Naming Convention

A naming convention is the enforced rule set for writing event names and property keys, covering casing, separators, word order and reserved prefixes.

Most event stores are case sensitive, so ArticleViewed and article_viewed become two separate entities whose counts never merge. A common pattern puts the object before the action so that every event about one subject sorts together in lists and filters. The convention only works when it is applied at the moment an event is defined; without validation at that point, a few months produce several parallel names for one concept, and renaming them later does not repair the history. A convention is also not a taxonomy: the convention says how a name is written, the taxonomy says which family that name belongs to.
