To: RIF WG <public-rif-wg@w3.org>

This is an incomplete attempt to sketch out an example goal/csf/requirement 
hierarchy to help me at least see the wood for the trees.

This is not "right", just preliminary musings, so it can't go into the 
Design Constraints page (violates the stated ground rules for that). Posted 
in its current highly preliminary state in case it is a useful seed.

** Goals
G1 Enable effective interchange of rules between existing rule systems
G2 Widespread adoption
G3 Foundation for a semantic web rule language

** Breakdown

G1 Enable effective interchange of rules between existing rule systems
  C1.1 Able to express the main features of relevant commercial rule systems
    R1.1.1 Support for production rule languages

  C1.2 Interchanges can be meaning preserving
    R1.2.1 RIF semantics is clear and precise
    R1.2.2 RIF semantics is compatible with the rule languages to be

  C1.3 Cohesive, sufficiently few RIF dialects that there is useful

G2 Widespread adoption
  C2.1 Low cost of entry
   R2.1.1 comprehensible and succinct specification documents
   R2.1.2 (auxiliary) human readable syntax

  C2.2 Ease of "implementation"
   R2.2.1 Sufficiently expressive that RLi -> RIFdialect is easy
   R2.2.2 Sufficiently inexpressive that RIFdialect -> RLj is easy
   R2.2.3 modest number of RIF dialects

  C2.3 Can be extended to handle interchange between languages not
       explicitly considered by WG
   R2.3.1 Extensibility mechanism

G3 Foundation for a semantic web rule language
  C3.1 Webized
   R3.1.1 predicates, instance objects etc designated by URIs

  C3.2 Compatible with RDF
   R3.2.1 RIF core must be able to accept RDF triples as data
   R3.2.2 RIF core must be able to express RDF deduction rules

  C3.3 Compatible with OWL
   R3.3.1 RIF Standard inference and OWL inference can be combined in a
           well-defined fashion

  C3.4 Compatible with SPARQL
   R3.4.1 RIF Standard rules can query SPARQL data sources
   R3.4.2 RIF Standard include SPARQL-compatible named graph support?
