annotation metadata schema

https://marine-imaging.com/fair/schemas/annotation-v2.0.0.json

This is an overview of metadata fields of the schema "Annotations of images":
A schema to establish a format for annotations within images (photos and videos) of different shape and by different annotators

image-annotation-labels	All the labels used in the image-annotations. Specified by an id (e.g. AphiaID), a human-readable name and an optional description.
image-annotation-creators	All the annotators that created image-annotations. Specified by an id (e.g. ORCID), a human-readable name and an optional type specifying the annotator's expertise.
image-annotations	This field stores all annotations as a list of dictionaries of 3-4 fields: shape, coordinates, labels and (optional) frames. See further explanations below. The list of labels specifies the IDs or names of objects and annotators and their confidence. These should be specified in an `image-annotation-labels` and `image-annotation-creators` field (see above) to provide more information on the values used in these fields.
