22 SDO_CSW_PROCESS Package (CSW Processing)

The MDSYS.SDO_CSW_PROCESS package contains subprograms for various processing operations related to support for Catalog Services for the Web (CSW).

To use the subprograms in this chapter, you must understand the conceptual and usage information about Catalog Services for the Web in Chapter 16.

Table 22-1 lists the CSW processing subprograms.
