Resource author is always "unknown"

When you create a dataset can can enter an author for the dataset and it'll be shown on the dataset's page. But if you add a resource to that dataset and then go to the resource's page, it'll say author unknown.

I'm not sure whether this field is supposed to show the dataset's author or if resources have their own authors (when you create or edit a resource, there's no author field to fill in), either way this is a bug.
