URI lifecycle (Was: Owning URIs)

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.
