(demonstration of embedding arbitrary data from Wikidata)

Since Kolkata is item Q1348 in Wikidata, and since "population" is property P1082 in Wikidata, I can tell you that, according to Wikidata, the population of Kolkata is ৪৪,৯৬,৬৯৪.

That number in bold up there was produced with the following wikicode: {{#property:P1082|from=Q1348}}.

Likewise, since Rabindranath Tagore is item Q7241 in Wikidata, and since "occupation" is property P106 and "date of birth" is property P569 and "place of birth" is property P19 in Wikidata, I can tell you that Tagore was born in কলকাতা, on ৭ মে 1861, and is a চিত্রকর, কবি, সুরকার, নাট্যকার, প্রাবন্ধিক, দার্শনিক, শিল্পী, লেখক, গীতিকার, গীতিরচয়িতা, সঙ্গীতশিল্পী, চলচ্চিত্র পরিচালক, মুক্তিযোদ্ধা.
