This one has been resurrected from the collection of post-crash blogs:

How is it possible to connect metadata/column information to Word documents stored in a WSS 3.0 library so that it is synchronised both ways??

Also referenced in the MS Office Word Team blog adding links between Word & MOSS metadata/columns is simple enough to do, but one thing appears to be missing....
Easily implemented for custom metadata and a few defaults, however 'Version' (as in the version number created by doc libs, both minor & major) doesn't seem to be available? Only Revision number which isn't the same. Or am I missing something?

Surely this is one of the more important columns that users may wish to include in a document header. How can this be added??

Finally, after trawling through endless forums & posts I find a blog by Joerg Sinemus describing exactly what I want to achieve. Though by no means a simple solution: http://blogs.msdn.com/joerg_sinemus/archive/2007/01/26/wss-version-number-in-the-word-2003-document.aspx

A great post, but surely there is an easier way to do this in MOSS / Word??

The bigger questions is perhaps: why on earth wasn't this feature included in the WSS 3.0/Word integration options by default??!!! After all, once a document is in library you can connect any custom metadata using the Quick Parts as well as some defaults. So why not Version?? it's possibly one of the most often used items in word headers.

So was this a serious lack of foresight on the part of the MOSS development team? or just too complicated to get into this release?
