Preservation Intent - Maps

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.
