Requirements

SIS requires Java 7 Standard Edition.

Classes naming

Implementations of GeoAPI interfaces usually (but not always) begin with Abstract, Default, Simple or General prefix. The Abstract prefix is used when a class is abstract according ISO specifications - it may or may not be be abstract in the Java sense. The General prefix is used when an implementation is designed for use in the general case, as opposed to other implementations specialized for a fixed number of dimensions or other conditions. Implementations specialized for a fixed number of dimensions are suffixed with 1D, 2D, 3D or 4D rather than being prefixed.

Classes that are not GeoAPI implementation are usually not prefixed by any of the above.
