[ldd-rings] Define Local_Internal_Reference in Ring_Reprojection

[mace-space]

Describe the issue identified (if applicable)

Issue motivated by a reprojected image requiring a display direction. pds:Local_Internal_Reference should be required by the Ring_Reprojection class. The Display_Direction class that was copied & pasted from the Display dictionary needs to be removed from the Rings dictionary (Issue #242), but a reference to the Display dictionary's Display_Direction needs to be made. So in the Ring_Reprojection class, we need pds:Local_Internal_Reference (to use local_identifier_reference).

Describe the solution you'd like

Steps required:

• a schematron rule that defines local_reference_type in this class (“reprojection_to_array”). Uniformly_Sampled_Radius provides a useful template:

  <DD_Rule>
      <local_identifier>Uniformly_Sampled_Radius_0</local_identifier> 
      <rule_context>//rings:Uniformly_Sampled_Radius/pds:Local_Internal_Reference</rule_context>
      <DD_Rule_Statement>
          <rule_type>Assert</rule_type>
          <rule_test>pds:local_reference_type = 'uniformly_sampled_radius_to_array_axis'
          </rule_test>
          <rule_message>For Local_Internal_Reference in rings:Uniformly_Sampled_Radius, local_reference_type must equal 'uniformly_sampled_radius_to_array_axis'.
          </rule_message>
      </DD_Rule_Statement>
  </DD_Rule>

• a schematron rule that says that the mosaic needs to have a display direction, i.e. <rings:Ring_Reprojection>.<Local_Internal_Reference>.<local_identifier_reference> has to be present in one of <disp:Display_Settings>.<local_identifier_reference> (I say “one of” because there isn’t anything to preclude multiple images (only one of which is reprojected, say) in a label where each would have a display direction). The Display dictionary currently contains the following:

  <DD_Rule>
  <local_identifier>Display_Settings_0</local_identifier>
  <rule_context>disp:Display_Settings/pds:Local_Internal_Reference</rule_context>
  <DD_Rule_Statement>
      <rule_type>Assert</rule_type>
      <rule_test>pds:local_identifier_reference = //pds:*/pds:*/(pds:Array|pds:Array_2D|pds:Array_2D_Image|pds:Array_2D_Map|pds:Array_2D_Spectrum|pds:Array_3D|pds:Array_3D_Image|pds:Array_3D_Movie|pds:Array_3D_Spectrum)/pds:local_identifier
      </rule_test>
      <rule_message>Display Dictionary: In the pds:Local_Internal_Reference class, the value of the pds:local_identifier_reference must match the value of the pds:local_identifer of an Array class or sub-class within the File_Area.
      </rule_message>
  </DD_Rule_Statement>
  <DD_Rule_Statement>
      <rule_type>Assert</rule_type>
      <rule_test>pds:local_reference_type = 'display_settings_to_array'
      </rule_test>
      <rule_message>Display_Dictionary: For Local_Internal_Reference in disp:Display_Settings, local_reference_type must equal 'display_settings_to_array'.
      </rule_message>
  </DD_Rule_Statement>
  </DD_Rule>
