Add 'Download All' option for multi-file Works

[chrisdaaz]

Descriptive summary

Relates to Hyrax 1.x

Rationale

Users may want to download all of the files in a Work with one click, such as this example of MATLAB scripts and formatted data.

Story: Reader reads an article that lists the DOI of the article's supporting data set. Reader visits the data set in the institutional repository, represented as a Work. The Work contains X number of files. Reader wants to download a local copy of the data set.

Expected behavior

Here's an example from Figshare:

Here's an example from a journal:

Actual behavior

Download each file individually.

There's the question of nested works. I'm not sure I understand nested works (chapters within a book?) and how they might relate to files within a work. My hunch is to limit this feature to downloading all the files within a single works.

[escowles]

I agree that this feature would be useful even if it was limited to the files in a single work.

I think some nested works might be better if this feature was recursive. For example, we have MultiVolumeWorks, which bundle multiple ScannedResources, where each ScannedResource is a volume in a multi-volume book set. Being able to download the entire set in a single zip file would be better, but being able to download each volume as a zip file would be better than nothing.

We added this to our repository. You can take a look at the way it works here:

There was an initial PR for this and then two others to fix some bugs/changes:

Good functionality to add. "Download All Files" as shown on DeepBlue.lib.umich.edu is simple and intuitive.

I agree that even if it does not extend to child works that it is a feature worth adding.

Is it out of scope to provide the metadata of the work as a csv (or xml) included in the zip? That metadata may contain important rights information as well as identify the works. The feature would also then apply to works with a single file attached.

:+1: to download all files + metadata!

Re-upping as important to repo-managers!
