Yes Steve, you are correct. That is where the problem is. I haven't tried your method, but I just modified the Muradora code to not look for the prefix. Although, I'm sure your method may be the better solution
Either way, I would have to modify Muradora's code and reindex Solr. Thanks!

Subject: Re: [fcrepo-user] addRelationship API affects existing namespace Hi Vincent It looks like it is the processing of the XML that is at fault - semantically the XML (and also the RDF) is the same whatever the namespace prefix. Presumably you are using a variant of the indexing stylesheet at http://www.muradora.org/muradora/attachment/wiki/InstallMuradoraSolr/dem oFox mlToSolr.xslt, which is a variant of the standard GSearch indexing stylesheet? This is mapping relationship predicates to SOLR names based on the namespace prefix, which means the indexing will break if the exact namespace prefix isn't used in the XML. The offending code is: ----- <xsl:for-each select="foxml:datastream[@ID='RELS-EXT']/foxml:datastreamVersion[last()] /fox ml:xmlContent/rdf:RDF/rdf:Description/*"> <field > <xsl:attribute name="name"> <xsl:value-of select="concat('rdf.', translate(name(), ':', '.'))"/> </xsl:attribute> <xsl:value-of select="substring-after(@rdf:resource, 'info:fedora/')"/> <xsl:value-of select="text()"/> </field> </xsl:for-each> ----- Specifically it is the expression: concat('rdf.', translate(name(), ':', '.')) This is building the Solr name from the namespace-prefix:node-name To use specific values in Solr field names for specific namespaces, you could try something like: ----- <xsl:for-each select="foxml:datastream[@ID='RELS-EXT']/foxml:datastreamVersion[last()] /fox ml:xmlContent/rdf:RDF/rdf:Description/*"> <field > <!-- map predicate namespaces to a prefix for the field name --> <xsl:variable name="relNamePrefix"> <xsl:choose> <!-- Fedora relationships namespace -> rels --> <xsl:when test="namespace-uri='info:fedora/fedora-system:def/relations-external#'" > <xsl:text>rels</xsl:text> </xsl:when> <!-- Fedora model namespace -> fedora-model --> <xsl:when test="namespace-uri='info:fedora/fedora-system:def/model#'"> <xsl:text>fedora-model</xsl:text> </xsl:when> <!-- add more tests as needed here ... --> <!-- un-mapped namespaces -> other --> <xsl:otherwise> <xsl:text>other</xsl:text> </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:attribute name="name"> <xsl:value-of select="concat('rdf.', $relNamePrefix, local-name())"/> </xsl:attribute> <xsl:value-of select="substring-after(@rdf:resource, 'info:fedora/')"/> <xsl:value-of select="text()"/> </field> </xsl:for-each> ----- NB I haven't actually tested this... so it might need some tweaking; but hopefully you can see the principle - generate Solr field names based on the actual namespace, not the namespace prefix.
