(In follow up to my previous mail). I've placed my OCCI ANTLR grammar up on github [1]. There is some brief documentation (presentation here [4] ) and examples on how to get working with the grammar. There are 2 grammars. The first is just the generic grammar with no target language ANTLR actions [2]. The second is the same grammar but with Java-specific target language ANTLR actions [3]. Those actions extract the values the parser encounters and assembles a data structure that can then be queried. This all happens after validation of the text request/response received. The grammar's lexer and parser can be used both in client and service code. For clients, the lexer/parser can be used to read the response from an OCCI server and also validate outbound requests to a service. For services, the lexer/parser can be used to validate the requests from clients, extract values (if using a target specific grammar) and then validate the responses sent back to the clients. Of course, the grammar's lexer/parser is ideal for use in your test suites especially for testing the serialization of your OCCI model to text. You shouldn't worry about deserialisation as that should be the job of the ANTLR grammar - with the relevant ANTLR actions. The grammar and associated code is released under the BSD license so please feel free to fork and use it. I know myself from experience that writing parsers is a PITA and why repeat (DRY!) when you can leverage not just our experience of specifying OCCI but also that of the ANTLR community in creating parser generators! Win! If anyone would like a walkthrough of this stuff, I can do so again at next week's OCCI confcall as I won't be able to participate at Taipei.
