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

[cmungall]

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?

Betterbib now understands BibTeX, BibLaTeX, RIS, and CSL-JSON. Let's leave this open for Zotero RDF too.
