Folders in datasets

[laurenwalker]

Add support to the dataset editor for adding folders and organizing files into folders, which uses the prov:atLocation work that Tommy has implemented in Metacat.

I'm creating this issue as an Epic (in Zenhub) since there are many ways this should be supported:

• [x] Design mockups (Issue #1454)
• [x] Show folder structure in MetadataView (issue #1452)
• [ ] Show folder structure in dataset editor (issue #1452)
• [ ] Allow editing of folder structure in dataset editor (issue #1453)
• [x] Use the DataPackageView in the MetadataView to display the package instead of the PackageTableView. Then we only have to add support to a single view. (The DataPackageView has a better design anyway). (issue #1452)

Background

• Some data packages make use of a file system structure to organize and present data objects, but currently in MetacatUI, all data objects can only be displayed and uploaded in a flat structure, like so:

Display view

Editing view

• DataONE resource maps now make use of a atLocation property that indicates the location of files in a data package relative to others.
• Metacat supports this feature already, in that when you download a package with atLocation information in the resource map, the folder structure is preserved in the downloaded zip.
• We would like the display and editing of packages in MetacatUI to reflect the atLocation feature.

Examples

• The published data package doi:10.18739/A2NK36626 includes atLocation information in the resource map (resource_map_doi:10.18739/A2NK36626)
• A private data package urn:uuid:028b8008-8b68-491a-8a13-79b642e1e215 with atLocation information in the resource map (resource_map_urn:uuid:028b8008-8b68-491a-8a13-79b642e1e215)
• Tommy's repository of test datasets with atLocation information (search for atLocation in the repo)
