aboutBNode, valueBNode relations?

[bblfish]

Feature request: One may want to generate bnode subjects and objects using information in the table, which could then be forgotten about once the graph is finished.

the :aboutBNode and :valueBNode relations would allow one to specify bnode patterns to do this.

Along similar lines I was hoping I could find a way to build up a description of a csv table without needing to resort to building URLs, so that I could specify a csv schema in two parts:

• a purely schematic part
• a instance level part where nodes could be named

So for example for the table

Id,Name,DoB,Sex,mother
1,Linus,02-07-2016,male,4
2,Oliver,02-07-2016,male,4
3,Anaïs,10-09-2014,female,4
4,Gordana,30-05-1982,female,

I would like to be able to get either

[]  <#Name> "Anaïs" ;
    <#DoB> "2014-09-10"^^xsd:date ;
    <#Id> 3 ;
    <#Sex> "female" ;
    <#mother> [ <#Id>  4 ] .

with <#Id> as an owl:InverseFunctionalProperty. I could not find a way to do that with virtual columns.

The other way would be to get something like

_:b3  <#Name> "Anaïs" ;
    <#DoB> "2014-09-10"^^xsd:date ;
    <#Id> 3 ;
    <#Sex> "female" ;
    <#mother> _:b4 .

but in a way that would make it transparent how they were related. Here I was hoping that primary key and foreign keys could help, but I think they need the fields to be URLs. At least this did not give me what I was hoping for.
