User Story

In order to determine the type of resource or download a dataset offers, datagov wants to add functionality to determine mimetypes of distribution URLs.

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• GIVEN a dcatus distribution
  AND a "downloadURL" for that distribution
  WHEN the function is called
  THEN the mimetype is determined

Background

• navigate to the downloads & resources portion of a dataset page. the mimetype ("format" in ckan) determines what's displayed in the UI ( e.g. a resource is a .csv file so the icon is a csv doc and the button allows the user to download that doc )

[Any helpful contextual notes or links to artifacts/evidence, if needed]

Security Considerations (required)

[Any security concerns that might be implicated in the change. "None" is OK, just be explicit here!]

Sketch

• implement guess_resource_format passing the distributionURL.
• using that as input, get the final resource type via resource mapping.
• all of this could happen in the DCATUS-to-CKAN transformation.
