Methods & Tools SIG held a conference call from 5 pm till 6:10 pm Central European Time.

Participants: Bill BARRETT (U.S. Environmental Protection Agency), Jasper van BATEN (AmsterCHEM), Michael HLAVINKA (Bryan Research & Engineering), Michel PONS

Agenda: progress on the interface description via UML, diagrams and text..

Outcome: Worked especially on the requirement imposed to the PME for its Unit Operations and streams as well on requirement imposed to Flowsheet Monitoring Component regarding prevention of any call to methods modifying objects presented by the PME to the FMC in its Unit Operation Collection and Stream Collections. Needs still to revise wording in relevant requirements (section 2.2) to be sure the readers will understand what is made mandatory. UML interface diagrams for Unit Operation Collection and Stream Collections were revised so that the mandatory and non-mandatory interfaces shown are consistent with text (section 3.5.1). Version 1.49 of the Flowsheet Monitoring interface specification is the result of that meeting and is accessible to CO-LaN members with the shared drive of the “CAPE-OPEN IDL” project repository.
