= list = 
This service lists different aspects of ADEI server configuration like configured data sources, supported export formats, etc. The required aspect is defined by ''target'' property.

== Supported targets ==
'''Data Sources'''
 * ''servers'' - Returns list of configured data sources
 * ''databases'' - Returns list of available databases within data source. This request returns both active and historical databases.
 * ''current_databases'' - Returns list of available databases within data source. Only currently active databases are returned.
 * ''groups'' - Returns list of available logging groups. If the ''db_server'' and ''db_name'' properties are specified, only groups belonging to the specified database are returned. Otherwise the service returns complete list of logging groups available in all configured data sources.
 * ''masks'' - Returns list of configured masks withing specified loggroup
 * ''items'' - Returns list of available data items (channels) within specified loggroup
'''Data Intervals'''
 * ''experiments'' - Returns list of experiments
 * ''window_modes'' - Returns list of standard window sizes
'''Data Export'''
 * ''formats'' - Returns list of supported export formats
 * ''sampling_rates'' - Returns list of supported sampling rates (optional, for data export)
 * ''export_window_modes'' - Returns list of supported export modes (interval)
   * Selection
   * Currently opened data window
   * Whole experiment
 * ''export_mask_modes'' - Returns list of supported export modes (item mask)
   * Current group only
   * All groups having the mask with specified name
   * Complete data source
   * Everything
'''Data Aggregation'''
 * ''aggregation_modes'' - Returns list of supported data aggregation modes (MEAN, MMAX, ...)
 * ''interpolation_modes'' - Returns list of current interpolation modes
 * ''gaps_modes'' - Returns list of available modes for reporting missing data
 * ''marks_modes'' - Returns list of available modes for reporting positions of real data points

== Mandatory Properties ==
 * ''target'' - List target (see section above)
 * Other optional properties could become mandatory depending on target type

== Optional Properties ==
 * [wiki:adeiParam_db_server db_server ] - Data source 
 * [wiki:adeiParam_db_name db_name ] - Database name
 * [wiki:adeiParam_db_group db_group ] - Log Group

== Returned Result ==
XML document listing requested target or error message. The following format of XML document should be expected:
{{{
<result>
 <Value value="<item_id>" name="<item_title>"/>
 <Value value="<item_id>" name="<item_title>"/>
 ...
</result>
}}}
The additional node attributes may be used to provide additional information. Example (if listing all available groups, the actual server, database and group ids are explicitly specified):
{{{
<result>
 <Value value="katrin__hauptspektrometer__0" name="HauptSpektrometer -- hauptspektrometer -- Nord-West" db_server="katrin" db_name="hauptspektrometer" db_group="0" />
 ...
</result>
}}}
If the error is occurred during request processing, the error message is returned. The following format is used:
{{{
<result>
 <Error>Unknown list target (wines) is specified</Error>
