The core mission of the semantic web, namely, to enable information to be shared across the web, faces significant challenges. The challenges come from the difficulty of capturing semantics in a manner that is reusable across applications, the priority of process over data, the importance of interaction, and the critical need for accommodating user context. Overcoming these challenges takes us from the realm of semantics and brings us into the realm of pragmatics, which we view as supervenient upon the semantics. We claim that when the vision of the semantic web is realized, it will be via the pragmatic web.
