Many web-based public repositories are widely adopting tag-based metadata approaches as their main classification mechanism. This phenomenon is fostering initiatives to improve the semantic interpretation of tags, usually involving two main entities: "social ontologies", which emerges from the collaborative tagging (folksonomies), and formal ontologies. In order to analyze and compare these initiatives we present here an abstract framework. It supports our argument that existing approaches do not explore the full potential of the combination between folksonomies and ontologies due to their unidirectionality. The framework is also the basis to evidence that a fusion approach---as proposed in our "folksonomized ontology"---enables to better explore the organic semantics of folksonomies combined to the engineered semantics of ontologies.
