Motivations

In 2.2 release, only delete action is possible on all metadata records in current search page results. There's no easy way to delete all metadata matching a specific search. This improvement allows users to navigate through search results keeping selected metadata in session. Once selected, user can't apply action to selection set.

Actions available on selection:

• massive delete
• display only selected

Proposal

• 1. A user select a metadata, by checking its checkbox just before title in result list.
• 2. Selected metadata is added to selection manager :
  • 1. Selection manager is null
    • 1. new selection manager created for the type metadata
    • 2. selection manager set in session
    • 3. UUID of the selected metadata added in the new selection manager
  • 2. Selection manager is already existing in session
    • 1 . UUID of the selected metadata added in the existing selection manager

Parameters available for selection : all, none, true, false, single These parameters alloxs differents action on selection manager :

• all : select all metadata in result list (current searcher)
• none : remove all items from selection manager / reset
• true : add the specified item in selection
• false : remove the specified item from selection
• single : clear the selection and add selected element

Backwards Compatibility Issues

Risks

How to deal with harvested / remote metadata :

• should we allow delete actions on it ?
