[Stories] Collecting inventory of metadata, images, dates for CMM

[moranegg]

This issue is a placeholder to collect and identify the inventory for a SWH-Story.
@emulatingkat has agreed to add the metadata into Wikidata and create links with the items on the web.
We need someone from the Pisa team to upload the content (images, slides, videos, etc.) to Wikimedia commons.

• wikimedia gallery
