Metacat

merge CN annotation context files to metacat (MN) to support semantic index fields.

use new IDocumentDeleteSubprocessors to handle clean-up of annotation index fields when annotations are removed.

move RDF/XML subprocessor and example configuration with SPARQL query to the cn index project from metacat so that it can be used by prov team when indexing ProvONE models in ORE documents

add fieldsToMerge property for annotation updates

update classes and context files that use cn-index-processor classes. allowing document subprocessors to be less tied to XML.

use sparql field and triple store from cn-index_processor (refactor). include annotatorSubprocessor for testing in metacat-index

let metacat-index lookup annotations for indexing rather than the metacat "reindex" action.

When indexing annotations from RDFs, use the doc id to access the system metadata, not the model name since they are not always the same.

Add PROV relationships to the Solr schema. Populate the fields using the RdfXmlSubprocessor

Add wasDerivedFrom field to the Solr schema and use Sparql query to retrieve the value from the RDF
