Several communities have engaged recently in assembling a Body of Knowledge (BOK) to organize the discipline knowledge for learning and sharing. BOK ideally represents the domain, contextualizes assets (e.g. literature), and exploits the Social Web potential to maintain and improve it. Semantic wikis are excellent tools to handle domain (ontological) representations, to relate items, and to enable collaboration. Unfortunately, creating a whole BOK (structure, content and relations) from scratch may fall prey to the "white page syndrome"1, given the size and complexity of the domain information. This article presents an approach to jump-start a BOK, by implementing it as a semantic wiki organized around a domain ontology. Domain representation (structure and content) are initialized by automatically creating wiki pages for each ontology concept and digital asset; the ontology itself is semi-automatically built using natural language processing (NLP) techniques. Contextualization is initialized by automatically linking concept- and asset-pages. The proposal's feasibility is shown with a prototype for a Software Architecture BOK, built from 1,000 articles indexed by a well-known scientific digital library and completed by volunteers. The proposed approach separates the issues of domain representation, resources contextualization, and social elaboration, allowing communities to try on alternate solutions for each issue.
