nesta-plugin-yaml-metadata

Pages of content in Nesta CMS can be embellished with metadata, written in a simple key/value pair syntax. If you'd like extra flexibility in your metadata, you can use this plugin to replace Nesta's built-in metadata parser with Ruby's Yaml parser. You still need to make sure that all the metadata is at the top of the page; the first blank line signifies the start of the page content.
