The XAR project aims to provide an easily extensible archive format. Important
design decisions include an easily extensible XML table of contents for random
access to archived files, storing the toc at the beginning of the archive
to allow for efficient handling of streamed archives, the ability to handle
files of arbitrarily large sizes, the ability to choose independent encodings
for individual files in the archive, the ability to store checksums for
individual files in both compressed and uncompressed form, and the ability
to query the table of content's rich meta-data. |
