  1. Characterisation Adrian Brown The National Archives, UK

  2. Develop tools and services to characterise the significant properties of digital objects, to support: Development of preservation plans Validation of preservation actions (evaluating change) The subproject considers: Representation properties Inherent properties Overview

  3. To deliver: Methodologies for describing significant properties Tools and services for automating measurement and comparison of these properties Recommendations for improving the preservation characteristics of digital object types Aims & Objectives

  4. Aims & Objectives

  5. Achievements (Year 1) Characterisation registry Property description and extraction methodology and tools Characterisation tool framework

  6. First iteration registry (bringing PRONOM to its next generation) Persistent Unique Identifier scheme for registry information Support for registry-driven characterisation tool framework Characterisation registry

  7. Extensible Characterisation Description Language (XCDL) Extensible Characterisation Extraction Language (XCEL) Describing and extracting characteristics
