<span class="application">Zebra</span> uses <acronym class="acronym">XSLT</acronym> stylesheets for both <acronym class="acronym">XML</acronym>record
indexing and
display retrieval. In this example installation, they are two
retrieval schema's defined in
<code class="literal">conf/dom-conf.xml</code>:
the <code class="literal">dc</code> schema implemented in
<code class="literal">conf/oai2dc.xsl</code>, and
the <code class="literal">zebra</code> schema implemented in
<code class="literal">conf/oai2zebra.xsl</code>.
The URLs for accessing both are the same, except for the different
value of the <code class="literal">recordSchema</code> parameter:
<a class="ulink" href="http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=dc" target="_top">
http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=dc
</a>
and
<a class="ulink" href="http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra" target="_top">
http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra
</a>
For the curious, one can see that the <acronym class="acronym">XSLT</acronym> transformations
really do the magic.
</p><pre class="screen">
xsltproc conf/oai2dc.xsl data/debug-record.xml
xsltproc conf/oai2zebra.xsl data/debug-record.xml
</pre><p>
Notice also that the <span class="application">Zebra</span> specific parameters are injected by
the engine when retrieving data, therefore some of the attributes
in the <code class="literal">zebra</code> retrieval schema are not filled
when running the transformation from the command line.
</p><p>
In addition to the user defined retrieval schema's one can always
choose from many build-in schema's. In case one is only
interested in the <span class="application">Zebra</span> internal metadata about a certain
record, one uses the <code class="literal">zebra::meta</code> schema.
<a class="ulink" href="http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra::meta" target="_top">
http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra::meta
</a>
</p><p>
The <code class="literal">zebra::data</code> schema is used to retrieve the
original stored <acronym class="acronym">OAI</acronym> <acronym class="acronym">XML</acronym> record.
<a class="ulink" href="http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra::data" target="_top">
http://localhost:9999/?version=1.1&operation=searchRetrieve&x-pquery=the&startRecord=1&maximumRecords=1&recordSchema=zebra::data
