event is in its nature a multimedia event. News try to capture
information about the events into various data formats to make
it suitable for delivery to the recipients. But, as the number
of information sources constantly grows, recipients are overflooded
with the information. At the same time, they lack the ability
to select relevant information without having to actually process
all the information they receive.
The paper presents how XML can utlilize metadata to describe content
and structure of the data it carries.
It shows how NewsML, an XML based standard for news exchange,
uses metadata to enable content filtering, version handling, correction
management, choosing between multiple data formats and other features
is paid to the XML features and XML-related standards that enable
such a behavior and to the reasons why some techniques have or
have not been used by the standard.
In conclusion, it is shown how NewsML interacts with other relevant
standards and discussed whether it can be used outside the news
environment as a general-purpose data wrapper.
