run

public void run(ExtractionParameters extractionParameters,
                ExtractionContext extractionContext,
                Document in,
                ExtractionResult out)
         throws IOException,
                ExtractionException

This extraction performs the Microdata to RDF conversion algorithm. A slight modification of the specification algorithm has been introduced to avoid performing actions 5.2.1, 5.2.2, 5.2.3, 5.2.4 if step 5.2.6 doesn't detect any Microdata.

Specified by:

run in interface Extractor<Document>

Parameters:

extractionParameters - the parameters to be applied during the extraction.

extractionContext - The document context.

in - The extractor input data.

out - the collector for the extracted data.

Throws:

IOException - On error while reading from the input stream.

ExtractionException - On other error, such as parse errors.
