Abstract
This paper describes some ideas for a secure survivable semantic web that follows some of our previous ideas on dependable semantic web. Semantic web is a technology for understanding web pages. It is important that the semantic web is secure. In addition, data exchanged by the web has to be of high quality and survive failures and errors. The processes that the web supports have to meet certain timing constraints. This paper discusses these aspects, and describes how they provide a dependable semantic web.
