FrameBase is a schema that allows representing a wide range of general knowledge in a knowledge graph. It is a schema in the RDFS, but it can also be adapted to other kinds of databases or structured data. The purpose of FrameBase is allowing knowledge to be represented, shared and combined in a homogeneous way, providing a sort of "common vocabulary for common knowledge".

FrameBase offers several levels of knowledge representation: the "reified" level representing situations and events as explicit entities, and the "dereified" level, using binary predicates to connect directly the properties of these situations or events.

Currently, FrameBase entities only have annotations in English, but it may be extended in the future.
