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	Robots...

Now, with ESS all the criteria of any events are clearly defined.

Web readers	Robots!

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.

1. Select an open source library and download the code in your web language.
2. Place the few lines of code where you generate events.
3. 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.
