CartoWeb offers two access modes e as aweb service CartoClient and CartoServer then interact using remote procedures based upon SOAP http www w3 org TR soap12 e as a standalone application Procedures are then performed directly between CartoWeb components bypassing the SOAP calls Direct mode SOAP mode 11 Architecture 3 aas a Multi client mode Of course it is possible to combine the above architectures as shown on the following figure 3 4 Modularity Projects and Plugins 3 4 1 Plugins 12 Architecture CartoWeb buzzword is modularity The application is built as a set of bricks that interact with each other Those bricks are called plugins Each plugin performs a special group of tasks such as map browsing layers management images properties users permissions data objects querying exportation and much more CartoWeb is shipped with a set of standard plugins that can be separately activated or not It is possible to write your own plugins or customize existing ones as well H H H H H L d SZ P mee Se Regular plugins including how to configure them are precisely described in Part II User Manual For more information about how to write or customize plugins see Chapter 2 New Plugins 3 4 2 Projects 13 Architecture Projects are used to separate the upstream application from its customizations They contains all the modifications and adaptatio
