Help with Creating Entity Relationship-Based Faceted Search Filters in DSpace 8.x

[Dibyendra Hyoju]

Hello DSpace Community,

I am working with a DSpace instance where I have enabled entities and am using the default relationship-types.xml. I am attempting to create facets and search filters in DSpace 8 to allow users to filter Publications based on their related Journal, Journal Volume, and Journal Issue. Since these entities reference each other by UUIDs, I’m looking for the best approach to create relationship-based search filters in the discovery.xml.

Use Case & Requirements:

• Publication Collection (Publication entity type): I need to create facets for Journal, Journal Volume, and Journal Issue so users can filter Publications based on these related entities.

Challenges & Questions:

• Facets for UUID-Based Relationships: How can I configure discovery.xml to create search filters that rely on UUID-based relationships (such as journal.title, publicationvolume.volumeNumber, etc.) rather than standard metadata fields?

• Best Practices & Example Configurations: Has anyone successfully configured entity relationship-based faceted search in DSpace 8.x? If so, could you share best practices or working example configurations?

Looking forward to any insights or examples from the community! Any best practices or working examples would be greatly appreciated.

Regards,
