Preservation Issues
- MS Powerpoint is a proprietary format. However, the specification is freely accessible at http://download.microsoft.com/download/0/B/E/0BE8BDD7-E5E8-422A-ABFD-4342ED7AD886/PowerPoint97-2007BinaryFileFormat(ppt)Specification.xps.
- Normalization to Portable Document Format/Archival (PDF/A) may be an acceptable preservation strategy in addition to normalization to ODF using Xena.
- For more information on the PDF/A format see Library of Congress Sustainability of Digital Formats: PDF/A-1.
- A list of tools used to convert files to PDF format is available at Codswallop technology + productivity blog.
