[DFDL-WG] DFDL infoset

Wed Oct 31 11:21:15 CDT 2007

Simon - there's also a requirement to get at the underlying metadata for 
an infoset item, should an implementation wish to do so. SCD has been 
suggested as a good way to do this, you may want to look at this prior to 
the call (http://www.w3.org/TR/xmlschema-ref/). Means each infoset item 
would have a (eg) [metadata] member too.

Regards, Steve

[DFDL-WG] DFDL infoset

Good afternoon.

Steve sent me the infoset draft for review. I considered it along with the 
embedded comments, and felt a slightly different approach might make our 
intention clearer and allow more rigour with fewer words. I offer this 
alternative starting point for further discussion and refinement; if it 
doesn't find favour I'll go back and refine the original.

Hope this helps,
 Simon

Hi Simon - draft DFDL infoset attached - doesn't cover the repeating 
groups 'wrinkle' discussed on the call.

Re: DFDL infoset - please reviewLink

It's ok for now. We either need to explain an "array info item" or be 
comfortanble that array vs. scalar is explained elsewhere. 

"belongs to an array" should be "belongs to an array of information items" 
I think so as to make it clearer that there isn't a special "array", but 
rather these are ... just arrays of information items.

Thanks Mike. 

Regarding your array comment, you look to be saying that while it begs the 
question about an array info item, we are probably ok without one. 
Correct?  I used Sandy's phrase  "belongs to an array" rather than "is an 
array" - perhaps the latter is better?
