[Moims-dai] Information or data lifecycle vs Project lifecycle - incomplete monograph

I agree with David’s concerns. I think the need and focus should be on what the ‘project’ needs to do to ensure its information is ready for long term preservation.  To accomplish this would be a significant step forward and broadening it would be a distraction.  This does not mean that concerns for the Designated Community are to be ignored as this must be of concern to the project as it prepares its information for presentation to an archive, but a full consideration of possible future Designated Communities would get into archival activities. I think a project should include a description, at the proposal stage, of the Designated Community it has in mind.  This would provide a focus for the nature and amount of ‘additional information’ needed to accompany the primary data being submitted, and it would aid in the review by the project and others as to the adequacy of the total information to be preserved. That is how I see it.

I’m sorry but I’ll not be available for today’s telecon.

For example, the lifecycle elements are, as already noted by Don, John, and several others, more typical of a project lifecycle than a data or information lifecycle.   I had accepted an action to review and offer suggestions to improve Chapter 5 and it's associated table. I propose that the table should be recast to more properly reflect a Generic Data Lifecycle that accommodates longterm, potentially unending, data generation environments as well as situations where data lifecycle management is associated with and punctuated by short-term project level goals.   The generic data lifecycle emphasizes the data operations leading from initial or conceptual planning for data collection or generation, through to explicit freezing of a data package and final disposition.
