I will try to explain the second question: EntityHub exposes the lookup/find/query entity API and abstracts away all the referenced/managed site material as well as the real backing store.
My requirement is to apply certain filtering (based on security context of a user) for the local (non referenced) repository. While I know how to do this for SOLR, I don't know if I can apply security filtering in Stanbol. Basically, I would at least like to pass through some custom header and be able to retrieve it in SOLR to apply the filter. What could be the shortest workaround for that? Currently I see 2 solutions: 1. Call SOLR API 'as is'. 2. Dig into the code to fetch my header and incorporate into yard request.

Just unpack them and install them on you Solr server. If you want to start from an empty Site you can use [1]. When the Solr Core is available on your Solr server you need to configure the URL to the RESTful API in the "Solr Index/Core" (org.apache.stanbol.entityhub.yard.solr.solrUri) field of the Solr Yard.

But maybe the "Multiple Yard Layout" of the SolrYard could help you. Basically the SolrYard supports the creation of multiple Instances that do access the same Solr Core. To activate this you need to enable the "Multiple Yard Layout" (org.apache.stanbol.entityhub.yard.solr.multiYardIndexLayout). What this does it that the SolrYard will add an additional field '_domain' and store the name of the SolrYard as value for all Entities stored by this SolrYard. Also all queries will use this as an additional constraint. This feature was introduced to allow the storage of multiple (typically small) vocabularies within the same Solr Core but maybe it could be also useful for your usecase. best Rupert > Thanks, > > Alexey > -- | Rupert Westenthaler [email protected] | Bodenlehenstraße 11 ++43-699-11108907 | A-5500 Bischofshofen
