Re: RFP: CompoundStorage document

Hi Dietmar,

I believe that Bonobo is either the wrong way to solve this problem or 
solves this problem on a different level than I'd like to see it solved at. 
In my mind, these are functionally equivalent statements ;-)

What I'm looking for is a lower-level class heirarchy that Bonobo can build 
on top of, if it so chooses. You could create monikers for these different 
proposed storage classes. If you've already taken the time to map the Bonobo 
storage interface on top of disparate libraries (libefs and libole2), why 
not take the time to map the Bonobo storage inteface back on top of my 
proposed unified class(es)? The mapping from my proposed class to the Bonobo 
storage interface would seem to be fairly straightforward. It also seems to 
me that the interfaces could be practically identical and that we could grab 
the existing OLE2 and EFS code and push it upward into my proposed class. 
This way our classes and libraries are available to more people and 
platforms and still wholly & easily accessible to Bonobo. This inclusionary 
RFP seems to make sense, at least to me. You are, of course, free to 
disagree.

If my RFP is rejected by the GNOME community (nb: your suggestion will 
severely break my application), I'm prepared to go and invent this wheel 
nevertheless.

Cheers,
Dom

Men are incapable of using sex to get what they want. Sex IS what men want. 
Sex is not the answer.  Sex is the question.  "Yes" is the answer.
