The CAPE-OPEN standards unify interfaces between process modeling software components for chemical processes; they are supported and maintained by CO-LaN (the CAPE-OPEN Laboratories Network), a neutral industry and academic association.

More exactly the CAPE-OPEN effort aims at integrating simulation environments, unit operation models and physical property packages from different vendors on the Windows desktop.

Although we believe CAPE-OPEN standards are the way to go for CAPE (Computer Aided Process Engineering), they do not fit the design requirements of the LIBPF library: to make small, portable process models possible with a lean, flexible approach.

Finally, CAPE-OPEN is based on COM, an API which dates back from 1993. There is an unsatisfied need for an evolution of CAPE-OPEN from COM/CORBA to .NET or even better to a platform-independent SOA (Service Oriented Architecture), similar to what happened to OPC-DA which recently gave way to OPC-UA (Unified Architecture).
