[GeoNetwork-users] batch updating of metadata and problem with thumbnails

[Piotr P. <pio...@gm...>]

Hello,
We have in Geonetwork 7220 datasets described by metadata and thumbnail.
Some information in all metadata are changed so we generated new 7220 
xml files with updated metadata but it is no need to update thumbnails.
How to update in Geonetwork metadata, which already have had thumbnails 
? (we don't want to upload thumbnails once more)

We try the process Batch import. After update we can see in METADATA 
table that records are not updated but deleted and created with the same 
UUID but with new ID. This ID is used to create catalog structure of 
thumbnails. So after update we can see that still exist catalog 
structure with old ID and thumbnails but it is also created new catalog 
structure with new ID but without thumbnails.

As a result of update we have updated metadata elements but without 
possibility of viewing thumbnails. Is it possible to change the 
algorythms of batch import ? Batch import should update records like it 
is done by Metadata insert without change of ID and UUID.

May be we did something wrong or it is another way to do it ? Please help.

Regards,
Piotr Pachół
