What is Schema.org
?This site provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages.A shared markup vocabulary makes it easier for webmasters to decide on a markup schema and get the maximum benefit for their efforts. So, in the spirit of sitemaps.org
, search engines have come together to provide a shared collection of schemas that webmasters can use.If we are creating repositories of data on the Web, such as Web Observatories, then the addition of this kind metadata can make it much easier to discover other sources of data and other observatories with whom data could be shared /exchanged .
