The BetaCluster json+ls incorrectly fills the sameAs property in the jsonld schema. The sameAs should point to the betacluster wikibase, not to the production one.
Steps to reproduce
- Go to https://en.wikipedia.beta.wmflabs.org/wiki/World (which is linked to Q500927)
- Hover over a WikiBase item menu item on the left side (Vector skin), The link points to https://wikidata.beta.wmflabs.org/wiki/Special:EntityPage/Q500927
- Open the developer console and check the page HTML, find the sameAs definition:
<script type="application/ld+json">{
"@context":"https:\/\/schema.org",
"@type":"Article",
"name":"World",
"url":"https:\/\/en.wikipedia.beta.wmflabs.org\/wiki\/World",
"sameAs":"http:\/\/www.wikidata.org\/entity\/Q500927",
"mainEntity":"http:\/\/www.wikidata.org\/entity\/Q500927",
"author":{
"@type":"Organization",
"name":"Contributors to Wikimedia projects"
},
"publisher":{

"logo":{
"@type":"ImageObject",

}
},
"datePublished":"2015-11-12T17:16:19Z",
"dateModified":"2017-03-21T20:42:10Z",

"headline":"This world is a planet where a society of people has formed."
}</script>As you see in the attached script tag, both sameAs and mainEntity point to the www.wikidata.org passing the beta-cluster Q500927 identifier.
