Example 6 with WorldMapToken

use of edu.harvard.iq.dataverse.worldmapauth.WorldMapToken in project dataverse by IQSS.

the class MapLayerMetadataServiceBean method deleteMapLayerFromWorldMap.

/* 
     * This method calls GeoConnect and requests that a map layer for this 
     * DataFile is deleted, from WorldMap and GeoConnect itself.
     * The use case here is when a user restricts a tabular file for which 
     * a geospatial map has already been made. 
     * This process is initiated on the Dataverse side, without any GeoConnect
     * UI in the picture. (The way a user normally deletes a layer map is by 
     * clicking 'Delete' on the GeoConnect map page). 
     * Otherwise this call follows the scheme used when accessing the 
     * /shapefile/map-it on GeoConnect - we send along a WorldMap token and a 
     * callback url for GC to download the file metadata.metadata
     * Depending on how it goes we receive a yes or no response from the server.
