Hello -

I'm Adam Baso, an engineering director at the Wikimedia Foundation. We
wanted to let the Schema.org community know that we're A/B testing the
sameAs property on Wikipedia articles having a corresponding Wikidata
entry. We're running the test on most [1] Wikipedias, including English
Wikipedia. You can see this in effect for the markup on the English article
for War of the Polish Succession

We have applied the new property to 50% of Wikipedia pages with
corresponding Wikidata entries by way of the Article type. Our CDN is being
populated with this change so you should see more of this markup. We'll be
running this A/B test for about two months and will be evaluating results
along the way.

One motivation for this work is to explore the effect of the changes on
search relevance. More generally, we're also interested in how structured
markup like this on Wikimedia content projects might be beneficial to the
semantic web and machine readability, much along the lines of other
Wikimedia movement initiatives such as Structured Data on Commons

Any feedback you have on our implementation in this A/B test would be most
welcome. Please share your feedback with Olga Vasileva (
ovasileva@wikimedia.org). Thanks!
