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

The most consistent form of metadata that I've found for Markdown is actually HTML meta tags, since most Markdown interpreters recognize HTML tags and will not render meta tags, meaning that metadata can be stored in a way that will not show up in rendered HTML.

## Heading
Markdown content begins here

You can try this in something like GitHub Gist or StackEdit.
