Content preview - S3 #505
Description
- the preview content should be in some another (new) table
When a zip file is added to the item, there is a Preview button. This button rolls down all zipped files, which are always generated by this action. We don't want that! In DSpace5, this content is in the metadatavalue table from which these values are only loaded by this action. We want to create a NEW TABLE. The values will be generated only once and then saved in this table. After the second click, the values will only be loaded from this table.
- Design the new table, column names, and types.
- When will the data be generated? By script, during startup, installation, or first click?
Useful notes: clarin-dspace.cfg -> file.preview.enabled = TRUE, MetadataBitstreamRestRepository = get FilePreviewContent.

Research: The idea is to save FileInfo into database and make many2many relationship between FileInfo. For now I created new database object, but maybe the FileInfo can be database object.
