Many digital preservation projects are funded by grants or donation. Analogous to naming a reading room, marking a shelf with a brass plaque, or placing a sticker in the book, I think it's important to recognize these contributions with something. Metadata seems like a good place to record this. For example,
<agent><agentName>Digital forensics workstation</agentName><donor>Generous foundation</donor><agent>
or
<event><eventType>Digitization</eventType><funder>NHPRC</funder></event>
or
<collection><name>Famous writer's hard drive</name><creator>Famous writer</creator><donor>Person who purchased collection at auction</donor></collection>
I scanned through PREMIS, METS, and EAD, but couldn't find anything. Does anyone record this information in a structured way and can they share advice on how they do it?
