Do you provide CAPE-OPEN interfaces ?
The CAPE-OPEN standards unify interfaces between process modelling software components for chemical processes; they are supported and maintained by CO-LaN (the CAPE-OPEN Laboratories Network), a neutral industry and academic association.
The CAPE-OPEN effort really aims at integrating simulation environments, unit operation models and physical property packages from different vendors on the Windows desktop.
At the moment LIBPF does not provide CAPE-OPEN interfaces. What is planned for version 1.0 is a CAPE-OPEN interface for plugging in external thermo models, see the LIBPF roadmap.
Although we believe CAPE-OPEN standards are the way to go for CAPE (Computer Aided Process Engineerig), they were not considered right from the start in the design of LIBPF because one of the design requirements of the library was providing a small, portable process models. Furthermore the innovative approach of LIBPF to process flowsheet simulation just does not fit in the CAPE-OPEN framework.
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), simular to what happened to OPC-DA which recently gave way to OPC-UA (Unified Architecture).
