    The property 'dtype:value' is a general property that in some cases could have scalar values and in other cases may refer to a first class concept that is a 'value object'. For this reason, the  type of this property is set as 'rdf:Property' and the property is rangeless.

    A codelist is a controlled vocabulary of terms that are used to represent permissible values of a variable in information systems. The representaiton of codes in 'dtype' has been influenced by CCTS and UBL.
    
    Enumeration

    A type that serves as a container for the enumerated values of an enumeration. This enables the enumeration itself to be referenceable. One need for this is in determing the default value of an enumeration , another need is in the management of sub-enumerations and composite enumerations.

    The base class for datatypes that have values that are restriced to a set of literals or tokens. The members of the restriction may themselve be restriced by facets that apply to scalar data types.

    The property 'dtype:orderIndex' is an annotation property to specify a position that some value or structure will have. One use is to specify the place that a resource has in a sequence. One use is on property occurrences in class axioms. Here 'vaem:orderIndex' is placed on a restriction to specify how that property may be transformed into a representation where ordering has some importance, for example, in XML Schema sequences.

    Datatype Ontology
    http://www.linkedmodel.org/schema/dtype
    
    The ontology 'dtype' provides a specification of simple data types such as enumerations. These are needed in support of the conversion of XML Schemas and UML Models to OWL. Codelists are also defined in 'dtype'.

    The property 'dtype:defaultValue' is a general property for specifying a value in situations where none is specified, or can be determined. In some cases of use, this property could have a scalar value and in other cases may need to refer to a first class concept that holds a 'value object'.  For this reason, the  type of this property is set as 'rdf:Property' and the property is rangeless.

    The property 'dtype:order' provides a means to specify a precedence. One use of order is in specifying ordered enumerations such as 'voag:ConfidentialityLevel'.  A similar property, but with an important type difference, is 'vaem:orderIndex'. This is for use on property occurrences in class axioms where it can be placed on a restriction to specify how that property may be transformed into other representations where ordering has some importance, for example, in XML Schema sequences.  Whereas 'vaem:order' is a datatype property, 'vaem:orderIndex' is an annotation property.
