Andy Seaborne resolved JENA-1477.
---------------------------------
    Resolution: Done

> Updating from Jena 2.12 to Jena 3.0.1 produces different RDF/XML output IF 
> ARQ is loaded

>                 Key: JENA-1477
>                 URL: https://issues.apache.org/jira/browse/JENA-1477
>             Project: Apache Jena
>          Issue Type: Question
>          Components: RDF/XML, RIOT
>    Affects Versions: Jena 3.0.1
>         Environment: Jena 3.0.1
>            Reporter: Andrew Berezovskyi
>            Priority: Minor
>
> We are in the process of a Jena 2>3 transition in Eclipse Lyo and discovered 
> the following: if the ARQ is used in the application, then the typed node 
> elements will be used by default, which did not occur in Jena 2. It causes 
> problems for some legacy apps that rely on Lyo.
> We were able to eliminate this behaviour by calling the static method
> RDFWriterFImpl.alternative(null);
> Technically, this ensures that the 
> 'org.apache.jena.rdfxml.xmloutput.impl.Basic' implementation is not getting 
> substituted for the 'org.apache.jena.riot.adapters.RDFWriterRIOT'.
> Questions:
>  # Is it the best way to ensure backwards compatibility of the RDF/XML output 
> when moving from Jena 2>3?
>  # Is there any way to control the RIOT writer to produce XML w/o typed node 
> elements so that we can avoid resetting the alternative writer?
>  # (if you have some extra time) What purpose do alternative writers serve? 
> What is the difference between the writers in the respective packages as the 
> two writers above?
