Synopsis feature

On API side, we need a mechanism (or a convention) to describe that two or more sections of texts in two or more separate items are the same. This data is then used in TIDO for the synopsis feature.

Paul's current draft looks like the following:

{
  "@context": "http://www.w3.org/ns/anno.jsonld",
  "id": "example/annotationPage",
  "type": "AnnotationPage",
  "partOf": {
    "id": "example/annotationCollection",
    "label": "Synopsis connections"
  },

        }
      \],
      "type": "Annotation",

          "format": "text/xml"
        }
      \],
      "type": "Annotation",
      "id": "example/manifest-1/item-1/annotation-2"
    }
  \]
}

We need to check if this is possible within the W3C Web Annotation Data Model or, if not, create a new API for this.
