Schema.org: Where did that come from!
2 likes1,717 views
This document summarizes the origins and development of Schema.org. It began as an effort by Tim Berners-Lee in 1989 to conceive of the World Wide Web. Later developments included the semantic web in 2001 and linked open data in 2009. Schema.org was introduced in 2011 as a joint effort between Google, Bing, Yahoo, and Yandex to create a common set of schemas for structured data on web pages. It has since grown significantly, with over 12 million websites now using Schema.org markup and over 500 types and 800 properties defined. Various communities like libraries have also influenced Schema.org through extensions and standards like LRMI.
