    1. 1. Preservation Planning An Overview Hans Hofman Planets project, Training Vilnius, 3 October 2007
    2. 2. Overview <ul><li>What is the problem? Defining the issues </li></ul><ul><li>The scope and role of Preservation Planning </li></ul><ul><li>The Planets approach </li></ul><ul><ul><li>The organisational/ business context </li></ul></ul><ul><ul><li>Usage requirements and collection profiles </li></ul></ul><ul><ul><li>Preservation plans and preservation actions </li></ul></ul>
    3. 3. Why Preservation Planning? <ul><li>Who are the stakeholders? </li></ul><ul><li>What is the issue? Why important? </li></ul><ul><li>What are the objectives? </li></ul>
    4. 4. Stakeholders <ul><li>Memory institutions (‘content holders’) </li></ul><ul><li>(Scientific) data centres </li></ul><ul><li>Government organisations </li></ul><ul><li>Business companies </li></ul><ul><li>Individuals </li></ul>
    5. 5. The issue / challenge <ul><li>The enormous and rapidly increasing amount of digital information </li></ul><ul><ul><li>Fragile resources </li></ul></ul><ul><li>The rapid evolution in technology </li></ul><ul><li>The risk of obsolescence and therefore corruption and/or loss of valuable information </li></ul><ul><li>(Pro-)active and ongoing attention / maintenance required </li></ul><ul><li>Potential solutions: still fragmented </li></ul><ul><ul><li>infrastructure </li></ul></ul><ul><ul><li>not comprehensive </li></ul></ul>
    6. 6. Objectives of Preservation Planning <ul><li>To identify and analyse the organisational context </li></ul><ul><ul><li>including a risk assessment </li></ul></ul><ul><ul><li>define a framework for preservation (?) </li></ul></ul><ul><li>To support decision-making about digital preservation including </li></ul><ul><ul><li>Identifying criteria for preservation within that context </li></ul></ul><ul><ul><li>Defining workflow for evaluating/ defining preservation plans </li></ul></ul><ul><ul><li>Developing methodologies for assessing the risks of applying different preservation strategies for different types of digital objects </li></ul></ul><ul><li>To enable formulation, evaluation and execution of high-quality and cost-effective preservation plans that suit the organisational (e.g. repository) needs </li></ul>
    7. 7. What is Preservation Planning? <ul><li>Defining criteria for preservation of specific digital objects (in the collection) based on risk analysis in a defined (business) context </li></ul><ul><li>Following a systematic and structured workflow/ procedure in making decisions about the best possible approaches given the organisational context and the content of the repository </li></ul><ul><li>Defining one or more appropriate preservation plan(s) </li></ul><ul><ul><li>depending on the types of objects and available strategies </li></ul></ul><ul><li>Execute those plans when needed, and </li></ul><ul><li>Be able to assess the quality of the results </li></ul><ul><li>Document all these steps in order to be accountable </li></ul><ul><li>Issue: scope includes preservation policy? </li></ul>
    8. 8. Preservation policy: what is it? <ul><li>Framework for maintaining digital objects over time </li></ul><ul><li>Context (positioning the institution, legal and social context, user needs, …) </li></ul><ul><li>Scope and objectives </li></ul><ul><li>Principles </li></ul><ul><li>Concepts </li></ul><ul><li>Roles and responsibilities </li></ul><ul><li>Strategies, rules, standards, and procedures </li></ul><ul><li>… . </li></ul>
    9. 9. From preservation policy to action Policy/framework preservation planning process translate into executable workflow Context: mandate, business Plan Action/ execution Feedback/evaluation
