An AIP (Archival Information Package) is the digital equivalent of an archival item such as a book, a record album, or a motion picture. It consists of multiple data files that contain the digitised content of the archival item. In addition to the data files, the AIP contains metadata that describes the structure, content, and meaning of the data files. The data files and metadata are packaged (encapsulated) either logically or physically as an entity. AIPs are used to transmit and/or store archival objects within a digital repository system.
AQL stands for Acceptance Quality Limit. It indicates the average number of faults in a batch that is still acceptable (in %). The AQL number depends on the sequence of faults in the batch and is usually stipulated in the contract.
ICE (Image Correction and Enhancement) is a process to remove dust and scratches, in which the infra-red channel of a scanner is applied to analyse the position of dust particles or scratches on negatives or slides.
The International Standard Archival Authority Record ISAAR (for Corporate Bodies, Persons and Families) is a guideline for the description of the provenance of records. Thereby, the obligation of documenting provenance, context and use of archival material is standardised.
The International Standard Archival Description (General) is an international standard for the description (indexing) of archival material.
Smart Removal of Defects (SRD) is a process to remove dust and scratches, whereas iSRD also uses the infra-red channel of the scanner in order to detect the position of dust particles or scratches on negatives and slides. In this process the image is scanned twice (infra-red and normal RGB), while the removal of defects is calculated via the infra-red channel.
Nesting signifies the variable layout of a fiche, on which several images of various sizes are recorded. The advantage of this procedure is the reduced space (costs) and the retention of a chronological signature order.
OAIS (Open Archival Information System) is an internationally recognised reference model for the definition and standardisation of digital archiving. It has also been published as ISO 14721. Among other things it describes the norms of archival information packages (AIP) and submission information packages (SIP).
The digital Submission Information Package (SIP) is based on the OAIS reference model and, according to the Federal Archives, it contains two separate parts that always have to be submitted together: the header including all metadata (describing information concerning the package and the primary data) in XML format and the content including the primary data.
