We could list the common ones (Gary already listed some in his eMail and there a many other proposal for conflict resolution, e.g. based defeasible , argumentation etc.  ). 

But shall we really define a default one??? That might be easily misunderstood as being normative, i.e. a RIF PRD compliant production rule system must at least support the default semantics for conflict resolution. 

That is certainly not what we want, or?

We could simply say there is a function which resolve certain conflicts in our operational semantics without being specific about it (i.e. refer to the different strategies which are possible).

ISSUE-64 (PICK): Conflict resolution strategies to be covered by PRD? [PRD ]

http://www.w3.org/2005/rules/wg/track/issues/

Raised by: Christian de Sainte Marie
On product: PRD 

- Some PR languages permit fairly complex conflict resolution strategies: what conflict resolution strategies should PRD cover?
- What combinations?
- Should there be a default strategy, and, if yes: which one?
- How to notify the intended strategy or combination to the consumer?
- OMG PRR does not identify specific conflict resolution strategies, but two operation modes: forward chaining and sequential (but the description of the semantics makes the forward chaining mode explicitely dependent on a conflict resolution strategy that is not defined further). Should PRD cover some form of a sequential mode and, if yes: which?
