Metadata is data describing the data structure.
Each edge of a graph carries some data. This data must be described using metadata. Metadata describes both the record as a whole and all its fields.
Records can be of different types, each field can have different data type. See Records and Fields
The metadata can be either internal, or external (shared). Metadata can also be created dynamically or read from remote sources. See Metadata Types.
For details on metadata propagation see Auto-propagated Metadata
