Luis, Eliot - this is what Graham and I have come up with as our statement
of what we will deliver and how it relates to the work of the other
subgroups. Do you have any comments or suggested modifications? We have to
deliver this to the Authoring Group by 3 September, so please respond
promptly if you do have anything to add/subtract/change.


DELIVERABLES:

1) Completion of 13250 Conceptual Model
	a) Conceptual model implicit in 13250 (expressed in UML)
	b) Property Set for that conceptual model (expressed in SGML
conforming to HyTime property set DTD, and expressed in UML)
	c) 13250 Syntax Constructs : (expressed as a DTD (the ISO 13250 DTD)
and expressed in UML
	d) Formal mappings between a, b and c (expressed in UML)

2) XTM Conceptual Model 
	a) Conceptual Model of XTM (expressed in UML)
	b) Property Set for that conceptual model (expressed in SGML
conforming to HyTime property set DTD, and expressed in UML)
	c) XTM Syntax Constructs (expressed as a DTD (this is the DTD that
the Interchange Syntax Subgroup will produce) and expressed in UML)
	d) Formal mappings between a, b and c, (expressed in UML)
	e) Description of the differences between 2a and 1a
	f) Justification of those differences (based on clarification or
resolution of ambiguities in 13250, or based on Use Cases that suggest
enhancements or simplifications to the 13250 model

3) Description of relationship between XTM conceptual model and RDF
conceptual model.
	a) UML representation of RDF Conceptual Model (expressed in UML)
	b) Fomal mapping between 3a and 2a (expressed in UML)


RELATION TO OTHER SUBGROUPS

1) Interchange Syntax Subgroup
	a) Dependency: To allow us to do 2c, the ISS needs to inform us of
its decisions regarding syntax constructs
	b) Impact: 2d might reveal the need to enhance or modify the
syntactic constructs. They must be formally mappable to the conceptual
model.
	
2) Use Cases Group
	a) Dependency: Some use cases may dictate simplifications or
enhancements to the conceptual model
	b) Impact: The conceptual model may have power that suggests further
use cases
