RSS (RDF Site Summary or Really Simple Syndication) is a method of describing news or other Web content that is available for "feeding" (distribution or syndication) from an online publisher to other websites. RSS is an application of the Extensible Markup Language (XML) that adheres to the World Wide Web Consortium's Resource Description Framework (RDF).
As a professional developer, you may want to "publish" news headlines, stories, or information from your Website in the form of an RSS document.
RSS files are a type of metadata. Metadata are:
- units of information about information.
- used to provide descriptive information about the content, context, and characteristics of data.
An RSS file commonly contains four main types of elements: channel, image, items, and text input. News is only one form of content that can be distributed with an RSS feed. Other possibilities include discussion forum excerpts, software announcements, and any form of content retrievable with a URL.
