As an SDA operator, I want to list all the files referenced by the metadata so that we can ingest the right files

[viklund]

Describe the user story

To be able to start the ingestion process for the data files we need to know what files to ingest. The metadata-submitter has this information in the metadata.

There are probably several "file types" that could be referenced by the metadata, but we start with the most important filetype for bigpicture which is the image. Here is an example of a file reference in the image XML.

Tasks:

• Implement an API endpoint that probably queries the mongodb for all the files and then return them in some json structure (this should include the checksums).
• Check with the bigpicture metadata group if there are more places than in the image XML where files can be referenced.

Testing

I don't know what your practice is, please fill this in.

Definition of Done

Given this metadata uploaded to a submission when I call this new API then I expect json response with the metadata about that file.
