Summary

0030844: Data Exchange - Support import from and export to stream for data exchange interface

Description

OCAF has already support stream interface. This is definitely a great design. While it's lacking support for data exchange interface such as STEP, IGES, STL, VRML. Why we need stream support for such case? the first reason is that user has higher level control on file. For example, on UWP application, user don't have permission to accessing file directly outside sandbox with traditional file operation API. To conquer this issue, user can use the windows UWP API to open and save file by using bridge stream interface. There may be other benefit with the stream interface.
