IIIF Object Derivatives Do Not Validate

This is a Linked Data challenge, and also questions the default functionality of the RERUM API.

I went through the `navPlace` workflow and generated a derivatives of the IIIF Cookbook Simple Manifest https://iiif.io/api/cookbook/recipe/0001-mvm-image/manifest.json. The resulting derivative is https://store.rerum.io/v1/id/650b1fdf64451a9d0a8e1091.

This derivative should pass IIIF validation.

### Validation Interface at https://presentation-validator.iiif.io/

Start by reproducing the navPlace workflow with the IIIF Cookbook Simple Manifest and inspect the generated derivative at the linked RERUM URL. Run that derivative through the IIIF Presentation Validator and compare the reported failures with the workflow output; done means the derivative passes IIIF validation.
