The Z39.98-2012 Newsfeed Aggregator Profile is intended to serve as an XML republishing format for syndicated web content, primarily news.
The profile intends to capture input sources served in formats such as NewsML, Atom, NITF and RSS in a single format, using markup that is economic to produce but still rich enough to allow transformation to various accessible formats (such as Braille, DAISY and large print).
The profile is designed to address the following usage contexts:
The profile allows the expression of document-wide as well as article-level metadata. A set of terms has been defined to allow the metadata to describe both properties of the source material as well as the intended output.
Although the profile is primarily intended to be used in automated aggregation and republishing contexts, it does not exclude use in manual authoring environments.
This profile is maintained by the ANSI/NISO Z39.98 advisory committee under the auspices of NISO.
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this section are to be interpreted as described in RFC2119.
