Markdown Database Pattern

Since this presupposes Markdown of the flavor that comes with YAML frontmatter, and that frontmatter is doing all of the heavy lifting, this is more like a YAML database than a "Markdown database".

In any case, nowhere is it indicated why this approach (no matter what you call it) should be preferred over e.g. recfiles.

I've recently switched to SilverBullet[1] as my day-to-day note taking and task tracking app, because of it's very powerful ability to embed little queries and scripts directly in a page to build lists/tables/links that based on data from other pages. This looks like an interesting way to leverage markdown libraries in different ways. Nice!
