=head1  Playing with document metadata

An office document owns a set of so-called I<"metadata">. Metadata is "data
about the document". For the end user, it may be got (and sometimes changed)
through the "File/Properties" sub menu of a typical desktop software. lpOD
allows the programmer to select, read or write any piece of metadata.

=head2  Pre-defined metadata

A document may contain some global metadata. The most commonly used ones are
the I<title>, the I<subject>, the I<description>, the I<creation date>, the
I<modification date>, the I<creator>, and others. All that is stored in the
C<META> document part. We can get access to any piece of metadata through the
C<META> context. Note that the C<META> document part is directly usable as the
context for metadata access, so we don't need to look for a particular I<body>
