This document discusses using semantic wikis to reduce the steep learning curve in developing semantic web applications. It presents a semantic wiki called Towards Social Webtops that allows for easy publishing, smart data propagation, fast prototyping in the browser, and lightweight concept modeling. The semantic wiki is demonstrated at http://tw.rpi.edu/wiki and includes applications like an RPI map and events calendar, a wine wiki, group information management, and an ontology repository. It addresses challenges in data organization, sharing, personalization, privacy, and provenance through features like RDF modeling, relational modeling, rules, semantic templates and forms, annotation extensions, and remote querying of multiple wikis.
