Impermanence

The Planets Time Capsule: "is a metal box that contains at risk digital objects: a JPEG photograph, a message in Java source code, a short film in .MOV format, a web-page in HTML and a brochure in PDF.

Each object is stored in its original format and a new format more suitable for long-term preservation such as PDF/A, TIFF, JPEG2000 and MPEG4. The objects are stored on media that range from paper, microfilm and floppy discs to CDs, DVDs and flash-drives and HDDs.

Inside the box are the original and new objects, storage media, and some reading devices. It also includes conversion tools that were used to migrate the objects as well as software to open and view/use these objects and supporting software all the way down to an operating system; descriptions of the file formats, of the file systems and encodings used on the storage media; and description of all these objects and their relationship to supporting technology and recognised standards."
