What portlets, Add-ons, etc... were used to create vaadin.com/directory

I’m looking to build an internal Liferay 6EE-based site somewhat similar to http://vaadin.com/directory (an internal listing of source-code, libraries, toolkits, etc… developed at our company to help others that may be working toward similar software goals find each other and leverage their prior work - with ratings, comments, discussion, etc…).

I’m hoping somebody can point out some of the portlets, add-ons, etc… that were used to create the Vaadin add-ons directory.


Directory portlet is a custom application fully implemented in Vaadin. Some of the add-ons it includes are CustomField and RatingStars.
