[Rdfapi-php-interest] bug in generation of blank nodes...

[Gunnar G. <ggr...@cs...>]

As the attached file shows, there is something strange going on with 
generation of BlankNodes when combining two models... The code in 
Model::_addStatementFromAnotherModel correctly identifies colliding 
nodes, but then generates new node IDs that also collide... :(

I've fixed this with a global variable keeping track of BNodeIDs, which 
can be used in Model::getUniqueResourceURI, and 
RDFParser::_generate_anonymous_uri ...

It's not very pretty, but it works, and I can add it to CVS if people 
want...
