-FILE. The usage of the raw text varies 
 * with the by type. NATIVE and INDEX (only for Designer VDBs) metadata repositories do not 
 * use the raw text. The raw text for DDL is expected to be be a series of DDL statements that 
 * define the schema - see also DDL Metadata. DDL-FILE (used only with zip deployments) is 
 * similar to DDL, except that the raw text specifies an absolute path relative to the vdb 
 * root of the location of a file containing the DDL. See also Custom Metadata Repository. 
 * Use more than 1 metadata element to define multiple sources of metadata.
