FYI, regarding the social responsibilities and expectations involved in URI ownership and use, readers may be interested in the following paper on "The URI Lifecycle in Semantic Web Architecture": http://dbooth.org/2009/lifecycle/ It is a pre-print from the Identity workshop at the upcoming Twenty-first International Joint Conference on Artificial Intelligence (IJCAI-09).
Here is the abstract: [[ Various parties are typically involved in the creation and use of a URI, including the URI owner, an RDF statement author, and a consumer of that RDF statement. What principles should these parties follow, to ensure that a consistent resource identity is established and (to the extent possible) maintained throughout that URI's lifetime? This paper proposes a set of roles and responsibilities for establishing and determining a URI's resource identity through its lifecycle. ]] Comments and suggestions are invited, of course.
