public interface Snak

Snaks are the basic information structures used to describe Entities in Wikibase. They are an integral part of each Statement (which can be viewed as collection of Snaks about an Entity, together with a list of references).

The most basic (and most common) form of Snaks are property-value pairs, but other forms exist.
