Alerting Standards
The section covers alerting standards including RSS, Atom and OPML.
RSS
Standard: RSS is a widely used standard for news feeds and content syndication.
About the Standard: RSS provides a simple mechanism by which news can be described and made available. RSS alerts can be easily embedded in Web pages, aggregated by RSS aggregation tools, viewed in dedicated RSS readers, etc.
Version: Confusingly the term 'RSS' covers two separate formats. In RSS 1.0 the term standards for RDF Site Summary whereas in 'RSS 2.0' (which is a different, and not later, version to RSS 1.0) RSS standards for Really Simple Syndication.
Maturity: RSS is widely used, is simple to create and is a very powerful technology.
Risk Assessment: The competing approaches and confusion in the terminology can result in an inappropriate version of RSS being used. At present RSS readers can normally process both versions, but this may not be the case in future.
SOA Role: Alerting.

Update History:
OPML
Standard: OPML (Outline Processor Markup Language).
About the Standard: OPML (Outline Processor Markup Language) is a format which can be used for managing groups of RSS feeds.
Version: Not known
Maturity: RSS appears to be the main mechanism used for importing and exporting RSS feeds between RSS readers.
Risk Assessment: OPML was developed by Davey Winer. The format has not been adopted by a formal open standards body. However, in practice, developers of RSS tools appear to have accepted OPML as an industry standard.
SOA Role: Alerting.
