  • Ticket #2615 – Description

    v4 v6  
    44 * Too few `EventLogs` are created for some deletes 
    55 
     6== Notation == 
     7 
     8Below are listed several possible workflows for what a user might want to delete. Each scenario provides the following information: 
     9 
     10 * REQUEST: the user request for what type should be deleted (ids are omitted). Types are represented as xpath-like statements, some which don't actually exist as types "Comments" represent a combination of fields, like `type=Annotation + namespace="comment"`. 
     11 * DELETES: the types which would be deleted '''regardless''' of permissions and optimistic locks. The only thing which will prevent such a delete is a fatal DB error which will throw a `FailedDeleteExcception` 
     12 * OPTIONS: the paths listed under “OPTIONS” can be handled in on of the following ways: 
     13    * ORPHAN - the objects are left alone, i.e. unlinked from the target. 
     14    * REAP - delete the objects if they would be orphaned. 
     15    * SOFT - delete the objects, but continue if delete is not possible. 
     16    * HARD - delete the objects at all costs. Transaction will fail if not possible. 
     17 * BLOCKER: if this path is filled, then the delete will fail with a `BlockedDeleteException` 
     18 
     19== Types == 
     20 
     21Currently types are separated into two categories. When providing reports to users it should suffice to start at these roots. 
     22 
     23=== /Roots === 
     24 * /Projects and /Datasets 
     25 * /Screens and /Plates 
     26 * /Images (includes Pixels, binary data, etc.) 
     27 * /Rois (if not already under /Images) 
     28 * /FS - each FS mount is also a root 
     29 
     30=== /Orphanable === 
     31 * /Tags 
     32 * /Terms 
     33 * /FileAnnotations 
     34 
     35'''NB''': ''We may want to consider whether or not there should be two types of annotations. Ones which are orphanable and ones which are not.'' 
     36 
    637== Scenarios == 
    7 description of possible workflow 
    8  * Select an image to delete.  
    9    * Annotations like Comments, rating should be deleted at the same time. 
    10    * Rois if any should be deleted. 
    11    * Ask user if wants to delete annotations that can be shared e.g. tag, ontology, document 
    12    * Settings, acquisition data should be deleted too (since we don't share them) 
    13  * Select a dataset to delete. 
    14    * Need to option to delete contents (similar to Eclipse) i.e. delete images 
    15    * Same options as before. If Tag, documents have to be deleted, then the same strategy will be applied for images.
