I will look at these schemas. Can you react to my previous message sent a 
few days ago titled "Flat schema for PRD". A think we can keep a flat 
schema to ease the work today and have more time to do a refactoring in 
the future, along with BLD.


I was developing a Java tool to parse the RIF PRD schema and validate the 
instance documents. I had some problems to deal with the "redefines" (PRD 
imports Core schema and redefines some elements) inside PRD. 

So I have created a flat PRD schema, by merging the core schema with the 
PRD specific one, then I was able to continue using this schema. I know 
that I had proposed that PRD should include Core, but at this moment I 
have no so much time to spend on this schema, and think that we could keep 
the flat schema for PRD. Note that BLD already have a flat stand-alone 
schema as well. Later on, we can refactor the schemas so that they are 

I just want to let you know and hope that you are fine.

RIF Core and RIF PRD Schema ready
Sent by:

Hi All,
Together with Harold I have updated the RIF Core Schema:

I have then reengineered the RIF PRD Schema and finalized it:

It is a direct extension of the RIF Core Schema and validates correctly. 
I have also fixed some bugs in the EBNF with respect to non-deterministic 
content models.
Gary, Changai, can you please check.
