We need to add schema.org structured data to all images on Commons and images **from** Commons on Wikipedia in order to meet [[ https://developers.google.com/search/docs/guides/intro-structured-data#structured-data-format | Google's requirements ]] (see also here https://developers.google.com/search/docs/data-types/image-license-metadata) and continue to have the images appear in Google searches.
We are looking at an approximate deadline of November 2020 to complete this work.
When the web team added a schema.org script to article pages, they set up an A/B test to ensure SEO was positively affected, and they confirmed that the added page weight was within acceptable limits. Adding the license data is not optional for us, but we should still determine if our work impacts page weight/performance so we can mitigate this if possible and communicate the change to those who may be concerned about it.
