We have to stay tuned for "N3 formal grammar" as you can see in http://www.w3.org/2000/10/swap/doc/plans.html and in the mean time continue with http://www.w3.org/DesignIssues/OldNotation3Grammar and map the verbs to the this.name and the subject and object to this.partlist.list (I've done tests with a mapping to holds(s, p, o) but that is dramatic :)) best regards, jos -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/ ant...@4c...

Ok, thanks, we are writing a jflex grammar, the idea is to have a N3 scanner and a parser in java and then try to write a js equivalent. The easier the code result the better.
