Email preservation research

Preserving Email] (DPC Technology Watch Report 11-01, ISSN 2048-7916, Digital Preservation Coalition 2011), Chris Prom, University of Illinois.

• "In general, if an institution can get email into one of the MBOX or EML formats, it has taken a very big step on the road toward preserving email." (p.23)
• "XML conversion tools...can be very useful in achieving format neutrality. However, the author is aware of no general-purpose tools that are intended to facilitate the access, display, searching, or visualization of messages that have been migrated to XML. Until such tools have been developed – if they ever are – institutions will be forced to provide access to migrated messages using an email client of their choice or the user’s choice, recognizing that specific tools support different functionality." (p.23)
• "Institutions are beginning to implement the Email Account Schema [CERP], but few tools exist to query, display and render messages that are stored in the format. If the digital preservation community were to develop tools that support the Email Account Schema or a different XML standard for email, that XML format would be a likely candidate for adoption as an International Council on Archives or even an ISO standard."
