Why a Feeds Profile

The ZedAI Feeds Profile is a light-weight profile specifically designed to encapsulate and represent the semantics inherent in electronic feeds e.g. RSS, ATOM, NewsML, NITF ...

In deciding on whether an explicit Feeds Profile was necessary, given that a richer Periodicals Profile that would be capable of representing concepts from both printed newspapers and magazines was also being worked on, the working group had to consider the following variables:

• How onerous would it be for Newspaper and Magazine vendors to supply a publication in the Periodicals Profile.
• Are the semantic requirements of electronic feeds distinct enough from their printed counterparts to warrant a separate light-weight profile.

What contexts has the Feeds Profile been designed to address?

The ZedAI Feeds Profile has been designed to address the following contexts:

• Newspaper and Magazine vendors wanting to supply an entire publication in a light-weight XML grammar.
• Newspaper and Magazine vendors wanting to supply a single article, or a collection of articles from a publication in a light-weight XML grammar.
• Newspaper and Magazine vendors wanting to supply a single article, or a collection of articles from different publications in a light-weight XML grammar.
• Organisations wanting to convert all their incoming electronic feeds into a light-weight XML grammar.
• Organisations wanting to aggregate individual articles into one or more publications using a light-weight XML grammar.

Metadata requirements

to address the requirements of all the contexts listed above, the feeds profile defines the following metadata:
