A GeoRaster Metadata XML Schema
This appendix provides the XML schema definition that is used for GeoRaster metadata.
The following is the definition of the GeoRaster metadata XML schema. (You can also see this definition by querying the SDO_GEOR_XMLSCHEMA_TABLE table, which is described in GeoRaster XML Schema.)

ts type is SDO_GEOMETRY. So it is not included in the metadata

Part 1.4: Data Types for Layer Metadata
For each sub-layer the layerNumber is a positive integer, i.e., layers are
logically numbered from 1 to n if the size of the specified layerDimension is
n. The layerDimensionOrdinate of each sublayer must be in the range of the
dimension and must be in the order of band ordinates.
For objectLayer, the layerNumber should be 0 but its layerDimensionOrdinate
is not used.
