Functionality

• Seems that the IRI dcat:Distribution field should be disabled?
• Let's use an autocomplete component for Format and Media Type https://alligator.io/react/react-autocomplete/
• Add error when DowloadURL is not a file link
• Add error when AccessURL value is a file link
• Add date selector on the distribution Release Date field
• The date-time widget throws an error when editing other fields, it only passes on first entry.

Styling

• fix font size
• add 'fieldsets' around nested metadata (distributions, publisher, contact)
• move distributions to the bottom, maybe add accordion

Remaining tasks:

• Submit PR on react-jsonschema-form repo for accessibility issues #324
• Create custom validator for date-time widget to allow partial dates #325

(Possible) issues

• [x] 1. Identifier field should be hidden and autogenerated on submit
• [ ] 2. When a required field is not filled out, you get a message on submit but hard to tell which field it's trying to point out
• [x] 3. When there is a schema validation error, it displays nicely at the top of the page but if you're all the way at the bottom (which you woud be, because that's where the submit button is) you can't see that anything happened; feels like the submit didn't work.
• [x] 4. Contact email field expects a "mailto:" string, should just need a regular email address
• [x] 5. In the "datasets" admin view, the edit link works but the title links to a missing page
• [ ] 6. Build files are committed to version control.. perhaps should be part of a build step that gets run during the make somehow
