Where would this bibtext go? We edit wikitext, not LaTeX documents…

I forgot to add details: the idea is to use it with Citoid, like a URL or a DOI.

So we'd paste in a bibtex citation and then it would convert it to a citation template?

That doesn't really seem like a citoid thing; a gadget maybe?

So you could have a gadget that lets you put in bibtex.

And then you could add a 'bibtex' 'maps' object into the template data to map the bibtex template (like the way we have 'citoid' 'maps' objects) to map between the bibtex parameters and the template parameters.
