Abstract : In this paper, we highlight how semantic wikis can be relevant solutions for building cooperative data driven applications in domains characterized by a rapid evolution of knowledge. We will point out the semantic capabilities of annotated databases and structured wikis to provide better quality of content, to support complex queries and finally to carry on different type of users. Then we compare database application development with wiki for domains that encompass evolving knowledge. We detail the architecture of WikiBridge, a semantic wiki, which integrates templates forms and allows complex annotations as well as consistency checking. We describe the archaeological CARE project, and explain the conceptual modeling approach. A specific section is dedicated to ontology design, which is the compulsory foundational knowledge for the application. We finally report related works of the semantic wiki use for archaeological projects.
