I meant: please let's publish some of those other grammar formats as part of this WD. I gather your +1 is to a different idea. I suppose it's not 100% critical to include other grammar formats in the WD, but it seems odd to ask people to cut-and-paste the grammar rather than having a machine consume it directly as source code from the WD. > + the JavaCC file. > > I've started a section: > "Grammars and Parsers for SPARQL" > on the > http://esw.w3.org/topic/SparqlImplementations > page because there are other grammars in the works as well (e.g. Ivan's for rdflib). That's also useful. Do you still have the bison, yacc, and perl-based parsers that you got from Yacker? If so, please mail them to me with a copy to www-archive and I'll add links from SparqlImplementations. > > And turtle, if it's not much trouble. > And an additional +1 to Turtle. > > Andy -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E
