From the Metaweb to the Semantic Web: A Roadmap "At Radar Networks we have been working to define this ontology -- which we call "The Infoworker Ontology" -- with a goal of evententually contributing it to a standards body in the future. The Infoworker Ontology is a mid-level horizontal ontology that defines the semantics of common entities and relationships in the domain of knowledge work -- things like documents, events, projects, tasks, people, groups, etc. The development and adoption of an open, extensible, and widely-used Infoworker ontology is a necessary step towards making the Semantic Web useful to ordinary mortals (as opposed to academic researchers).
By connecting microcontent objects to the Infoworker Ontology a new generation of semantic-microcontent (what we call "metacontent") is enabled. With the right tools even non-technical consumers will be able to author and use metacontent. "
