resolve predicate warnings

[jcoyne]

I'm seeing these warnings in the log:

Same predicate (http://purl.org/dc/elements/1.1/creator) used for properties file_author and creator
Same predicate (http://purl.org/dc/elements/1.1/language) used for properties file_language and language

we should figure out why this is happening and how to resolve it.

More information on this issue. The problem seems to be somewhere in FileSet.

Class FileSet is defined in .internal_test_app/app/models/file_set.rb as follows:

# Generated by curation_concerns:models:install
class FileSet < ActiveFedora::Base
  include ::CurationConcerns::FileSetBehavior
  include Sufia::FileSetBehavior
end

The warning is raised when Ruby processes include ::CurationConcerns::FileSetBehavior. I am still digging but wanted to update the ticket in case somebody has any ideas.

I think the root of the problem is that module CurationConcerns::FileSetBehavior includes CurationConcerns::BasicMetadata and Hydra::Works::Characterization::DocumentSchema and there is a property on each of these modules that uses the http://purl.org/dc/elements/1.1/creator predicate.

This is the line in which CurationConcerns::BasicMetadata defines a property that uses the DC:Creator predicate https://github.com/projecthydra-labs/curation_concerns/blob/master/app/models/concerns/curation_concerns/basic_metadata.rb#L18

This is the line in which Hydra::Works::Characterization::DocumentSchema defines property that uses the DC:Creator predicate: https://github.com/projecthydra-labs/hydra-works/blob/master/lib/hydra/works/characterization/schema/document_schema.rb#L4

With https://github.com/projecthydra-labs/curation_concerns/pull/721 now merged this will be fixed once we get the next version of Curation Concerns.
