To optimize metadata management for the ft:sourceName and jira_issuetype metadata keys, proceed as follows:
-
Create a vocabulary containing all existing categories for the sources. Include all the synonyms used in the terminology.
-
Add the appropriate subcategories for the Jira issue types.
-
Go to the Enrich and Clean tab in the Knowledge Hub section of the Administration menu.
-
Select the New rule button and use this vocabulary to generate new metadata based on the
ft:sourceNamemetadata. -
Name the generated metadata
custom_sources_and_jira_types. -
Check the Apply hierarchy check box.
-
Select the Create button.
-
Repeat the process (except for step one) for the
jira_issuetypemetadata.Maintain consistency by using the same vocabulary, custom metadata name, and hierarchy parameter.
-
Select Save and trigger the reprocess.
-
Add the new custom metadata as a facet to the Search page.
Both values from ft:sourceName and jira_issuetype appear in a hierarchical form.
It is possible to expand on the principles outlined in this use case by incorporating additional metadata that involve hierarchies and share commonalities with others.
