PUBLIC MARKS with tags semantic & metadata

Common Tag is an open tagging format developed to make content more connected, discoverable and engaging.

With Common Tag, site owners can more easily create topic hubs, cross-promote their content, and enrich their pages with free data, images and widgets.
