Markdown metadata format

Question

Is there a standard or convention for embedding metadata in a Markdown formatted post, such as the publication date or post author for conditional rendering by the renderer?

Answer 1

This is not a standard way, but works with Markdown Extra.

I wanted something that worked in the parser, but also didn't leave any clutter when I browse the files on Bitbucket where I store the files.

So I use Abbreviations from the Markdown Extra syntax.

*[blog-date]: 2018-04-27
*[blog-tags]: foo,bar

then I parse them with regexp:

 ^\*\[blog-date\]:\s*(.+)\s*$

As long as I don't write the exact keywords in the text, they leave no trace. So use some prefix obscure enough to hide them.
