Re: FW: FpML-AWG View generation syntax

[matthew.d.rawlings@xxxxxxxxxxxx]

I suggest the document adopts standard
modelling terminology:

1. The 'master schema' is a Conceptual Model. Its perspective or view is the global context.
2. Each 'view' is a Context and its resulting schema is a Logical Model. Its perspective or view is a local context.

It is common in conceptual modelling
to leave the cardinality/multiplicity of Properties (elements, attributes,
references) undefined. The cardinality is added in during the transformation
from the Conceptual Model to the Logical Model - i.e. the 'view' generation
process adds cardinalities for the first time. This for example is what
ISO20022 does in the generation of the local views (Message Layer) from
its global view (Business Layer).

It is also common in conceptual modelling
to localize names of classes and properties in the transformation to the
Logical Model (local context views). I suggest that as this is such a common
operation this be supported explicitly.

Attached is a first cut of a document describing the FpML 5.0 view
generation syntax.  I think it needs some work on formatting, and
perhaps
some additional clarifying text.  Also, in doing this I realized that
there
may be some slight inconsistencies that could be cleaned up.



Comments/suggestions welcome.
