Dublin Core tags in mp's HTML output

This note is intended to explain how mp maps FGDC CSDGM elements to Dublin Core elements in the META tags of the HEAD section of its HTML output. If you are in doubt about what is explained here, the best information is always going to be found in the source code of mp, in the file html.c at this writing.

The Dublin Core tags are identified using a LINK tag in the HEAD element, placed before the META elements containing the element values. The LINK tag is written as follows:

<link rel=schema.dc href="http://purl.org/metadata/dublin_core">

Other META tags are written in the following form:

<meta name="dc.element" content="stuff">
where element is replaced with the Dublin Core element name and stuff is replaced with the element's value as indicated below.
