16 UnitConversionsDescriptors

Each UnitConversion support mapping external to internal units configured in DELFT-FEWS can be registered in the UnitConversionsDescriptors configuration.

From Delft-FEWS version 2008.03 it is no longer required to identify the UnitConversion to DELFT-FEWS. If this UnitConversionsDescriptors file does NOT exist or the individual reference to an UnitConversion is not present, the system will assume the corresponding UnitConversion file exist within the UnitConversionsFiles directory. This functionality is similar for IdMap(Descriptors), FlagConversion(Descriptors) and TravelTimes(Descriptors.

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

UnitConversionDescriptors 1.00 default.xml

UnitConversionDescriptors       Fixed file name for the UnitConversionDescriptors configuration

1.00                                            Version number

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