AFAIK, mds is the metadata schema daemon which generates the data for Spotlight. See <http://developer.apple.com/documentation/Carbon/Reference/MDSchemaRef/index.html> and <http://developer.apple.com/documentation/Carbon/Conceptual/MetadataIntro/index.html?http://developer.apple.com/documentation/Carbon/Conceptual/MetadataIntro/Concepts/SpotlightAttrs.html> for details. It and mdimport are what Spotlight use to collect and display metadata.
