+ <title>BIBFRAME</title>
+ <para>
+ The MARC to BIBFRAME was the primary purpose of the XQuery
+ module for Metaproxy, but generally the module is a just an alternative
+ to record_transform filter of Metaproxy which primarily performs XSLT.
+ </para>
+ <para>
+ The <filename>bibframe directory</filename> of the source tar
+ contains sample file for performing MARC to BIBFRAME conversions.
+ Upon <literal>make install</literal> these are installed to directory
+ <filename>/usr/share/mp-xquery/bibframe</filename> and they are also
+ part of the package <literal>mp-xquery</literal>.
+ </para>
+ <para>
+ <literal>config.xml</literal> is a complete Metaproxy configuration file.
+ It includes a standalone configuration that makes Metaproxy offe
+ Z39.50 and SRU support on port 9070. The modules in use are http_file
+ (to serve XSL files), sru_z3950 (SRU service), cql_rpn (CQL to RPN
+ conversion), xquery (to convert MARCXML to BIBFRAME), record_transform
+ (to convert MARC21 to MARCXML), virt_db (for database rewrite), log
+ (to perform backend logging) and, finally, z3950_client to interface
+ a Z39.50 target.
+ </para>
+ <para>
+ It is important that the XQuery module comes before the
+ "record_transform" so that the XQuery module sees XML
+ <emphasis>only</emphasis> and not ISO2709-records.
+ If it does, they will be ignored (passed through) by the XQuery module.
+ </para>
+ <para>
+ The XQuery module script name points to the full path of
+ <filename>zorba3-0.xqy</filename> part
+ of marc2bibframe . Do not move <filename>zorba3-0.xqy</filename>
+ from its place within the
+ marc2bibframe directory as other files are referred to and their relative
+ location must be preserved.
+ </para>
+ <para>
+ File <filename>cql2pqf.txt</filename> contains a simple DC/CQL profile
+ for driving a CQL to RPN conversion.
+ It is referred to from the cql_rpn filter in config.xml .
+ </para>
+ <para>
+ File <filename>explain.xml</filename> is SRU explain configuration.
+ It is referred to from the sru_z3950 filter in config.xml .
+ </para>
+ <para>
+ Directory <filename>xsl/..</filename> is client side XSL for brief -
+ and full display. These must be located so that the http_file filter
+ can fetch them. For example, if these files are located in
+ <filename>/usr/share/mp-xquery/bibframe/xsl</filename> , then
+ http_file would hold
+ <screen><![CDATA[
+ <filter type="http_file">
+ <area>
+ <documentroot>/usr/share/mp-xquery/bibframe/xsl</documentroot>
+ <prefix></prefix>
+ <passthru>true</passthru>
+ </area>
+ </filter>
+]]>
+ </screen>
+ </para>
+ <note>
+ <para>
+ Do not modify the files below <filename>/usr/share/mp-xquery</filename>.
+ They will be overwritten by a package update and if
+ <literal>make install</literal> is executed.
+ Use them if they can be used as-is but copy them away if you want to
+ modify them (such as <filename>config.xml</filename>).
