Yes, +1 for option 3; otherwise we would need to define the semantics of 
combinations of the conflict resolution strategies, e.g. a kind of 
priority between the different strategies or a module concept where the 
conflict resolutions is local to the imported rule set. However, there are 
not many rule systems which implement such distributed scoped modules.

All, 

It occured to me that we did not implement, in PRD, the resolution from 
F2F12 [1] about importing RIF documents... 

I see four ways to implement that resolution in PRD: 
1. restrict the import to Core documents (only PRD documents that are also 
Core documents can have imports, and they can import only other Core 
documents); 
2. retrict the import to PRD documents with implicit conflict resolution 
strategies (or explicit rif:forwardChaining conflict resolution strategy, 
which is the same) and they can import only other PRD documents with the 
same restriction; 
3. restrict the import to the case where the importing and imported 
documents are all associated with the same conflict resolution strategy; 
4. allowing import of other PRD documents without restriction. 

I propose to exclude option 4 as to ocomplex: we have no idea of the 
semantics; I also propose that we exclude options 1 and 2 as overly 
restrictive, and that we implement option 3. We have only one conflict 
resolution strategy that is specified normatively, anyway; so, it might 
seem that option 3 is the same as option 2; except that it makes extension 
to other conflict resolution strategies easy (or so it seems)... 

What do you think? 

I drafted a section on documents and imports in RIF-PRD [2] according to 
option 3. I have, still, to update the section 8.5 accordingly. 

Please, read and react.
