Who owns subscription data?. As Bloglines
continues to grow, its subscription data becomes more interesting.
Yesterday, while demonstrating the application to some folks, I showed
how you can navigate from a feed to the list of subscribers
to that feed. Only those subscribers who agree to make their data
public are shown. So in my case, for example, there are only 755 public
subscribers out of 2337 total subscribers. But that's more than enough
transparency to do some useful data mining. ... [Jon's Radio]

The Handle System. A comment
in my discussion area yesterday noted that, for
the Koper link, "they actually use the Handle system
and state explicitly to point instead to http://hdl.handle.net/1820/238"
(or hdl:1820/238,
though most browsers don't support that notation). The idea
of the handle system is that, instead of pointing directly
to a link, you point to a handle proxy server, which will
redirect you to the link. This is exactly how Persistent
Url (or Purl)
works, except without the special handle syntax. The
benefit is that if the URL for the resource changes, links
using Handle still work (assuming that someone remembers to
update the Handle proxy server). On the other hand, as the
Handle documentation states, the system is perfect for
managing Intellectual property - that is, it is
perfect for enforcing access restrictions at the network
level, rather than at the server or resource level. Maybe
so - but this was the point of my discussion with Dan
Rehak in Utah over CORDRA,
which also uses the Handle system. Applying digital rights
at the network level, in addition to imposing a substantial
overhead on everybody, runs the risk of fracturing the
internet into a series of private networks. Will CORDRA or
Handle do that? I don't know. I have no doubt that some
people would like it to, though, and so urge caution
regarding the implementation of Handle. The Handle system
is used now by Digital Object
Identifier (DOI), Defense Virtual
Library, and DSpace,
among others. By Various Authors, October 22, 2004

Metadata for the Masses. Nice brief discussion of the idea of
ethnoclassification - classifications systems evolving
through undirected use by a population, rather than
stipulated from above by a standards body. The path analogy
is especially apt. By Peter Merholz, Adaptive Path,

Describe This. According to the announcement, Describe This is
"a service designed for the automatic extraction of
metadata from online resources. The site offers an easy to
use interface where you can indicate the resource to
analyze and how to download the results as XML, XHTML or
RDF files." I tested it on my own website and on David
Merrill's PDF (see below) and it worked for both, though
certain desirable metadata (such as DC:creator) were
missing. It can automatically analyze and generate metadata
registers for the following formats: HTML and XHTML, Dublin
Core/RDF, Dublin Core/XML, Dublin Core/HTML (META tags),
GIF, JPG (EXIF) and other image formats, RSS, bibTex and
some proprietary Formats XML, for example Amazon XML Web
Services. Thanks, Toni, for the link. By Various Authors,
