File Upload Widget

[dharizza]

User Story

As a data publisher, I want to be able to upload files through a user interface, so that I can share my data without having to use a remote file.

Acceptance Criteria

(add once we decide if we're using data.gov's UI)

Implementation details:

Create custom widget that allows users to choose what they want to add (either a URL or file).

• widget should be a field chooser with two tabs:
  • one for URL
  • one for file upload
• add validations:
  • If user chooses url —> we should validate if it is a valid url.
  • If user chooses a file upload —> we should validate if the resulting URI corresponds to an existing file.
• both fields will return an URI, which is what will be saved in the JSON Metadata field
