The OWL API at sourceforge ( http://sourceforge.net/projects/owlapi ) has an Antrl based OWL Abstract Syntax parser. Here are the files for the antlr parser and lexer: http://cvs.sourceforge.net/viewcvs.py/owlapi/owl/abstractparser/grammar/abstract-owl.g?rev=1.4&view=auto http://cvs.sourceforge.net/viewcvs.py/owlapi/owl/abstractparser/grammar/lexer.g?rev=1.3&view=auto It shouldn't be too hard to adapt these to use the Jena API...

I believe it might be a good idea to support the OWL Abstract Syntax ( http://www.w3c.org/TR/owl-absyn/syntax.html ), as it is easier to type and read than N3. Unfortunately, Jena does not have an abstract syntax parser :( So we probably should write our own parser. My own preference is to use JavaCC because I already know how to use it, but the Antlr is already a part of Jena (and it is in our CVS!) so it might be better to just use Antlr. Here is the Antlr home page: http://www.antlr.org/ It seems to be pretty good. And the documentation is much better than JavaCC's... What are your thoughts on this? -- Gerardo Horvilleur ma...@mu... |

I like the idea, but if you are thinking in a disdributed system, with = peer to peer feauteres. I will like propose an alternative. I have been = working on a project of my own that I have called "Object Oriented Distributed Virtual Systems" OODVS, and I have varios interesting results and = features ready to use. One of the key techonologies of Jini is RMI unfortunatly = RMI has not implemented some very importan features for distributed systems = like UDP BroadCasting and UDP Multicasting. Several years ago, I get tired = of waiting and I made a cleanroom implentecion of a comunication stack, = that it also implemtens various services that can be compared with jini. =20 Now a days I have a lot of documentation to do. But I have some = examples, an varios automated test that can ilustrate very well the feautures of my stack.=20 I would be very pleased to show you de the demos and give you code to = try it =3D) Regards =3D) PD please for give poor my english. -----Original Message----- From: Gerardo Horvilleur [mailto:ma...@pr...]=20 Sent: Sunday, June 27, 2004 2:09 AM Cc: edivargas; Elmer Garduno; Gustavo De la Cruz Tovar; Diego Ernesto Malpica Chauvet; Claudio Horvilleur; Emilio Osorio; Francisco Castrillo Subject: Re: Jini Para que sea mas facil platicar de estas cosas di de alta un mailing = list en sourceforge: http://lists.sourceforge.net/mailman/listinfo/javaowl-devel Nada mas acuerdense de poner todo lo que escriban en ingles para que nos puedan entender en otros paises!
