The GatewaysEngine is a directory of Content Repositories descriptors. All the CR that the GatewaysEngine manages, are associated through a unique ID, to a ContentRepositoryDescriptor that contains all the information related to how a CTM can access the given CR (the gateway associated to it). The CTM is integrated in the tool/application. For details on the CTM component, please refer to chapter 2.2.2. When a new CR is added for exploitation, the GatewaysEngine has all the information about accessing it (this internal descriptors are not present at the KP-Lab tool level). This way, the addition of a new CR can be done dynamically during exploitation.
