SEEK

We need a mechanism to type input and output parameters in workflows, and to
type data items that are bound to workflows. These types include simple types
and semantic types as discussed at the May 2003 SEEK meeting. MoML has a type
property that is used for simple storage type declarations for ports. We need
to determine if we will be adding a one or more new properties to accomodate XSD
data types and semantic types, or if we can overload the MoML type property. It
is important that this typing system be compatible with WSDL.

To close this bug, please produce:
1) A proposed mechanism for binding qualified type names to ports in an
analytical step
2) A proposed serialization syntax for (1)
3) A modified XSD schema or other document showing the modified MoML or other
language for (2)
