Configuring the Import

To make the importer known to FEWS, the import module has to be declared in the moduleInstanceDescriptors.xml in the RegionConfigFiles directory of the FEWS configuration:

<?xml version="1.0" encoding="UTF-8"?>
<moduleInstanceDescriptors xmlns="http://www.wldelft.nl/fews"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
		xsi:schemaLocation="http://www.wldelft.nl/fews
		http://fews.wldelft.nl/schemas/version1.0/moduleInstanceDescriptors.xsd" version="1.0">
...
	<moduleInstanceDescriptor id="ImportCEMIG-anna25">
		<moduleId>TimeSeriesImportRun</moduleId>
	</moduleInstanceDescriptor>

...
</moduleInstanceDescriptors>
