About RSS
RSS is an XML based document format for syndicating news and other
timely news-like information. It provides headlines, URLs to the
source document and brief description information in an easy to understand
and use format. RSS based "News Readers" and "News Aggregators" allow
the display of RSS headlines on workstation desktops. Software libraries
exist to read the RSS format and present RSS headlines on webpages
and other online applications.
These NWS supplied RSS documents use the RSS 2.0 format. Each
RSS item links to the html/web documents described above. Additional
