Potential harvesting issues (as signalled on translation to Solr / UI)

[roblokers]

This is meant as a "living list" where we signal potential issues and questions that we run into when setting up the Solr and UI based on the refactored backend with harvesters and augmentation.

They can be caused by (among others):

• low quality or missing source metadata
• processing of the raw harvesting data
• missing or incorrect functioning of metadata augmentation procedures
• incorrect denormalisation of the metadata table structure
• mismatch between metadata and UI design semantics
• misunderstanding of the metadata semantics logic by the reporter of the issue
• misunderstanding of the metadata processing logic by the reporter of the issue
• and probably many other...

27/02/2026 (12.174 records)

• no records from soil mission project in metadata.records (12.174 records)
• no records with revision date in metadata.records
• aggregators needed to map metadata roles to user side roles are missing (e.g. to merge author, Author, creator etc.)
• aggregators needed to map metadata types to user side types are missing (e.g. to merge dataset, Dataset, other dataset type etc.)
• which date to display in UI result list and how to derive that date from the date attriburtes in the metadata records
• which person/organisation to display in UI and how to derive it from the role(s) in the metadata records
• weird records with multiple (all EEA) roles, see id = DAT-14-en or id = eea_s_eu-sdg-15_p_2000-2022_v02_r00
