The service interface layer is the layer for the display of capabilities, including the extensions of exising interfaces and new interfaces.

• Extending exsiting interface

The extension of existing interfaces in SuperMap iServer mainly focuses on REST service interfaces. The JaxrsServletForJersey and RestServlet service interface implementation classes correspond the Restlet and JAX-RS mechanisms respectively. The extensions include:

• Degfining REST resource  Restlet and  JAX-RS mechanisms
• Extending encoder
• Extending decoder

SuperMap iServer provides two implementation mechanisms for REST services: Restlet and JAX-RS. When creating domain resources, extensions based on JaxrsServletForJersey and RestServlet interfaces are different. Users need to choose the property machamism.

• Restlet-based domain resource extension
• JAX-RS-based domain resource extension

• Defining new Service Interface
