mdex:boolean | 
Represents a Boolean value (TRUE or FALSE). Used for atomic values (from single-assign Boolean attributes). | 
mdex:boolean-set | 
Represents a Boolean value (TRUE or FALSE). Used for sets (from multi-assign Boolean attributes). | 
mdex:dateTime | 
Represents a date and time to a resolution of milliseconds. Used for atomic values (from single-assign dateTime attributes). | 
mdex:dateTime-set | 
Represents a date and time to a resolution of milliseconds. Used for sets (from multi-assign dateTime attributes). | 
mdex:double | 
Represents a floating point number. Used for atomic values (from single-assign double attributes). | 
mdex:double-set | 
Represents a floating point number. Used for sets (from multi-assign double attributes). | 
mdex:duration | 
Represents a length of time with a resolution of milliseconds. Used for atomic values (from single-assign duration attributes). | 
mdex:duration-set | 
Represents a length of time with a resolution of milliseconds. Used for sets (from multi-assign duration attributes). | 
mdex:geocode | 
Represents a latitude and longitude pair. Used for atomic values (from single-assign geocode attributes). | 
mdex:geocode-set | 
Represents a latitude and longitude pair. Used for sets (from multi-assign geocode attributes). | 
mdex:long | 
Represents a 64-bit integer. Used for atomic values (from single-assign 32-bit integer attributes and single-assign 64-bit long attributes).
 Note that while Dgraph records support both 32-bit integers (mdex:int data type) and 64-bit integers (mdex:long data type), EQL only supports 64-bit integers (i.e., mdex:long data type). This means that if you query an attribute that has a 32-bit integer value, it will appear as a long (64-bit value) in EQL results.

mdex:long-set | 
Represents a 64-bit integer. Used for sets (from multi-assign 32-bit integer attributes multi-assign and 64-bit long attributes). See note for mdex:long data type. | 
mdex:string | 
Represents character strings. Used for atomic values (from single-assign string attributes).  | 
mdex:string-set | 
Represents character strings. Used for sets (from multi-assign string attributes). | 
mdex:time | 
Represents the time of day to a resolution of milliseconds. Used for atomic values (from single-assign time attributes). | 
mdex:time-set | 
Represents the time of day to a resolution of milliseconds. Used for sets (from multi-assign time attributes). |
