Larry Stone commented on DS-202:
--------------------------------
This is a good idea, although it sounds more like a MediaFilter for metadata
than a generator. I would caution against making it a catch-all for *all* the
custom hacks people want to add. For example, the pluggable Persistent
Identifier patch would take care of alternate/additional identifiers like DOIs.
Some metadata changes belong further upstream where they can get human
attention and confirmation during the workflow -- for instance, looking up a
DOI automatically when ingesting an already-published article, that needs some
human review to ensure it's the right one. I would have some use for a hook
like this too, though.
It is not appropriate to do any of this in an event consumer, however:
remember, event consumers should never change the data model, it's too easy to
create infinite loops of events that way.
> Metadata Generator Plugin
> -------------------------
>
> Key: DS-202
> URL: http://jira.dspace.org/jira/browse/DS-202
> Project: DSpace 1.x
> Issue Type: New Feature
> Components: DSpace API
> Affects Versions: 1.6.0
> Reporter: Claudia Jürgen
> Attachments: MetadataGeneratorPluginv4.patch
>
>
> At the moment we got the input/import and the template but no possibility to
> dynamically generate metadata during ingest, which depends on the item or
> it's owning collection ...
> So if you want to create other identifiers (DOI, URN), fetch language
> dependent right statement, use authority files, translate subject terms etc.
> you got no default way to integrate this with DSpace.
> This patch is an outline for a metadata generator plugin along with a
> demonstration of it's possible application. It is intended for discussion not
> straight application.
> The patch based on trunk rev 3729 adds some new classes to org.dspace.content
> Metadata.java (class representing a metadata, in contrast to a DSpace
> metadata value)
> MetadataGenerator.java (the interface)
> DemoGenerator.java (a demo implementation)
> and changes the dspace.cfg and org.dspace.content.InstallItem to demonstrate
> it's possible application.
> Feel free to add your thoughts and comments.
