module Text.Atom.Feed.Link

-- | Atom feeds uses typed IRI links to represent information / metadata
--   that is of interest to the consumers (software, in the main) of feeds.
--   For instance, the edit link relation attached to an atom:entry element
--   points to the IRI to use to update/edit it.
--   
--   The Atom standard encourages that such typed links to be registered
--   with IANA if they have wider applicability, and the
--   <a>LinkRelation</a> data type encodes the currently registered link
--   types (derived from:
--   http://www.iana.org/assignments/link-relations.html on 2007-10-28]
