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.
