Description

Initial port of the DSpace-CRIS authority framework into core DSpace, enabling real-time entity lookup, confidence-based linking, and automatic graph maintenance through server-side consumers.

On the UI this PR introduces a new way to link authorithy controlled metadata to the related item, generating a link in search results or item page, this connection is handled in submission. (for configuration check the rest PR)

Through a rest configuration, is possible also to activate an "auto-fill" functionality, that will populate the submission fields based on the selected value (value must be authority controlled).

Exaple of config in cris-authority-metadatagenerator.xml:

<bean class="org.dspace.content.authority.ItemSimpleAuthorityMetadataGenerator">
    <property name="authorityName" value="AuthorAuthority"/>
    <property name="keyId" value="person_identifier_orcid"/>
    <property name="useForDisplay" value="true"/>
    <property name="useAsData" value="true"/>
    <property name="schema" value="person"/>
    <property name="element" value="identifier"/>
    <property name="qualifier" value="orcid"/>
    <property name="singleResultOnAggregate" value="true"/>
</bean>

auto-fill.webm

The information of the related item are previewed via a new pop-up component enabled on hover, visible on both search results and item page:

In addition the PR introduce also multilanguage support for authority controlled vocabularies, to achieve this we need to have a vocabulary version for each language enabled by the property: webui.supported.locales

For instance if we have

webui.supported.locales = en, de

we can create a translated vocabulary (srsc_de in this example) and then configure the authority as follows (authority.cfg):

vocabulary.plugin.srsc.hierarchy.store = true
vocabulary.plugin.srsc.hierarchy.suggest = true
vocabulary.plugin.srsc.delimiter = "::"
vocabulary.plugin.authority.store = true
authority.controlled.dc.subject = true

This will enable to display the translated value in the UI, if the language matches the translated one:

EN:

DE:

This last feature will be consolidated later in the merger with the cust layout functionality from CRIS (at the moment this is not presente in the exact same way on CRIS as there we rely on the layout feature that is not yet in scope).
The implementation will remain anyway as it will be useful also as fallback for not configured layouts.

Instructions for Reviewers

Once the item relation is enstablished (submitted) the metadata will be linking to the related item, with a preview of metadata visible on link hover.

The new configuration for the pop-hover preview is available in default-app.config.ts, under the name:

metadataLinkViewPopoverData

It provides the opportunity to customize the preview metadata based on entity type.

In submission is possible also to configure specific icons for each source of authority, see config:

sourceIcons (under authority config)

In general for the newly added configuration you can refer to the config.example.yml file.

Once submitted, the authorithy controlled value should then result in a clickable link the search results (if the value is displayed) and in a clickable link in the item page (see images above).

Is possible to configure also auto-fill and generated metadata based on the authority (see descriptio or rest PR).

For the multilanguage support on vocabularies a translated vocabulary and submission form are needed, in addition to the properties based on the vocabulary name and metadata (see description).

List of changes in this PR:

Enhanced search results and item page with linkable related items (authority controlled)
Added new popover component for metadata preview on hover.
Implemented custom pipe for icon/info handling in onebox component.
Improved editing of authority via admin view, improved handling of search filters (filter by authorithy not value).
Implemented auto-fill functionality in submission.
Added support for multilanguage visualization of controlled vocabulary values in item page.

Checklist

This checklist provides a reminder of what we are going to look for when reviewing your PR. You do not need to complete this checklist prior creating your PR (draft PRs are always welcome).
However, reviewers may request that you complete any actions in this list if you have not done so. If you are unsure about an item in the checklist, don't hesitate to ask. We're here to help!

• My PR is created against the main branch of code (unless it is a backport or is fixing an issue specific to an older branch).
