NAME

RDF::NS::Curated - A curated set of RDF prefixes

SYNOPSIS

  my $ns = RDF::NS::Curated->new;
  print $ns->uri('foaf'); # prints http://xmlns.com/foaf/0.1/
  print $ns->prefix('http://schema.org/'); # prints schema

DESCRIPTION

This contains a list of 62 prefix and URI pairs that are commonly used in RDF. The intention is that prefixes in this list can be safely used in code that has a long lifetime. The list has been derived mostly from W3C standards documents, but also some popularity lists. See the source code of this package for the full list.

It is intended to be used with e.g. URI::NamespaceMap.

Methods

new

Constructor. Takes no arguments.

uri($prefix)

This will return the URI (as a plain string) of the supplied prefix or undef if it is not registered.

prefix($uri)

This will return the prefix corresponding to the supplied URI string or undef if it is not registered.

qname($uri)

This will return the qualified name corresponding to the supplied URI string or undef if it is not registered. In scalar context, it will return the prefix and local name with a colon, and list context, a two-element array containing prefix and local name.

For example http://purl.org/dc/terms/name will return dc:name in scalar context and ('dc', 'name') in list context.

all

This will return a hashref with all prefix and URI pairs.
