This use case must be seen in connection with the Use case 3.4.3: Search in GIS data for presentation of GIS content to the user.
Version 1: Removal of contents is needed:
• end-user orders certain layers and a DIP0 is created from AIP
• part of the DIP0 content is removed by the archivist; the event is logged in DIP PREMIS metadata
• the archivist confirms that DIPu is ready
Version 2: Modification of GML file is requested:
• end-user orders only part of the layer, which contains e.g. data sets for an entire country
• the DIP0 is created from AIP • part of the DIP0 content is extracted, modified by an IT/GIS specialist using a special tool, and inserted again into the DIP; all modifications should be back-traced (log file is created and added to the DIP; the fact that DIP content was changed is also recorded in PREMIS, title of changed computer files is also not the same as title in DIP0)
• a DIPu is created, the end-user will also get the reference for the (log) file, in which changes are logged; the user will thus be aware that the content has been modified
• the archivist confirms that the DIPu is ready
