The following Audiovisual Core terms are recommended for describing an image's alternate resolutions, formats, or other versions:

Further information on how to handle multiple versions is available in section 3.2 of the Audiovisual Core Structure document.

In the example-record:

  • ac:variant indicates that a "medium-Quality" version of the image is available with "Further-Information."
  • ac:hasServiceAccessPoint provides the alternate version's URL.

3 Further Examples

See the ImageExamples tab in this google doc

3.1 Images of Text or Sound?

Following the Dublin Core recommendations for the Text type, images of text (e.g., Catalog Cards) should be described as type Text.
Similarly, visualizations of sound (e.g. Spectrograms) should be documented as type Sound.

3.2 Photographs of Living Organisms vs Museum Specimens

The differences between a photograph of a living organism and one of a museum specimen is mainly reflected in the related Darwin Core occurrence records. If the photographs were both recorded with similar camera-setups, the recommended Audiovisual Core terms would be the same, with one distinction:

3.3 Camera-traps

Note that photographs recorded with camera traps or other sequential or repeated image-recording methods can benefit from other detailed documentation. (Consider https://www.mdpi.com/1424-8220/21/2/343/html)
