A friendly front door to RO-Crate collections
Research archives like PARADISEC hold thousands of digitised recordings of endangered languages and cultures. The Collection Downloader gives people a simple way to explore that material — without needing to understand the API behind it.
It reads collections from any RO-Crate API, lets you drill down from collections to items to individual files, and hands you a tidy zip of just the files you chose — delivered as a download link by email.
