This is an import for time series published using the TAHMO API. 

FEWS configuration

In order to activate the TAHMO import as a FEWS import, it is required to set up a TimeSeriesImportRun module configuration file and an accompanying IdMap file.

The TAHMO import will take the serverUrl and append it with "stations" to obtain information about the available locations. It will then use the location id's to construct the query url's for the timeseries as such: "<serverUrl>/timeseries/<locationId>/hourly?startDate=...&endDate=...". 

Example Import configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<timeSeriesImportRun 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/timeSeriesImportRun.xsd">
