Changelog#

v2.2.1#

requirements for the image-context field. It previously missed the constraint of having a name field
constraints of the image-overlap-fraction field. It now also allows zero as a value
description of the image-entropy field. It now correctly defines the field’s value as the normalized Shannon entropy

image-stereo-camera-calibration-model field to support stereo images.
image-platform field description, to include organisms (e.g. diver) as a platform.
new icons for image annotation values
datacite references for context
handles for schema identifier

data structure description of image-set-items, to clarify that only still images are given as objects and videos as lists
field descriptions, for image-sensor, image-creators and image-license
image-creators field to have at least one entry
image-camera-housing-viewport.viewport-type field to be defined as an enumeration
typo in image-average-color field description
maximum value of image-average-color field, so the field is actually represented by an 8 bit unsigned integer
missing descriptions of image-annotations.shape variants
description of image-coordinate-uncertainty-meters to clarify that it is limited to horizontal coordinates only
schema references in examples

image-provenance field to document the agents, entities and activities that led to the creation. This field is inspired by the definition of w3-prov
image-related-material field to reference information in external resources that relates to this iFDO (e.g. cruise reports).
image-set-[min,max]-[latitude,longitude]-degrees fields to to define a bounding box within which all images of the iFDO reside

schema definition to be split between iFDOs, annotations and the provenance
file format recommendation to JSON
many fields that used to be strings to objects to provide not only a value but also a link to external resources, e.g. image-platform: {name: PFM-XYZ, uri: https://foobar/PFM-XYZ}. Others fields that are affected: image-sensor, image-license, image-context, image-project, image-event, image-pi
the iFDO image-set-header part to requiere one representative value for each of these fields: image-datetime, image-latitude, image-longitude, and image-altitude-meters
spelling of fields and added unit names to appropriate fields, e.g. image-altitude which is now called image-altitude-meters and image-area-square-meter which is now called image-area-square-meters

image-depth field to remove the ambiguity of having two options for altitude / depth
