Abstract

Having confidence in the permanence of a digital resource requires a deep understanding of the preservation activities that will need to be performed throughout its lifetime, and an ability to plan and resource for those activities. The LIFE (Lifecycle Information for E-Literature) Project1 has advanced understanding of the short and long-term costs in this complex area, facilitating better planning, comparison and evaluation of digital lifecycles. The LIFE Project created a digital lifecycle model based on previous work undertaken on the lifecycles of paper-based materials. It applied the model to real-life collections, modelling their lifecycles and studying their constituent processes. The results were then used to estimate the costs of each element of the digital lifecycle. Organisations can now apply this process, enabling evaluation and refinement of their existing lifecycles and facilitating more effective planning for the preservation of newly acquired content. Phase 2 of the LIFE Project began in February 2007. It is evaluating and refining the models and methodology developed in the first phase of the project and developing lifecycle costings for a range of further case studies.
