com.evernote.edam.type.Data
In several places, EDAM exchanges blocks of bytes of data for a component which may be relatively large. For example: the contents of a clipped HTML note, the bytes of an embedded image, or the recognition XML for a large image. This structure is used in the protocol to represent any of those large blocks of data when they are transmitted or when they are only referenced their metadata.

bodyHash

This field carries a one-way hash of the contents of the data body, in binary form. The hash function is MD5
Length: EDAM_HASH_LEN (exactly)

size

The length, in bytes, of the data body.

body

This field is set to contain the binary contents of the data whenever the resource is being transferred. If only metadata is being exchanged, this field will be empty. For example, a client could notify the service about the change to an attribute for a resource without transmitting the binary resource contents.
