IdMaps
IdMaps are defined to map internal location and parameter ID's to external location and parameter ID's. The configuration of these can be done in two ways. In the first separate mappings can be defined for the locations and for the parameters. Although this is the mist efficient method, it is not suitable in all cases, as specific locations may require a different mapping,. A second definition can be created where the mapping is done on the basis of the unique combination of location/parameter. Each IdMap configuration may only use on method of defining mappings to avoid ambiguity.
Each IdMap configured must be registered in the IdMapsDescriptors configuration (see Regional Configuration). The Id used in registering the IdMap is the same as the name of the configuration. When available on the file system, the name of the XML file for configuring an IdMap called for example ImportNWP may be:
ImportNWP 1.00 default.xml
ImportNWP |
Fixed file name for the ImportNWP IdMap. |
1.00 |
Version number |
default |
Unit to indicate the version is the default configuration (otherwise omitted). |

parameter
Mapping of internal to external parameters. Multiple entries may exist.
Attributes;
- internal : Internal parameter Id (must be in the parameters configuration)
- external : External parameter Id (free format string)
- externalQualifier : Optional additional qualifier to uniquely identify a parameter (for use in conjunction with EA-XML schema only.
location
Mapping of internal to external location Id's. Multiple entries may exist.
Attributes;
internal : internal location Id (must be in the location configuration )
external : external location Id (free format string)
map
Parameter/location mapping using unique combination. Multiple entries may exist.
Attributes;
