XHTML Meta Data Profiles (XMDP) is a format for defining metadata 'profiles' or formats in a machine-readable fashion, while also enabling people to see a description of the definition visually in a web browser. XMDP definitions are expressed in XHTML (or possibly HTML). Examples of applications that use XMDP include XFN and hCard.
Example
<dl class="profile"> <dt id="title">title</dt> <dd>The name given to a piece of work.</dd></dl>To apply, use the profile attribute in the head element of your document:
<head profile="URL">Where URL denotes the full address of your XMDP profile resource.
