[dfdl-wg] DFDL WG call 2006-06-28

[Mike Beckerle]

Attendees: Geoff Judd, Bob McGrath, Mike Beckerle

We discussed the "consolidated" document, w.r.t. folding in missing 
sections.

We discussed that updating the sections on  conversions, and extensions 
should wait for current work on conversions and groups to draw some 
conclusion. 

We discussed that the arrays material needs to be segmented to fit the 
outline of basic material vs. detailed material.  Bob said he'll try to do 
that or at least make notes in it about areas where there is uncertainty 
about where a section should go. 

Geoff will check with Steve Hanson about folding in the properties 
document. The latest IBM-internal version of this document needs at least 
to be stripped of IBM-specific material before we publish it to the WG. 

The big properties list will again raise the issue of how to segment into 
core + extra packages, and what is core and what is extension. That's ok, 
we need to have that discussion. There are several sections such as the 
work Geoff lead on optionals/default/nullable, etc. and also on wildcard 
behavior that need to get folded in, but without the properties to refer 
to it's very unclear how to put these sections in.  They are in some sense 
about the meanings of specific groups of properties and their 
interactions.

Question for the group: does anyone have anything written about layering 
and hidden layers that is newer than last september's "draft" document. 
There was material there about layering that I did not bring forward into 
the "consolidated" document yet because I wasn't sure if it was still 
current or not..
