Bill Hays commented on DS-655:
------------------------------
I would respectfully disagree with the suggestions to remove DCValue and use
MetadataField or MetadataValue in its place. I believe the use cases for a
simple metadata element bean are distinct enough not to overlay database access
classes with them. No doubt DCValue dates back to a time without multiple
schemas and at the very least has the wrong name. I've used them all in code
I've developed and have found DCValue, despite its deprecated status, to be
necessary.

> Key: DS-655
> URL: https://jira.duraspace.org/browse/DS-655
> Project: DSpace
> Issue Type: Improvement
> Components: DSpace API
> Affects Versions: 1.6.0, 1.6.1, 1.6.2
> Reporter: Bill Hays
> Assignee: Robin Taylor
> Original Estimate: 16 hours
> Remaining Estimate: 16 hours
>
> MetadataExposure provides an exclusion for SystemAdmins but not Community and
> Collection admins who are actually more likely to need access to metadata
> that is restricted to public view. For instance, the default metadata field
> for hiding is dc.description.provenance which is in the purview of Community
> and Collection admins at my location.
> Caveat: The comments in the class state that it is important to have a very
> efficient mechanism and to extend the class by calling
> AuthorizeManager.isAdmin(context, dso) would have a much greater overhead
> than the current AuthorizeManager.isAdmin(context). And for OAI this
> recommendation is not applicable.
> The hidden metadata is still available to all admins using the EditMetadata
> capability, yet this is a burden with the provenance field since it can be
> quite large.
