This depends partly on what you consider "finished" to mean. I produced 
the document in question partly to assist me in the process of building 
the parser/validator and partly in response to a request from the WG. In 
terms of a *rough* description of how one might build a 
parser/validator, I'd consider it pretty much finished.

However, there are a number of quite crucial aspects that it doesn't 
address -- for example how one handles anonymous individuals and 
individual facts concerning them. Producing a document that really 
covers this in detail (and making sure it was right) would be probably 
just as much work again.

My initial inclination is not to pursue this right now -- in some ways 
building the RDF parser was for me a "necessary evil" :-) which then 
allowed me to do some other stuff, rather than it being a core activity. 
  However, if it's considered to be *really* important, then I might be 
persuaded. Of course if the current document is considered sufficient, 
then I'm more than happy to do some simple tidying up and for it to be 
included in other stuff/published as working note/nailed to the door of 
the kirk etc...

Incidentally, the thanks here are really to Peter, as it was a 
discussion with him at the DL workshop that crystallised ideas in my 
mind for tackling the bnode stuff. I have also made a number of minor 
updates to the document to reflect some additional comments Peter made.
