This is very problematic for large public archives such as us here at The National Archives (UK). There are a number of issues at play, but I think the main one is seeing all institutions as having to preserve every themselves to allow independent understandability: in reality all institutions effectively sit within a broad federation of knowledge institutions and online infrastructure. We hold the records of government, the British Library holds published material, between the two (and potentially a lot of reading) you could probably independently understand everything we have. I took a wider look at this with a collaborative doctoral student here earlier in the year in what ended up as this blog post https://www.dpconline.org/blog/access-what-we-are-preserving (we’d submitted as a short paper for iPRES, but while the peer review comments were positive it didn’t quite make the available space on the programme).

As promised, I have uploaded a strawman text to review.oais.info<http://review.oais.info> to address the issue of general public v Designated Community.

Here is a copy of what I uploaded:

General Public v Designated Community

Many repositories have as part of their mission/mandate to serve the general public. In other words, the repository must disseminate any information that the Consumer is allowed to access without violating any restrictions on the release of the requested information. Some repositories have raised concerns about the tension between their requirements to serve the general public and the OAIS requirement to serve the repository’s Designated Community(ies).

The purposes for designating these two different classes of Consumers do have some overlap, but they also have some substantive differences. Indicating that a repository serves the general public means that anyone (with a few exceptions) can be a Consumer of the OAIS’ information. Indicating that a repository serves a particular Designated Community(ies) means that the members of the Designated Community may access any information the OAIS holds subject to any restrictions on the release of the data. NOTE: The OAIS Reference Model, and this standard, do not require repositories to limit their Consumers to members of their Designated Communities.

Designated Communities serve a distinct purpose related to the Long Term Preservation of the information held by the repository. Long Term Preservation is, “[t]he act of maintaining information, Independently Understandable by a Designated Community, and with evidence supporting its Authenticity, over the Long Term.” One of the mandatory responsibilities of an OAIS is to ensure that the information it holds is Independently Understandable by the Designated Community. The OAIS must periodically assess whether or not the information held for a specific Designated Community is still Independently Understandable by that Designated Community using their current Knowledge Base. If it is not, the OAIS must add additional Representation Information or PDI to make it so. If a repository collects information across many topics/domains, it may need to have multiple Designated Communities for the different topics/domains.

Under the OAIS Reference Model, and this standard, an OAIS does not have to ensure that its holdings are Independently Understandable to any Consumer outside its Designated Community(ies), though it may choose to try. In practical terms ensuring its holdings are and remain Independently Understandable to the general public would be a nearly impossible task. Consider, for example, maintaining enough Representation Information and PDI to make Einstein’s Theory of General Relativity Independently Understandable to a 6-year-old who reads only Korean. While many repositories will say they serve the general public, there are usually unwritten limits to the types of services the repository provides. By contrast, an OAIS must ensure that the information it provides remains Independently Understandable to the relevant Designated Community through time.

Looking forward to further discussion.
