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