Please, if anyone has a working Fuseki assembler file that includes both Lucene 
indexing and a reasoner, would you be willing to share it. It seems that I can 
have either/or but can't seem to get it to do both.

Thanks Dave for the suggestions regarding my second question. I had seen the 
page at https://jena.apache.org/documentation/inference/, but that page shows 
class names and not the URLs that you use in the assembler. I can write a 
little code to call ReasonerRegistry.theRegistry().getAllDescriptions(), but I 
was hoping that the options were listed on a web page. For others with this 
question, the closest I found was this: 
https://jena.apache.org/documentation/javadoc/jena/constant-values.html

But it still isn't clear, from that page, what the differences are between, for 
example:

http://jena.hpl.hp.com/2003/RDFSFBRuleReasoner
http://jena.hpl.hp.com/2003/RDFSExptRuleReasoner

Also for anyone else who encounters this thread during a search, I found a 
possible solution to #3, in the comments of this page (the one that talks about 
<urn:x-arq:UnionGraph>):

Cheers,
Todd

    Maybe someone else can help with that, I find assembler files a little 
    confusing.

    ReasonerRegistry.theRegistry().getAllDescriptions() will give you 
    everything but the most relevant ones are likely to be:
    
    RDFS
       http://jena.hpl.hp.com/2003/RDFSExptRuleReasoner
    
    OWL Micro
       http://jena.hpl.hp.com/2003/OWLMicroFBRuleReasoner
    
    OWL Mini
       http://jena.hpl.hp.com/2003/OWLMiniFBRuleReasoner
    
    OWL
       http://jena.hpl.hp.com/2003/OWLFBRuleReasoner
    
    For description see https://jena.apache.org/documentation/inference/

    I don't think so.
