MCE Best Practises - draft for review

[Chris Rae]

Hi all – attached is an updated draft of this section. I’ve left track-changes on so that we can easily see what changed between the WG4 meeting and now.

Chris,

Good start!  

First, I think that we should cover foreign OPC parts.  Advantages: 
applications unaware of such foreign OPC parts preserve them, as 
long as they are referenced by relationships.  Disadvantages:  
(1) unaware applications discard them if they are not referenced by 
relationships.  (2) since such foreign parts augument certain points within 
existing parts, we have to specify which point in which part is augmented.

Second, in Document Interoperability Initiative event in 2009, Microsoft 
explained extensions of OOXML.  Each presentation provides 
very useful information.   It shows which extension is done by 
using which mechanism.  One option is a combination of a foreign OPC part 
and MCE!  Moreover, I vaguely remember that old EXCEL  rewrites 
application-defined extension elements beyond them, when rows or columns are 
deleted or inserted.

The link to the presentation materials of this event is:

  https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices

Unfortunately, the link to the Excel extension documentation is broken.
It should cover rewriting app-defined extension elements.


Third, an Assembla wiki (https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices)
summarizes discussions in the past.  "Extensibiity and ISO/IEC 29500" by Microsoft (WG4 N0223), 
which is now available at the WG4 E-Committee page is also very useful. 

Regards,
Makoto

Hi all - I'm back from paternity leave and have been reminded that I have action items for SC34. This is probably the largest one - attached is my first draft of some informative text regarding MCE best practises. I began with text of Murata-san's and expanded upon it with examples. It's written in a very informative "primer" style which I thought best suited the subject matter.

We should probably talk about it in more detail in London next week, but I wanted to give everyone a chance to read it before then. Although they wouldn't be included in the standard itself, I've attached a zip file containing the samples included in my document, should anyone wish to experiment with them.

See most of you next week,

Chris
