Next week starts the Knowledge Construction Challenge from the CKC2007, a Workshop on Social and Collaborative Construction of Structured Knowledge which is arranged in conjunction with the 16th International World Wide Web Conference (WWW2007) in Banff, Canada.
The goal of the CKC challenge is to use the current state of the art for the tools as a jumping off point to collect and discuss requirements for such tools; features that users need; features that they like or dislike.
OntoWiki is one of the participating tools and we invite you to participate in the challenge.
