RDF.XSD.Datatype.Restriction (RDF.ex v0.9.2) View Source

A __using__ macro for the derivation of restricted XSD datatypes.

Example

A new custom datatype can be derived by defining a new datatype module and use this module, specifying a name, id and base datatype and restricting it by specifying some of the applicable facets of the base datatype:

defmodule MyApp.PersonAge do
  use RDF.XSD.Datatype.Restriction,
      name: "person_age",
      id: "http://example.com/person_age",
      base: RDF.XSD.NonNegativeInteger

  def_facet_constraint RDF.XSD.Facets.MaxInclusive, 150
end

See RDF.XSD.Facet on which facets are available on the existing datatypes.
