Summary: Edit an Item using the workflow process
Key: DS-1234
URL: https://jira.duraspace.org/browse/DS-1234
Project: DSpace
Issue Type: Improvement
Components: DSpace API, XMLUI
Affects Versions: 1.8.2, 3.0
Reporter: Nestor Oviedo
Attachments: workflow_edit_modified_classes.zip, workflow_edit.patch
Currently, the only way to edit an item metadata is through the "Admin Item"
section, where a list of all metadata is displayed using textarea elements.
Here there are no constraint checking or help (by hints) or logical metadata
organization. It is just a list o textarea elements labeled whith the
respective metadata name.
This patch allows a user to edit an item by re-inserting it in the workflow
process, as if it was a new submission.
It is important to note that this patch modifies the XmlWorkflow aspect, which
means that this function will be available only for those who have this aspect
enabled.
How does it work?
Navigation class was modified and now, when an Item is shown, there is another
context menu item which points to "handle/xxxx/yyy/edit_item_metadata", only
when the user can edit that item.
That URL is handled by the XmlWorkflow's sitemap.xmap (that was modified to add
the corresponding match component), which invokes the flowscript function added
to the xmlworkflow.js (also modified to add this function).
This flow function invokes some validation functions (added to
XmlWorkflowManager class) and then starts the workflow. This means the
XmlWorkflowItem wrapper is created and the workflow's first step is activated.
Also, the XmlWorkflowManager's archive() method was modified to decide if the
"item to archive" is a new submission or an edited item.
So far, we haven't decided how to manage the un-publish and re-publish tasks
when the item enters and leaves the workflow. An option could be use the
"in_archive" flag. This means that when the item enters the workflow for
edition it remains published.
Also, this modifications might need some addiontional testing.
Attached you will find the patch file, and a zip file containing the modified
files (classes, sitemaps, flowscripts, etc), organized by module.
We would be glad to hear your comments about this patch.
