The Errata and Clarifications document for the Persistence Common Interface specification 1.0 provides clarification on the use of the COM persistence interfaces in the context of CAPE-OPEN applications. The document provides background on COM persistence, clarifies the responsibilities of the PME and PMCs during persistence, enumerates what a PMC should save and restore, discusses the fall-back persistence procedure and defines the data types supported by IPropertyBag implementations.
History of document development: the core team (representatives from AmsterCHEM, Bryan Research & Engineering, US Environmental Proctection Agency) within the Methods &Tools Special Interest Group (M&T SIG) started work on the document in May 2015 and reached consensus on January 6, 2016 on a document gathering errata and clarifications pertaining to persistence. This document was submitted for review to a number of CO-LaN members. The comments received by end of February 2016 were collected, analyzed by the M&T SIG and answered to. Simultaneously, the M&T SIG modified the Persistence Errata and Clarifications document (final version on May 4, 2016) which was then submitted for public release to the Management Board.
