RDFXML write in plain with properties

Dear all,

I am struggling with the ways to write the RDF

I need to 
- output in file (xml), 
- declare xmlbase and show it in the file, 
- use property "showXmlDeclaration"
- use the "relativeURIs" with "same-document", but want to have "#foo" kind of reference
- have RDXXML_PLAIN output - not nesting

I tried with using RDFWriter to set properties and I could get most of above except the "#foo" and the plain export. I get "foo" without the # independently if the xml base has # at the end or not

If I use RDFDataMgr plain export kind of works, but I cannot set the properties 

Is there some way to combine or use another trick?

Best regards
Chavdar

Hi Andy,

Thank you

I was looking into this, but I was getting the message "Cannot resolve method 'create ' in RDFWriter"

It was due to the import of the RDF writer from rdf.model and not from riot. SO now I can go a step further 😊

Hi Chavdar,

 �

Here's an example of setting properties specific to the RDF/XML writer.

 �

https://github.com/apache/jena/blob/master/jena-arq/src-examples/arq/examples/riot/ExRIOT_RDFXML_WriteProperties.java

 �

RDFFormat.RDFXML_PLAIN wil get you the unnested form.

 �

It's a two step way to define the context which is difefrent for RDF/XML.
