  As a developer
  I want utility functions to work correctly
  So that dataset processing is reliable

  Scenario: Map valid HuggingFace license
    When I map license "MIT"
    Then the license should be "mit"

  Scenario: Map unknown license to other
    When I map license "Custom License"
    Then the license should be "other"

  Scenario: Map None license to other
    When I map license None
    Then the license should be "other"

  Scenario: Get size category for tiny dataset
    When I get size category for 0.005 GB
    Then the size category should be "n<1K"

  Scenario: Get size category for small dataset
    When I get size category for 0.5 GB
    Then the size category should be "1K<n<10K"

  Scenario: Get size category for medium dataset
    When I get size category for 5 GB
    Then the size category should be "10K<n<100K"

  Scenario: Get size category for large dataset
    When I get size category for 50 GB
    Then the size category should be "100K<n<1M"

  Scenario: Get size category for xlarge dataset
    When I get size category for 500 GB
    Then the size category should be "1M<n<10M"

  Scenario: Get RDF format for turtle
    When I get RDF format for "turtle"
    Then the format should be "turtle"

  Scenario: Get RDF format for RDF/XML
    When I get RDF format for "rdf/xml"
    Then the format should be "xml"

  Scenario: Get RDF format for N-Triples
    When I get RDF format for "nt"
    Then the format should be "nt"

  Scenario: Get RDF format for unknown format
    When I get RDF format for "unknown"
    Then the format should be "turtle"

  Scenario: Get dataset info for valid dataset
    When I get dataset info for "wordnet"
    Then the dataset info should be returned

  Scenario: Get dataset info for invalid dataset
    When I get dataset info for "invalid-dataset-xyz"
    Then the dataset info should be None

  Scenario: Create dataset card
    When I create dataset card for "wordnet"
    Then the card should contain dataset name
    And the card should contain license information
    And the card should contain format documentation

  Scenario: Get most recent file in directory
    Given a directory with multiple files
    When I get the most recent file
    Then the newest file should be returned

  Scenario: Get most recent file in empty directory
    Given an empty directory
    When I get the most recent file
    Then None should be returned

  Scenario: Get RDF format documentation
    When I get format documentation for "wordnet"
    Then the documentation should contain schema information
    And the documentation should contain example code
