Fix Duplicate File Format Labels in Resource Cards

[SueValente]

User Story

In order to understand what file formats are available for a dataset, users want to see each format listed once (not repeated multiple times like "html html html html").

Acceptance Criteria

• GIVEN a dataset has resources in the same file format
  WHEN a user views the resource cards
  THEN each unique format slug appears only once per resource

• GIVEN multiple resources exist for a dataset
  WHEN viewing the resources section
  THEN the format labels are clear and meaningful to public data users

Background

Source: External beta feedback from Chris Marcum (christopher.steven.marcum@gmail.com) - 1/26/2026

Current problem:

• File format slugs are being repeated in resource cards (e.g., "html html html html")
• This repetition doesn't make sense to public data users out of context
• Format labels should be clear and appear once per resource

Example: A dataset with multiple HTML resources shows "html" repeated multiple times instead of showing it once or providing more context

Security Considerations

None - UI display bug fix with no security implications.

Sketch

• Identify where file format slugs are being rendered in resource cards
• Debug why formats are being repeated
• Fix rendering logic to display each format once per resource
• Consider whether format labels need additional context (e.g., "HTML - Interactive Map" vs just "html html html")
• Test with various datasets that have multiple resources of the same type
• Verify fix works for all file format types (HTML, PDF, CSV, API, etc.)
