ESS: A XML Standard - ESS is The Events Feed
ESS stands for Event Standard Syndication.
- ESS standard is free and open-source XML feed invented exclusively for events.
- ESS Feeds can be published from add-ons in most CMS or with simple code libraries.
- ESS federates provider’s events into one feed that can be updated everywhere in real-time.
Until now, event promoters could only use RSS or iCalendar to broadcast their events.
The problem has been that vital information gets lost in the event description.
| Event Portal | RSS Feed |

 Web readers |

Now, with ESS all the criteria of any events are clearly defined.
| Event Portal | ESS Feed |

ESS increases traffic for publishers.

ESS Libraries
ESS Feeds can be generated from open-source libraries published on: https://github.com/essfeed
You can also help the web community to create or improve these open-source libraries.
- Select an open source library and download the code in your web language.
- Place the few lines of code where you generate events.
- Each generated event is automatically submitted to the list of event aggregators defined in the library.

ESS Structure
DTD description available http://essfeed.org/history/0.9
ESS Documents are formatted in XML. ESS document are structurized with two types of XML elements :
- Simple XML elements without children to define "title", "publishing date"...
- And 8 "main XML element" that precisely describes the event.

ESS Examples
The best way to understand how a standard or a protocol works is to see a complete example in a common situation. Here is a football match event. A feed can be shorter, but this event displays the majority of the tags and features available in the ESS standard.
