Description

I wonder if it is possible to add a new RDFa extractor which uses java-rdfa [1].

java-rdfa is (according to its creator, Damian Steer ) "the cruftiest RDFa parser in the world" (and he is probably right!). java-rdfa is currently passing all conformance tests for XHTML, and the HTML 4 and 5 tests with one exception [2]. An online service|demo [3] is also available. java-rdfa, as far as I understand, is currently licensed with a BSD license. The Maven artifacts are available in the Maven central repository [4].

From my little understanding of Any23, in order to do this one needs to implement BlindExtractor (which extends Extractor<URI>) and ContentExtractor (which extends Extractor<InputStream>).
