1.1 How Plum persists structure of member pages

Saving of structure begins with:

• POST /concern/scanned_resources/:id/structure => curation_concerns/scanned_resources#save_structure

The #save_structure method in a registered curation concern (i.e. a ScannedResource) comes from:

• CurationConcerns::MemberManagement
• https://github.com/IU-Libraries-Joint-Development/pumpkin/blob/d0e720466e85ac0b89fd5497c51b089775ff326b/app/controllers/curation_concerns/curation_concerns_controller.rb#L5

#save_structure calls SaveStructureJob

• https://github.com/IU-Libraries-Joint-Development/pumpkin/blob/d0e720466e85ac0b89fd5497c51b089775ff326b/app/controllers/concerns/curation_concerns/member_management.rb#L16

Structure passed from form is used to set #logical_order on resource:

• https://github.com/IU-Libraries-Joint-Development/pumpkin/blob/d0e720466e85ac0b89fd5497c51b089775ff326b/app/jobs/save_structure_job.rb#L11

#logical_order comes from:

• https://github.com/IU-Libraries-Joint-Development/pumpkin/blob/d0e720466e85ac0b89fd5497c51b089775ff326b/app/models/scanned_resource.rb#L7
• https://github.com/IU-Libraries-Joint-Development/pumpkin/blob/master/app/models/concerns/structural_metadata.rb

Logical order classes behind #logical_order
