Inktomi Search Solution (formerly Ultraseek search engine) offers tuning for Dublin Core tags to increase their relevance ranking. In addition, it can use DC.subject for its rule-based Content Classification Engine (hierarchical topic categories). You can set up advanced search queries to work with DC tags. Check out our Bridges site for more information and studies on this (http://bridges.state.mn.us) and the State of Minnesota's search site for an implementation of the Content Classification Engine (http://search.state.mn.us). I would be happy to correspond privately about your other questions.

I've only recently joined this list and I still have a lot to learn about
metadata in general and Dublin Core specifically but I'd like to ask an
early question if I may.
The content management system we use to store our curriculum web pages
creates DC tags in the HTML page header thus
<meta name="DC.Contributor" content="David Davies">
<meta name="DC.Format" content="text/html">
<meta name="DC.Language" content="en">
Do internet search engines such a Google use these tags in a meaningful way
or is the text contained in the content attribute just lumped in with the
text of the page itself to improve the chance of a 'hit' when a user submits
More specifically, I would like to know if anyone knows of a search engine
that can explicitly make use of these tags by allowing a complex search
query? Say I have a multilingual site and I want to pull out pages where
DC.Language" = "en". I'd need to be able to construct a search query that
allowed input of one or more DC meta tags as qualifiers. Anyone any ideas if
there's a search engine that does this?
Our content management system allows the user to search based upon the
values of DC meta tags as well as free text in the body of the page but I
would like to use a search engine that indexes a number of sites yet still
retains this functionality. And by number of site I mean hundreds or
thousands, the kind of order of magnitude that makes Google an useful
Is this a case of off the shelf or do it yourself?
