Here's one technique a parser could follow: When an explicitly named bnode is found, check if its name starts '_:bn'. If not, use it verbatim. But if so, replace the '_:bn' with '_:bnbn'. When a name is needed for an implicit bnode, give it one starting '_:bn' followed by numbers. You should find that this can never produce a collision. Of course if means that in some cases, explicitly named blank nodes in the input RDFa have different names in the output graph. But that's OK - RDF doesn't assign any meanings to the names of blank nodes. -- Toby A Inkster <mailto:mail@tobyinkster.co.uk> <http://tobyinkster.co.uk>Received on Saturday, 14 November 2009 19:37:19 UTC
