The AbstractInspector is the base class of providing a check of the metadata while writing it to
the metadataStore (this will affect the transaction operation by inserting or updating the metadata).
If provided, this element turns on the schema-validation of the metadata.
True, if the metadata should be rejected if there is no fileIdentifier available, otherwise
there is no rejection.
True, if the metadataStore should generate the resourceIdentifier automatically while there
is no one provided by the metadata, otherwise there is no automatic generating.
True, if there should be thrown an exception and the metadata should not be inserted.
