On February 18, 2016, Management Board of CO-LaN approved the public release of a document (Parameter_Errata_1 0_1 022) providing errata and clarifications on the Parameter Common Interface specification.
In particular, this document addresses the effect of various initialization and editing operations on the state of the Parameter Collection so that PMEs will know potential changes to the Parameter Collection that may result from these operations. This clarification is intended to improve the performance of a process simulation application by reducing the number of times the PME iterates through the Parameter Collection to update the state of the Parameter Collection in the PME’s graphical user interface. This document clarifies what are the static elements of the Parameters and identifies the conditions under which the static aspects can be modified. The document clarifies the dimensionality object and defines new array elements that indicate use of absolute or relative values. The document clarifies minimum support for Parameters and array Parameters
History of document development: as a result of work started in August 2014, the core team (representatives from AmsterCHEM, Bryan Research & Engineering, US Environmental Protection Agency) within the Methods &Tools Special Interest Group reached consensus on August 5, 2015 on a document gathering errata and clarifications pertaining to Parameters. This document was submitted for review to a number of companies on August 5, 2015. The comments received by September 4, 2015 were collected, analyzed by the M&T SIG and answered to. Simultaneously, the M&T SIG modified the Parameter Errata and Clarifications document (final version on September 23, 2015) which was then submitted for public release to the Management Board on October 11, 2015.
