Include rdf:type expressed in Entry-information in Solr index
In certain cases it is important to type entrys but not have it included in metadata, the rationale is:
The metadata should not be polluted with additional type information that is only used to provide administrative hints (e.g. used by the user interface)
The type should be considered a bit more important and should only be possible to change by owners.
Even though the type is provided in the entry-information it should still be possible to search for entrys of this type, e.g. type expressed using rdf:type in entry-information should be included in the rdftype solr field.
Note: the existing entry, resource and graph types that are expressed via rdf:type in the entry:information need not be included in the solr index since they have separate fields.
A good example is when we need to type contexts to be of type "Catalog", "Term container", or some workbench specific flavour. This information is important to include in searches but should only be editable by those who own the context.
