Hi Wendy, These are very important questions and I would love to be involved in further discussions on the subject. For preservation metadata you might want to have a look at PREMIS <http://www.loc.gov/standards/premis/v3/> . But as you have pointed out, recording preservation metadata is one thing, and setting up proper preservation actions (review / retain / archive / delete) is a different thing. Should we aim to ever automate these decisions (as to delete the files or not?). If these decisions are not automated, what is more cost-beneficial: keeping everything forever (taking into account that the cost of storage will decrease) or manually reviewing the records? Or could we use some semi-automated models to improve our decision-making? We have our research repository (DSpace) already since 2005, so some of the records have been kept in our repository already for over 10 years. Just in the past year we have accepted over 340 data depositions. At the moment we are not deleting any records.

I have been reviewing the JISCMAIL lists for an indication of how institutions manage dataset retention. I note there seem to be no fields in the various metadata schema that deal specifically with retention dates and decisions. How do others manage research data retention please? Do you require depositors to specify the retention period required for their datasets; or a period after which there should be a review/delete/archive decision?
