It may be useful for an EDRMS to enforce saving criteria on emails based on classification. Folders with a retention period of say two years could be stored in a proprietary format, but those with longer schedules could be saved into an open format.
This wasn't thought of in the latest Moreq2, perhaps they could put something along these lines into it: "where messages are saved in a proprietary format, the option should be available to save in multiple, including open, formats depending on the classification."
Keeping in mind that the majority of participants on this list are in the UK or elsewhere in the EU, these comments are correct... however, knowing that some of the participants are involved in this list because they work for
multi-nationals . or just want to know what's going on "across the pond", I'd encourage a broader perspective here.
