Metacat

Add check in iindex unit test for 'prov_hasDerivations' field

Merge the code for rdfxml subprocessor from d1_cn_index_processor to metacat.

Add the prefix "prov_" the solr fields.

Use a new class to overwrite the class RdfXmlSubprocessor in d1-processor since that one has a method to use solr http server directly.

use input stream instead of Document for resource map processing test

update to use v2 types for indexing

use default "metacat" context name for metacat-index testing.

use a non-public rightsHolder for both EML and Annotation test documents now that the RDF subprocessor checks each annotation to see that it came from a user that as write permission for the object being annotated.

test for update using the updated EML file, not the original. Also add the SM to the shared map so that the indexing process can consult SM.accessPolicy when indexing annotations that assert things about those test documents.

ignore the metacat/solr comparator tests - they are one-offs.
