/**
* RDF vocabulary describing assertions in inner datasource
*
* For a particular resource, we want to provide all arcs out and
* in that the inner datasource has.
* This is done by introducing helper resources for each triple of
* the form
* x-moz-dsds:<subject-resource-pointer><predicate-resource-pointer>\
* <object-node-pointer>
* For each triple, that has the resource in question as subject, a
* "arcsout" assertion goes from that resource to a x-moz-dsds resource.
* For each triple, that has the resource in question as object, a
* "arcsin" assertion goes from that resource to a x-moz-dsds resource.
* For each x-moz-dsds resource, there is a "subject" arc to the subject,
* a "predicate" arc to the predicate and a "object" arc to the object.
*
* The namespace of this vocabulary is
* "http://www.mozilla.org/rdf/vocab/dsds".
*
* XXX we might want to add a "qname" resource from each resource to a
* somewhat canonical "prefix:localname" literal.
