Use of CASes with sofaURI?

[Richard Eckart de Castilho]

Hi there,

does somebody have an example of how to work with CASes that where the sofa 
data is not set using setDocumentText() but rather using setSofaDataURI(...)?   
      

It looks like the CAS text is then not accessible via the usual means:

        CAS cas = CasCreationUtils.createCas((TypeSystemDescription) null, 
null, null);
        cas.setSofaDataURI("https://www.apache.org/licenses/LICENSE-2.0.txt";, 
"text/plain");
        CasIOUtils.save(cas, System.out, SerialFormat.XMI);
        System.out.println(cas.getDocumentText()); // -> prints "null"
        System.out.println(cas.getSofaDataString()); // -> prints "null"

Apparently, one needs to call getSofaDataStream() - but even after calling 
that, getDocumentAnnotation().getCoveredText() returns null.

So how is one expected to work with CASes that are using this data URI concept?

Cheers,
