RE: "scheme" attribute of META element

Ian,

We try to use Dublin Core-compliant metadata on all of our
publicly-facing web sites, including http://www.house.gov/.  

We do not consume the data, we produce it and put it out on the web so
that others can consume.  

When it comes to creating web sites, we try to comply with the standards
published by respected sources.  The W3C recommendations are our gold
standard, but we also try to incorporate standards from other respected
sources if they are compatible with W3C recommendations.  The
recommendations of the Dublin Core Metadata Initiative
<http://www.dublincore.org/>  have traditionally fallen into that class.

We encourage compliance with these type of standards even when there are
currently few (or even no) applications that make use of particular
features - on the theory that we are contributing to creating the
critical mass of standards-compliant data on the web that will make it
worthwhile for application designers to come forward and create the
applications that can make use of the data.

Can you elaborate on this? What software do you use to actually consume 
this data? Is this internal data or is it published on the Web?

Cheers,
