Artwork: Return values for artwork artist and photographer artist See example URL: The fountain has a sculptor as artist and the image was taken by a photographer. Both values are needed for a proper attribution. Currently the photographer is not mentioned in the output.

Please parse https://commons.wikimedia.org/wiki/Template:Art_Photo too. Same issue here.
While CommonsMetadata does parse these templates, it only returns data from the first infobox-like template on the page. This is mostly a limitation of the current API output format (bug 57259 has more details).
