<p>The Adobe Extensible Metadata Platform (XMP) is a standard, created
by Adobe Systems Inc., for processing and storing standardized and
proprietary information relating to the contents of a file.</p>
<p>XMP standardizes the definition, creation, and processing of
extensible metadata. Serialized XMP can be embedded into a
significant number of popular file formats, without breaking their
readability by non-XMP-aware applications. Embedding metadata ("the
truth is in the file") avoids many problems that occur when
metadata is stored separately. XMP is used in PDF, photography and
photo editing applications.</p>
<p>This API is provided to remove code duplication between extractors
using these standards.</p>

<p>This function applies all regional <em class="parameter"><code>data</code></em>
to <em class="parameter"><code>preupdate</code></em>
and
<em class="parameter"><code>metadata</code></em>
. Regional data exists for image formats like JPEG, PNG,
etc. where parts of the image refer to areas of interest. This can
be people's faces, places to focus, barcodes, etc. The regional
data describes the title, height, width, X, Y and can occur
multiple times in a given file.</p>
<p>This data usually is standardized between image formats and that's
what makes this function different to <a class="link" href="libtracker-extract-XMP.html#tracker-xmp-apply" title="tracker_xmp_apply ()"><code class="function">tracker_xmp_apply()</code></a> which is
useful for XMP files only.</p>
