Add option to work with other formats (.ris, zotero rdf)

I have been using .bib format on and off for decades, it's a terrible format. Every single bibliographic management system seems to mess it up in different ways. For example, when I do a paperpile export to .bib it loses the URL, and I assume the URL is a crucial piece of metadata to allow betterbib to do its work.

Are there any plans to work with any formats that are more sane and less lossy?
