SYNOPSIS

                                    id          => $id,
                                    base_uri    => $xbase,
                                    href        => $href,
                                    nature      => $role,
                                    purpose     => $arcrole,
                                    title       => $title,
                                    lang        => $lang,
                                     );
  # manipulate it in various ways
  $foo = $res->get_id;
  $foo = $res->get_base_uri;
  $foo = $res->get_href;
  $foo = $res->get_nature;
  $foo = $res->get_purpose;
  $foo = $res->get_title;
  $foo = $res->get_lang;

  $res->set_id('foo');
  $res->set_base_uri('foo');
  $res->set_href('foo');
  $res->set_nature('foo');
  $res->set_purpose('foo');
  $res->set_title('foo');
  $res->set_lang('foo');

DESCRIPTION

XML::RDDL::Resource is an interface to a single RDDL Resouce description, as found inside an RDDL document.

METHODS

XML::RDDL::Resource->new(%options)

Creates a new Resource instance. None of the following options are mandatory, but it is recommended that all be set, and of course a Resource that doesn't have a nature, purpose, and href is moderately useful.

  - id
    the ID of the Resource (ought to be unique)

  - base_uri
    the current base URI of the Resource, based on which the href is
    resolved. This doesn't have to be set by an xml:base attribute of
    the rddl:resource element but can also be the base URI of the
    document, or set by the last xml:base in scope.

  - href
    the xlink:href of the Resource which points to the actual resource
    entity.

  - nature
    the nature of the Resource (xlink:role)

  - purpose
    the purpose of the Resource (xlink:arcrole)

  - title
    the title of the Resource (xlink:title)

  - lang
    the lang of the Resource. This doesn't have to be set by an
    xml:lang attribute of the rddl:resource element but can also be
    set by the last xml:lang in scope.

Accessors

All the above options have corresponding get_* and set_* accessors. The get_* only return the value, and the set_* modify it without returning anything.

TODO

    - it may be that more accessors are needed depending on how RDDL
    evolves
    - URI resolution helpers may be wanted
