Some definitions • Weblog • A web site (usu. of personal/non-commercial origin) that is frequently updated with information and links to resources within a particular subject. The published information is presented much like a journal on the web in reverse chronological order. • News feed • A data file listing recent entries from a weblog. • A data file listing recent news headlines from a commercial source. • Feed formats are in XML format (specifically RSS or RDF). • News aggregator • An application that retrieves and displays news feeds from multiple sources. • Client application -- runs on PC for individual use. • Server application – runs on a web server for group use.
