Datatype (or propertyType) is an attribute of a property specifying the type and shape of the value in each claim. Each property is assigned a pre-defined datatype, which usually can not be changed. Not all values can be linked, as long as there are certain datatypes missing. Data types can only be defined by developers; the development of new datatypes is still in progress. See also $spec-ldt for currently available datatypes. Data type does not directly specify how values are stored internally; this is specified by value type.
