•OGSI models portType inheritance using
gwsdl:portType
–Modeled like W3C proposal for interface inheritance
–GGF commits to moving to WSDL 1.2 when W3C is
finished
•SDs are inherited down a gwsdl:portType inheritance hierarchy
•Overloading is handled like operations
–SDEs are namespace qualified
–Duplicate SDEs are elided
•Values can be associated with (certain) SD
Declarations
–Only SDEs where mutability=“static”
–These are like “class constants”
–Values are aggregated down a portType inheritance
hierarchy
