Does the daemon upload the file via the filestore API? If so, I've been
working adding a uploading a dataset resource via the Ckan Python Client.
You might find it useful:

See 'add_package_resource':
https://github.com/slmnhq/ckanclient/commit/d233fcb3f73644b8b505839bedc16d3

I'm still working on adding unit tests for these changes but am awaiting
direction from the other developers.

For my use case, I'm thinking of creating a new extension based off
ckanext-datastorer. Whereas the latter converts CSV and XLS files into
JSON and puts them in ES, my plugin will convert my custom XML document
into JSON and put it in ES.

I also have this requirement but haven't made any progress towards it yet.

Yes, please. Let me know your thoughts how to go about this.
