GD Rating System Pro is still in development. This is the first beta version with all core features and most of the addons completed.
GD Rating System Pro 1.0 Beta #1 brings new rating method called Thumbs Rating and addon for Rich Snippets. Thumbs Rating is fully functional, and the final version of the plugin will include some more styles to choose from. Rich Snippets addon uses microdata to allow search engines (Google) to get ratings. It is based on Scheme.org specifications. One of the future versions will bring support for JSON-LD format.
One feature still missing is the Editor addon allowing you to edit the votes and ratings from the admin side. This will be ready for the Release Candidate version to be released on Monday. Final version for both Pro and Free plugin will be released on Wednesday. I am preparing several videos about setting the plugin, and all the plugin features, and they will be ready by Wednesday too.
