The Initiative Learn More Consume

Launched on June 2, 2011, Schema.org is an initiative Bing, Google and Yahoo! to provide a vocabulary (a collection of concepts and their properties) to be used by web masters to markup web content in ways recognized by major search providers. Search engines will rely on this markup to improve the display of search results, making it easier for people to find the right pages they search for.

While creating Schema.org markup from plain HTML might be painful for beginners and time consuming for everybody, this wiki will help you to easy get Schema.org markup for the most used concepts of Schema.org.

Extracting Semantic Annotations

Typically, applications need to extract semantic annotations from the web pages and use them to perform artificial reasoning.

Microdata2RDF Service

Microdata extractor is a REST web service to extract RDF data from Microdata annotations and provide the semantic information as N-Triples, N3 and JSON. The service conforms with the Microdata2RDF specification at W3C, but the generation algorithm may be different from the one proposed by the specification. The service is powered by node.js and uses jsdom library.
