The principal XML element that characterizes an ESS event is the category under which that event is labeled.
The category defines the theme of an event and the purpose of this section is to universalize all main stream events into general categories.
ESS event categories are essential- they create a virtual connection between all events that use ESS as a standard.
ESS categories start from generic main-stream theme definition and uncover more specific definitions. Each category has a specific unique identifier, this ID simplify ESS Processors feeds analysis to cross similarities with other events.
A Basketball match can be defined by: Sport (C) > Team Sport (C2) > Basketball) The ESS category ID for such an event is C2 with in keywork and description Basketball.
A cinema listing can be defined as: Cinema > Action Movie The ESS category ID for such an event is I3 (worldwide and permanent).
At the same time, a portal that federates ESS event feeds can easily display the kinds of events that interest readers (A25B). Humans are not needed to retrieve the information and post it: the source creates the feed, the subscriber syndicates to the feed and with the category ID can receive updated and relevant information regarding events and happening that fall under that category.
ESS documents are composed by various main XML elements. ESS processors must consider each and every element's description as valid and applicable to each and every other XML element within the same ESS document. If this is not the case, then it is the responsibility of another
