RDF.ex v0.6.1 RDF View Source
The top-level module of RDF.ex.
RDF.ex consists of:
modules for the nodes of an RDF graph
- a facility for the mapping of URIs of a vocabulary to Elixir modules and
functions:
RDF.Vocabulary.Namespace modules for the construction of statements
modules for collections of statements
- functions for working with RDF serializations:
RDF.Serialization behaviours for the definition of RDF serialization formats
and the implementation of various RDF serialization formats
This top-level module provides shortcut functions for the construction of the basic elements and structures of RDF and some general helper functions.
For a general introduction you may refer to the guides on the homepage.

default_prefixes() View Source
A user-defined RDF.PrefixMap of prefixes to IRI namespaces.
This prefix map will be used implicitly wherever a prefix map is expected, but not provided. For example, when you don't pass a prefix map to the Turtle serializer, this prefix map will be used.
By default the standard_prefixes/0 are part of this prefix map, but you can
define additional default prefixes via the default_prefixes compile-time
configuration.
For example:
config :rdf,
default_prefixes: %{
ex: "http://example.com/"
}If you don't want the standard_prefixes/0 to be part of the default prefixes,
or you want to map the standard prefixes to different namespaces (strongly discouraged!),
you can set the use_standard_prefixes compile-time configuration flag to false.
config :rdf,
use_standard_prefixes: falsedefault_prefixes(prefix_mappings) View Source
Returns the default_prefixes/0 with additional prefix mappings.
The prefix_mappings can be given in any format accepted by RDF.PrefixMap.new/1.
