12 ModuleInstanceDescriptors

Each module configured in DELFT-FEWS must be registered in the ModuleInstanceDescriptors configuration. This is required to identify the module to DELFT-FEWS (the name is free format), but is also required to define the type of module through reference to the moduleDescriptors defined (see system configuration).

When available on the file system, the name of the XML file for configuring the ModuleInstanceDescriptors is for example:

ModuleInstanceDescriptors 1.00 default.xml

ModuleInstanceDescriptors       Fixed file name for the ModuleInstanceDescriptors configuration

1.00                                            Version number

default                                       Flag to indicate the version is the default configuration (otherwise omitted).
