Introduction

Because the OLPC has limited storage and limited RAM, it is not a good idea to support every data format used on regular PCs. It makes more sense to use our PCs to convert data than to put that burden on the OLPC.

List of supported formats

TODO: This should become a table of format - activities supporting the format - a link to sample files for each file format.

  • Sound formats
    • Ogg Vorbis (supported by the Totem plugin for Browse). Sample file]
    • the Totem and Gnash plugins for Browse claim to support other formats, enter about:plugins in the Browse location field.
  • Video formats
    • Ogg Theora?
    • DV format ? (/usr/lib/libdv present)
  • General formats
    • XML
    • SQLite (a lightweight relational database that is included in Python 2.5)
    • Gnu gdbm (supported by Python's dbm module)
    • Berkeley db version 4.3.0.1 (supported by Python's bsddb module)
  • Compression formats
    • Uncompressed (this is listed because the JFFS2 filesystem on the OLPC will compress all compressable files)
    • GNU Zip (supported by Python's zlib module, and by Etoys)
