Update the validator to expect the four fields that the Drupal API actually passes.
Record og_references for core files on create.
Delete superfluous comment.
Add a 'project_members' field to the properties datastream to track the UIDS of drupal users associated with a given Community (drupal project).  Note that this isn't solrized, as the value is never expected to be used for anything other than passing to eXist.
Don't need to explicitly delegate :nid= and :og_reference=, has_attributes handles that.
Delete goofy comments.
Create communities from API requests.
