IdentifiedObjects	Utility methods working on arbitrary implementations of the IdentifiedObject interface.
NamedIdentifier	An identification of a CRS object which is both an identifier and a name.

Package org.geotoolkit.referencing Description

Reference system implementations. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the Geotk implementation.

This package provides implementations for general positioning, coordinate reference systems (CRS), and coordinate transformations. Coordinates can have any number of dimensions. So this implementation can handle 2D and 3D coordinates, as well as 4D, 5D, etc.

This package provides a special implementation of identifier, which is also a generic name. By implementing those two interfaces, it is possible to use the same kind of object for specifying both the main identifier and the aliases of an identified object.

All factory methods are capable to find an object using an unscoped (or local) name. However, in order to avoid potential conflict, it is recommended to use scoped name when possible. For example even if both can work, prefer "EPSG:9624" instead of "9624" for the affine transform in order to avoid potential conflict with an other authority using the same code number.
