Invalid output format "alignment"

[Franck Michel]

Hi all,

I'm using Silk single machine 2.7.1, and I get a somehow curious answer when using the output format "alignment":

Exception in thread "main" java.lang.IllegalArgumentException: requirement failed: Invalid format 'alignment'. Supported formats are: 'RDF/XML', 'N-Triples', 'N-Quads', 'Turtle'
    at scala.Predef$.require(Predef.scala:219)
    at org.silkframework.plugins.dataset.rdf.FileDataset.<init>(FileDataset.scala:37)

Besides the message seems to talk about input datasets, which in my case have format "TURTLE".

Here is my outputs section:

    <Outputs>
        <Output type="file" minConfidence="0.95" >
            <Param name="file" value="equality_reference_with_date_accept.nt"/>
            <Param name="format" value="N-Triples"/>
        </Output>
        <Output type="file" maxConfidence="0.95" >
            <Param name="file" value="equality_reference_with_date_verify.xml"/>
            <Param name="format" value="alignment"/>
        </Output>
    </Outputs>

Is there something I'm getting wrong?

Is it a limitation of the single machine version ?

Thanks in advance for your help,
   Franck.
