• Find out if there is a way for Timeline viewer is support the ETDF format date: 1783 to 1784

Solution

PHP doesn't accept the format of 1783 to 1784 so we can use rewrites to format as accordingly

• Go to View > TimelineJS Solr-based View > Edit
• Under Fields > Content datasource: Date Created
• Go to Rewrite Results (Not the one inside the Render settings) and paste the following Twig code:
  • {{ field_edtf_date_created|split(' to ')[0] }}
• Go back to Fields > Add > Date Created
• Go to Rewrite Results (Not the one inside the Render settings) and paste the following Twig code:
  • {{ field_edtf_date_created|split(' to ')[1] }}
• In the TimelineJS View > Format > Settings > Field mappings and ensure that the Start Date is selected as Content datasource: Date Created and the End Date is selected as Content datasource: Date Created (the Date Created field closes to the bottom of the list would be the one that was recently added and should be the one selected as the End Date)

@HyphenHook , There is similar issue: https://gundagunde.digital.utsc.utoronto.ca/collection/1/timeline

Extend the solution (from " to ") for "Until"

[HyphenHook]

Extension

• Replace {{ field_edtf_date_created|split(' to ')[0] }} in rewrite to {{ field_edtf_date_created|replace({' to ': '@', ' until ': '@'})|split('@')[0] }} (In the first date field)
• Replace {{ field_edtf_date_created|split(' to ')[1] }} in rewrite to {{ field_edtf_date_created|replace({' to ': '@', ' until ': '@'})|split('@')[1] }} (In the second date field)

Additional issues arise as more metadata with dates that are not properly formatted appear.
