Significant changes in version 1.02 include:
Added a new profile
PosedCollectionand elements for
NavigationalConnectivityto support a Streetview-style use case (collections of posed panorama images and scene geometry).
Significant changes in version 1.01 include:
Added a new
Profileelement for describing the intended use case of the container image with the XDM metadata. For example, the XDM metadata for a depth photo is structurally different from that for a virtual reality photo. This element allows an image reader to quickly identify the media type without having to parse all the metadata, and identify the intended usage of each camera listed in the
EquirectModelto support rendering for equirectangular panoramas.
FisheyeModelto support rendering for equirectangular panoramas.
Audiofields (data and media type) to
Camerathat represent an audio track. An example use case is recording audio with an image, such as with virtual reality photography.
Device, originally intended as a required field for detecting whether or not a container image was edited by a non-XDM-aware app. Computation of the signature is non-trivial, and therefore not likely to be universally implemented.
PerspectiveModel, to support other distortion models such as that for a fisheye lens.
DevicePose. This simplifies the access to global capture time information without having to search for a particular
