my action from July 11 RIF telecon

<scribe>  ACTION: pfps will describe loophole he sees in the semantics
[recorded in http://www.w3.org/2006/07/11-rif-minutes.html#action11]


I see two loopholes in the mapping from rule conditions to the Conditions
in http://www.w3.org/2005/rules/wg/wiki/Extensible_Design.

1/ There are multiple potential semantics in the Extensible Design.  Worse,
   the different semantics are provided only by very vague references.
   This leaves open the possibility of using the syntax of the Extensible
   Design, but providing a special semantics that might, for example,
   interpret "And" as disjunction.

   Yes, this example of modifying the semantics is particulary silly, but
   there are indeed useful rule languages where the order of conjuncts
   matters.  How can such deviant semantics be accommodated while
   disallowing silly deviations?

2/ The calls for mappings have not provided any semantic requirements for
   the mappings.  This leaves open the possiblity that the mapping does not
   respect any semantics.  For example, the mapping might just map
   disjunctions into CONJ.

   Yes, there has been discussion on what the semantic requirements should
   be, but there has not yet been consensus.  See
   http://lists.w3.org/Archives/Public/public-rif-wg/2006Jun/0101.html for
   one possible way to go.
