Yes this happened sometimes before
https://issues.apache.org/jira/browse/STANBOL-519 got fixed. But as this only
appeared if new - formally unknown namespaces where added to a SolrIndex used
by the SolrYard. Because of that it is nearly impossible to appear with the RDF
namespace.
The prefix mappings are stored in a SolrDocument with the ID
"urn:eu.iksproject:rick.yard.solr:config.namespacePrefixConfig".
You can actually look at the present mappings by querying for
q=uri:urn\:eu.iksproject\:rick.yard.solr\:config.namespacePrefixConfig
e.g.
http://dev.iks-project.eu:8081/solr/default/dbpedia/select?q=uri:urn\:eu.iksproject\:rick.yard.solr\:config.namespacePrefixConfig
This document should define a field like
<arr name="_config/rdf">
<str>
http://www.w3.org/1999/02/22-rdf-syntax-ns#
</str>
</arr>
defining the RDF namespace.
Reto can you place check this.
