+=head1 NAME
+
+KorAP::XML::Meta::I5 - Parses I5 meta data of a KorAP-XML document
+
+=head1 DESCRIPTION
+
+Parses I5 meta data of a KorAP-XML document.
+
+Following the data model, all 3 levels of metadata are parsed, while not all
+metadata levels contain the same information. The precedence is that metadata
+defined on the text level will override metadata on the document level. And
+metadata on the document level will override metadata on the corpus level.
+
+=head2 Metadata categories
+
+Krill currently supports the following types of metadata to be indexed.
+They differ especially in the way they can be used to construct a virtual corpus.
+
+=over 2
+
+=item B<String>
+
+A simple string representation of a meta data field. Useful for fixed values,
+such as I<corpusSigle> or I<language>.
+
+=item B<Text>
+
+A string representation that will be indexed as a text, so fulltext search
+(like phrase search) is supported. Useful for values where partial matches are
+useful, like I<title> or I<author>.
+
+=item B<Keywords>
+
+Multiple string representations. Identical to string, but supports multiple
+values in the same field. Useful for multiple given values such as I<textClass>.
+
+=item B<Attachement>
+
+Values that can't be used for the construction of virtual corpora, but are stored
+per document and can be retrieved. Useful for static data to be retrieved such as
+I<reference> or I<externalLink>.
+
+=item B<Date>
+
+A representation of a date, that can later be used for date range queries to construct
+virtual corpora. Useful for all date related information, such as I<pubDate> or I<createDate>.
+
+=back
+
+=head2 Metadata fields
+
+Currently L<KorAP::XML::Meta::I5> recognizes and transfers the following fields, given as
+a SCSS selector rule (plus C<@> for attribute values) followed by the field name and
+the metadata category.
+The order may indicate a field to be overwritten.
