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. More information on endpoint, usage and limitations at: http://getschema.org/microdataextractor/about

RDFa2RDF Service

RDFa extractor is a REST web service to extract RDF data from RDFa Lite annotations and provide the semantic information as N-Triples, N3 and JSON. The service is powered by node.js and uses jsdom library. More information on endpoint, usage and limitations at: http://getschema.org/rdfaliteextractor-about/

The service is also listed at the Semantic Web Initiative wiki page http://www.w3.org/2001/sw/wiki/RDFa_Extractor

What you can do

Solve everyday annotation problems, debate on discussion pages and document your solutions on the wiki. Start concrete discussions helping others to understand: how to use, what to use, where to use and who uses these concepts. Spread the word – blog it, bulletin board it, tell your friends.Write and share tools (link them up on the wiki). Inspire others with what you build.
