Configuration archiving by Delft-FEWS

...


Delft-FEWS can export the current configuration to the archive via the ArchiveExportModule (exportConfig activity). The configuration thus is exported as part of the workflow. The associated root directory structure of the Delft-FEWS export for this type of dataset is as follows:
<archiveRoot>/<config>/<areaId>/<yyyymmdd>/
The date refers to the revision date of the configuration. The file name typically holds the revisionId.
The exportArchiveModule.xsd has a dedicated exportConfig section to setup the export of the Configuration (see Figure 4.6). This is due to be revised as the same relativePeriod based export mechanism should be adopted for checking what to export (see Table 4.5).

Archiving rating curves by Delft-FEWS

...


Delft-FEWS can export rating curves to the archive via the ArchiveExportModule (exportRatingCurves activity). The entire history of the rating curves is exported. The associated root directory structure of the Delft-FEWS export for this type of dataset is as follows FEWS-10198: update directory structure to above setup:
<archiveRoot>/ratingcurves/<areaId>
The configurator can choose between exporting the full set or just the rating curves that have changed, with or without modifier changes.
The exportArchiveModule.xsd has a dedicated exportRatingCurve section to setup the export of the Configuration. Table 4.6 and Figure 4.7 discuss the general section.
