NAME

       HTML::Microformats::Format::OpenURL_COinS - the OpenURL COinS poshformat

SYNOPSIS

        use HTML::Microformats::DocumentContext;
        use HTML::Microformats::Format::OpenURL_COinS;
        use Data::Dumper;

        my $context = HTML::Microformats::DocumentContext->new($dom, $uri);
        my @objects = HTML::Microformats::Format::OpenURL_COinS->extract_all(
                          $dom->documentElement, $context);
        my $object = $objects[0];
        print Dumper($object->data);

DESCRIPTION

       HTML::Microformats::Format::OpenURL_COinS inherits from HTML::Microformats::Format. See the base class
       definition for a description of property getter/setter methods, constructors, etc.

MICROFORMAT

       OpenURL COinS is not technically a microformat. It was developed outside the microformats community and
       does not use many of the patterns developed by that community. Nevertheless it's an interesting format,
       and perhaps a useful one.

       HTML::Microformats::Format::OpenURL_COinS supports COinS as described at <http://ocoins.info/>, with the
       following addition:

       •   Support for additional elements and attributes

           OpenURL  COinS is only specified to work on <span> elements.  This module allows its use on arbitrary
           HTML elements. When used with <q> or <blockquote> the 'cite' attribute is consulted in preference  to
           'title'; when used with <link>, <a> or <area>, 'href' is used in preference to 'title'.

           When  either  of  the  'cite' or 'href' attributes is used, any leading string ending with a question
           mark is removed from the attribute value prior to OpenURL processing. This allows  for  the  attibute
           values to be published as proper links.

           When  <q>  or <blockquote> is used, the quote is taken to be sourced from the entity described by the
           context object.

RDF OUTPUT

       Like how HTML::Microformats::Format::hCard differentiates  between  the  business  card  and  the  entity
       represented  by  the  card,  this  module differentiates between the OpenURL context object and the book,
       journal entry or other publication represented  by  it.  The  former  is  essentially  a  set  of  search
       parameters which can be used to find the latter.

       The  RSS  Context  module (<http://www.openurl.info/registry/fmt/xml/rss10/ctx#>) is used to describe the
       context   object.   The   Bibo    ontology    (<http://purl.org/ontology/bibo/>)    and    Dublin    Core
       (<http://purl.org/dc/terms/>) are used to describe the work itself, with data being "back-projected" from
       the context object where not too complicated.
