Overview
The ZRXP format is a ASCII data exchange file format of Wiski. The file may contain one or more time series.
The time series are defined by a header line that starts with #REXCHANGE.
Directly after this keyword the ID of the time series is defined: #REXCHANGE013S050
After the keyword RINVAL the missing value is defined.
In a complete example of the header
| No Format |
|---|
#REXCHANGE013S050|*|RINVAL-777|*| |
the next items will be read:
- time series ID = 013S050
- missing value = -777
A new time series starts simply with a new header. It also means that the previous series has ended.
The ZRXP files can be supplied in a ZIP file.
More recent versions of ZRXP files may contain a separate location and parameter instead of #REXCHANGE. The location is defined by the keyword SANR and the parameter by CNAME.
The CUNIT keyword defines the unit and the RINVAL the missing value.
Configuration
ZRXP does not identify both a location and a parameter ID. It only has a time series ID. To import these series into FEWS you have to set both the external location ID and parameter ID to this time series ID.
Example of the import module instance:
| No Format |
|---|
<import>
<general>
<importType>WISKI</importType>
<folder>$IMPORT_FOLDER$/zrxp</folder>
....
</general>

Example of the id mapping:
| No Format |
|---|
<?xml version="1.0" encoding="UTF-8"?> <idMap version="1.1" 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/idMap.xsd"> <map internalParameter="H" internalLocation="013" externalParameter="013S050" externalLocation="013S050"/> <map internalParameter="H" internalLocation="013" externalParameter="013S065" externalLocation="013S065"/> ..... |

Note that the status and the interpolation_type are combined to form a flag which can be mapped in the flag mapping. This is done by multiplying the status by 1000 and adding the interpolation_type (example below). The status should also be between 0 and 999.
