I would like to announce the launch of the Metacentric news feed and
metadata service at:
http://www.metacentric.net/
The Metacentric site is designed to be as clear and simple as
possible to use, with jargon kept to an absolute minimum. The site
includes FAQs and illustrations others might find useful to explain
news feeds and metadata to a general audience. The notes below are
intended for specialist interest on the DC lists.
Metacentric provides a scraper service that transforms standard HTML
into RSS 1.0 using XSL transformation. It also processes any Dublin
Core metadata in the source according to the DC in HTML
recommendation [1]. The Metacentric service also includes a pure RDF
metadata feed option for Dublin Core metadata, see the test cases
below.

(Examples redirect to Metacentric)
HTML input is passed through JTidy [2] to convert to XHTML, and is
validated against a "lax" DTD, so the system tolerates a range of non-
standard markup. All processing is conducted remotely, so requires no
scripts, databases or special software on source Web sites.
The system caches the transformation result according to any HTTP
expires header for the source HTML, or for one day if none is
present. Customers can force a refresh for urgent changes through the
Metacentric Web site.
Thanks to those on the DC-ARCHITECTURE list who helped with technical
issues over the past few years, especially Chris Croome.
Best regards,
Phil
