10.2.a Custom metadata examples
The following is a fragment of XML metadata from a Component. It contains some
basic metadata about the Component and an additional embedded schema,
containing more useful information about the Component.
<?xml version="1.0" encoding="UTF-8"?>
<metadata>
<author>Niels</author>
<some-embedded-schema>
<country><!--also embedded-->
<code>nl</code>
<language>dutch</language>
<fullname>The Netherlands</fullname>
</country>
<city>Amsterdam</city>
</some-embedded-schema>
</metadata>
Truncating metadata
Truncation removes all nested elements, and only stores the top-level elements.
The example above, is stored as:
author=Niels
Flattening metadata
Flattening removes the hierarchy, and all elements are stored as though they are
on the same level. For example:
author=Niels
code=nl
language=dutch
fullname=The Netherlands
city=Amsterdam
