Considerations for Digital Archivists and Librarians

Digital archivists and librarians may be interested in assessing the implementation of ZIM as an archival format. The format may present unique use-cases for certain workflows, like the production of access copies, or the development of a localized digital library.[1] WARC is the current ISO standard utilized for web archiving content. However, for simple HTML pages, the ZIM format may present a stable, lossless, and offline accessible alternative, which does not require web replay. The Web Replay of WARC files complicates indices of the files fixity, and may pose future challenges to assessments of archival validity.[2] Functional comparisons between the two formats might contribute to increased utilization of ZIM by archivists. One such project can be found here.
