Add related and relatedtype fields to BibLaTeX exports

[alexreg]

What is the correct way to add the related and similar fields to biblatex exports? See section 3.5 of the biblatex manual. For example, output like the following.

@Book{key1,
  ...
  related     = {key2},
  relatedtype = {reprintof},
  ...
}
@Book{key2,
  ...
}

It looks like the following content in the Extra field of a Zotero entry would work, but I'm not sure it's the ideal solution.

biblatex.related: key2
biblatex.relatedtype: reprintof

That is indeed the solution. I don't know of any Zotero information that could be used to generate these otherwise; Zotero knows generic relations but they are untyped.

Thanks for the authoritative response. Yes, I'd come to the same conclusion about Zotero's concept of relations.
