DSpace 5 with XMLUI enable curation task in submission form

[Flavien M]

Hello,

I am currently trying to configure the input form.
I would like that at the end of the entry of an item some fields are filled automatically.

Examples:
- dc.redaction.author: automatically put the name of the user who just typed the item;
- dc.redaction.datecreation: automatically set today's date.

If I understand correctly, in DSpace the way to reach my goal is to use the curation tasks.

I created a "/dspace/modules/additions/src/main/java/org/dspace/myproject/curate/AddMetadata.java" task.

But I did not understand how to activate this task.

Here are my questions:
- How to enable this task to run automatically at the end of an item?
- How to retrieve the name of the active user (the one who is entering) in the task?
- How to retrieve the date of the day in the task?

I use DSpace 5.10 and XMLUI.

PS : Sorry for my bad English this is not my native language.

Thank you in advance.
Flavien

Hello Flavien,

in our submission process we add metadata automatically. I don't think that the curation tasks are intended  for that. We wrote a separate submission step that runs without any user interaction and configure it in the '[dspace-src]/dspace/config/item-submission.xml'. For example:

'''
<step>
  <processing-class>org.dspace.submit.step.AddMetadata</processing-class>
  <workflow-editable>false</workflow-editable>
</step>
'''

Our step extends the 'AbstractProcessingStep' (http://demo.dspace.org/javadocs/6/apidocs/org/dspace/submit/AbstractProcessingStep.html). In the method 'doProcessing' (http://demo.dspace.org/javadocs/6/apidocs/org/dspace/submit/AbstractProcessingStep.html#doProcessing) you can use the Context-object to get the current user. For the date I would use some Java standard way.

To store all information in specific metadata fields, use the 'itemService.addMetadata'-method (http://demo.dspace.org/javadocs/6/apidocs/org/dspace/content/service/DSpaceObjectService.html#addMetadata). The Item-object that you need for this method will you get from the SubmissionInfo-object.

I hope this helps and kind regards,

Paul Münch

I disagree. There is a fair amount of code in the curation system
specifically to implement attachment of curation tasks to workflows.

How to attach a task to a workflow step: see the link above.

How to retrieve the name of the active user: I am not sure what user
this is. The EPerson who submitted the item should be obtainable
using Item.getSubmitter(). The EPerson who is in the current workflow
step would, as Paul Münch said, be in the request, but that may not be
available in a task. (If it is not, we should fix that.)

How to retrieve the date: which date? The date of submission
should be in the metadata field dc.date.submitted. The current date
is of course obtainable from java.util.Date or java.util.Calendar.

Thank you for the correction! I totally forgot this section in the
documentation, because we use the tasks mostly for manually processes.

Kind regards,
