Hi all, I've been reading draft DFDL spec and scoping doc, and playing around a little with a prototype implementation of an event-based DFDL processor. Unfortunately my time has been limited because the effort has not been scheduled here at EPCC. The general idea is to first generate an internal representation of a DFDL schema. This object model should be easier to work with than a DOM Document and will provide access to the context within scope for each element of the object model, including the supported conversions. For a read scenario, an instance of this object model can be traversed while the underlying data stream is processed into a sequence of DFDL events. At the moment the proto-type supports the example given in section 12.2 of the scoping document. A push-parse is currently implemented, though a pull-parse should also be possible. I'm sorry for regularly missing the telcons. I was away for a while getting married and honeymooning, then got stuck in a meeting on Wednesday. Next week I'm teaching at the grid summer school, but I hope to resume some DFDL work the week after that. Looking forward to seeing developments in the new specification document. Cheers, Tom
