Some examples about how your objects in IIIF (the bridge to the Human Presentation API) link to semantic description (your model, or other shared models). The IIIF manifests for all "catalogue" objects would link to a semantic description via the seeAlso property:
A link to a machine readable document that semantically describes the resource with the seeAlso property, such as an XML or RDF description. This document could be used for search and discovery or inferencing purposes, or just to provide a longer description of the resource. The profile and format properties of the document should be given to help the client to make appropriate use of the document.
While your catalogue Manifests link to some experimental RDF, your IIIF Collections currently don't link to seeAlso resources, but they should, expecially when you start making ad hoc curated collections. And similarly for ad hoc manifests.
