NLA Digital collections: Statement of Preservation Intent
Collection Area: Maps
The Library's digital Maps collection includes born digital images from internal and external sources. As a largely published collection, Maps should consider the Preservation Intent of related institutions in determining intention to preserve.
Maps intend that:
- All Maps digital preservation masters should be retained in perpetuity, including all metadata. All technical properties should be maintained to the full extent possible.
- Derivative copies created for access should be maintained only for as long as useful; a new derivative version may be generated according to future access requirements.
- Born digital maps and map related material coming from external and internal sources should be treated similarly.
Other Issues:
- May include some material 'belonging' to other collection areas (e.g. Manuscripts) who need to be consulted.
- May include 'marginalia' and other textual data.
- Although Maps specify digital formats acceptable for acquisition through the CDP, this may change over time, requiring revision of preservation intent profile.
- Digitised items may be re-captured over time.
- Digital items come into the maps collection via three main collecting streams:
- Digitised internally through DCM;
- Digititised from an external source;
- Born digital, created from an external source; and
- A combinination of the later two catagories delivered via a carrier (physical, such as CD, DVD or logical, such as email). This content may or may not require different preservation actions.
- Some Image files which contain metadata may need to be modified/edited overtime. Alternatively, the metadata might have to be removed from the file and stored separately.
- There may be some material which is the responsibility of another agency to preserve.
- Does not consider NLA Maps staff created material.
