File Formats and Preservation Activities
Below is a list of file formats currently in the Academic Commons Departmental Collections. Files are checked daily for checksum accuracy, and are backed up by WITS. File formats are reviewed every five years for readability.
|Format||Bitstream Count||Support Level|
|Microsoft Excel XML||54||Unknown|
|Microsoft Powerpoint XML||8||Known|
|Microsoft Word XML||120||Known|
NOTE: Text items are mostly extracted text from other formats
File formats last reviewed in 2012. Formats classed 'Unknown' included: .mp3, .vob, mp4, .zip (usually source code, or tarred and compressed copies of jpeg image cds), .wmv . The long term accessibility of these formats is unclear. See the File Preservation Policy page form more information on supported formats.
Ideally we would like to know more detail about these formats, e.g. versions of Word in use. This may be possible with the BitstreamFormat Renovation dspace extension, though it is not officially released, and may not be compatible with current versions of DSpace.
