Example text

The archive is responsible for creating and preserving Provenance Information from the point of Ingest; however, earlier Provenance Information should be provided by the Producer. Provenance Information adds to the evidence to support Authenticity. Provenance may reasonably be divided into what we might term Technical Provenance – things that, for example, are recorded fairly automatically by software. This must be supplemented by Non-technical Provenance, by which we mean, for example, the information about the people who are in charge of the Content Information – the people who could perhaps fake the other PDI.

One might wonder why data includes physical objects such as a “moon rock specimen”. The answer should become clear later but in essence the answer is that to provide a logically complete solution to digital preservation one needs, eventually, to jump outside the digital, if only, for example, to read the label on the disk. As to the question of length of time we need to be concerned about, OAIS provides the following pair of definitions (the text in bold italics below is taken from OAIS): Long Term: A period of time long enough for there to be concern about the impacts of changing technologies, including support for new media and data formats, and of a changing Designated Community, on the information being held in an OAIS.

15 Three key concepts are embedded in the above definition namely: Authenticity: The degree to which a person (or system) may regard an object as what it is purported to be. The degree of Authenticity is judged on the basis of evidence. There will be much more to say about authenticity in Chap. 13, where the whole chapter is devoted to it. Independently Understandable: A characteristic of information that is sufficiently complete to allow it to be interpreted, understood and used by the Designated Community without having to resort to special resources not widely available, including named individuals.
