Express both the identifier and location of remote content
When a news provider sends a newsItem to its customers with remote content (using a <remoteContent> tag), he often has the practical need to indicate the relative URL where the associated newsItem content can be retrieved (often a simple file name). But the provider’s information system stores content in a DAM, where it is identified in a unique way: therefore a global identifier is also needed on the tag, which may be suppressed before the newsItem is distributed. Currently remoteContent/@href plays both roles.
a) To create a consistent set of attributes on remoteContent, link, itemRef and icon:
@href (URL), @residref (string), @version (positive integer), @contenttype (string), @format (qcode) and @size (non negative integer).
b) To deprecate the use of @guidref in link and @remoteContent and to deprecate the use of @hreftype in link and itemRef. @guidref and @hreftype are still defined in the specification and schema, but it is specified that these attributes should not be used any more.
Example1 (in newsItem/itemMeta): <link residref=”tag:afp.com,2008:target1” version=”2” href=”./target1.xml” contenttype=” application/vnd.iptc.g2.newsitem+xml” size=”1024”/>
Which means that the target of the item link is the newsItem having “tag:afp.com,2008:target1” as guid, in version 2, retrievable from “./target1.xml”, which size is 1024 bytes.
Example2 (in newsItem/contentSet): <remoteContent residref=”PAR2342342” href=”./target1.jpg” contenttype=”image/jpeg” size=”1002400”/>
Which means that the remote content is the JPEG image having “PAR2342342” as system id, retrievable from “./target1.jpg”, which size is 1002400 bytes.
