Ecco una realizzazione delle potenzialità del Web 2.0: il collaborative tagging.
Collaborative tagging is regarded as democratic folksonomy metadata generation, i.e. rather than an individual controlling the metadata or tags about an article or other content, metadata is generated by both the creator and consumers of the content.

In pratica, l’utente viene chiamato a indicizzare un contenuto: questa tassonomia generata “dal basso”, ovvero da chi legge, si chiama folksonomy.
A folksonomy is a user generated taxonomy used to categorize and retrieve Web pages, photographs, Web links and other web content using open ended labels called tags. Typically, folksonomies are Internet-based, but their use may occur in other contexts as well. The process of folksonomic tagging is intended to make a body of information increasingly easier to search, discover, and navigate over time. A well-developed folksonomy is ideally accessible as a shared vocabulary that is both originated by, and familiar to its primary users.
