Arguments

x	an object for which the metadata will be read or set
field	metadata field name(s); if NULL (default), return all metadata names
type	"user" for user-provided corpus-level metadata; "system" for metadata set automatically when the corpus is created; or "all" for all metadata.
value	new value of the metadata field

Value
