OAIS STANDARD MODEL FOR DIGITAL PRESERVATION OAIS (Open Archival Information System) is a reference model for creation of a digital repository. ISO 14721:2012. Piql Preservation Services has been designed to match the OAIS entities. INFORMATION PACKAGE - PIQL Our main differentiator is the self-contained informa- tion package piqlFilm: File(s) + (Source code, semantic document, file format(s) specification) + Metadata (PDI 1 ) Piql writes the Archival Information Package (AIP) onto the film and preserves the information ensuring its un- derstanding and accessibility any time in the future, re- gardless of the evolving technologies. We can also provide Comprehensive Preservation 2 , if the data owner wants to preserve proprietary or unsus- 1 PDI: Preservation Description 2 Comprehensive Preservation: Includes Bit Preservation 3 plus meta- data ensuring accessibility to the data in the future.

tainable file formats. To ensure maximum understand- ability and integrity, Piql can also preserve a visual repre- sentation of the file content. INGEST Piql receives information from the data owners and pre- pares it for storage. Part of the preparations is to per- form a file format normalization process: • Virus checking • File format identification • Validation • Metadata extraction or automatic metadata population. We then add all representation information and PDI metadata to be written on film along with the data con- tent. ARCHIVAL STORAGE The Piql Preservation System accepts AIPs, writes them to film for long term storage, checks for errors, and pro- vides requested AIPs to the Access entity.
