💥 Proposal

We have a collection of Markdown articles that we want to use a) as a data source for a Docusaurus site and b) as a data source for Pandoc to generate pdfs from them via Latex (these will be printed out and used in schools and universities).

Pandoc expects multiple authors to be listed in the frontmatter "author" field, while Docusaurus expects them to be listed in the "authors" field. It would be great if the blog plugin would either also accept multiple authors in the "author" field or (even better) offer a method to provide a custom metadata provider that can override the default behaviour of the blog plugin and create the blog metadata from the Markdown frontmatter. Maybe this is already possible, but I could not find a way in the docs or by taking a quick look at the source code.

Keeping Markdown source files for blog articles decoupled from any specific publishing pipeline does make sense in general and such a customization option in Docusaurus would make it much easier to do so.
