Support multiple motivations for a single annotation

[elynema]

Is your feature request related to a problem? Please describe.
Annotations in manifests produced by AVAnnotate seem to often contain multiple motivations. In the example below, there is a textual annotation that is labeled as both supplementing and commenting.

Describe the solution you'd like
It is currently unclear the best solution. In this example, it seems that the commenting motivation is the most meaningful. Perhaps discuss with AVAnnotate team the purpose of the additional supplementing motivation.

In some scenarios, might we display the annotation twice to respond to both motivations?

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
Here is an example from this manifest: https://lgsump.github.io/maya-deren-example/meshes-of-the-afternoon/manifest.json

"@context": "http://www.w3.org/ns/anno.jsonld",
      "id": "meshes-of-the-afternoon-canvas-1-shadow-annotation-0.json",
      "type": "Annotation",
      "motivation": [
        "supplementing",
        "commenting"
      ],
      "body": {
        "type": "TextualBody",
        "value": "Here we get the first glimpse at something important to understanding the artist’s play with shadow in that the form already is chosen in Black & White film.",
        "format": "text/plain",
        "purpose": "commenting"
      },
      "target": {
        "source": {
          "id": "https://lgsump.github.io/maya-deren-example/meshes-of-the-afternoon/canvas-1/canvas",
          "type": "Canvas",
          "partOf": [
            {
              "id": "https://lgsump.github.io/maya-deren-example/meshes-of-the-afternoon/manifest.json",
              "type": "Manifest"
            }
          ]
        },
        "selector": {
          "type": "PointSelector",
          "t": "16"
        }
      }

Done Looks Like

• Email to AVAnnotate members about what they would like to see when there are multiple motivations
• How are the Aviary player and AVAnnotate rendering multiple motivations for an annotation in a manifest documents?

Right now Aviary is able to display these manifests but Ramp is not. We can look at the Aviary player for how implementation goes, and talk to AVAnnotate project members to get more background on how the supplementing motivation is being used. We can then make changes to support the expectations of rendering when there are multiple motivations.
