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