[DDI-ADG] Preparing for Friday's call

[Mary Vardigan]

First, I want to apologize for setting up the call at a time when
Europeans can't participate. Will do better next time.
 
Second, I have been struggling with how to evaluate the parts of the
schema that our group developed. I have found it useful to look through
the PDF document that was created from XMLSpy and is found on the
sourceforge site at:
 
http://sourceforge.net/project/showfiles.php?group_id=100852&package_id=
108463
 
and is called:
 
DDI30_2006-03-24_xmlspy_pdf.zip
<http://prdownloads.sourceforge.net/ddi-alliance/DDI30_2006-03-24_xmlspy
_pdf.zip?download>  
 
It's 899 pages but has some very helpful diagrams. 
 
Also, helpful is this page:
 
http://ddi-alliance.sourceforge.net/documentation/3.0/2006-03-24/xsddoc/
 
Click on the reusable module link to see the geography and time elements
and on the physicalproduct/ncubes submodules to see the nCube
structures. 
 
Also helpful is Pascal's page at:
http://www.opendatafoundation.org/infocenter/index.jsp
 
Expand the DDI "book" on the left and click on Modules.
 
J, can you suggest other things we might look at and what we should be
paying attention to? For me and I imagine for many of us, the schema is
much harder to decipher than the DTD was, so I tend to get confused
easily. 
 
Related to this, I was wondering how important you think it is that we
all "understand" schema. Might there be some way we could provide the
Expert Committee a brief tutorial in understanding how schemas work and
how things fit together? Ideally, this would take place before the DDI
meeting in May (through a Webcast, possibly?), but if that can't happen,
should we think about providing some of this basic information at the
meeting? Not everyone will be going to the workshop on Tuesday.
 
Interested to hear what you all are thinking...
