RELEVANT METADATA TO PRESERVE “ALIEN” AIP
This article describes the development of Archives
Ready To Archival Information Packages (AIP)
Transmission a PREMIS Based Project (ARTAT).
Following the project approach, the starting phase
consisted of prototyping a layer conveying preservation
metadata, which can be encoded from the existing
archival systems, and exchanged with other repositories.
This layer called Preservation Metadata Layer (PML)
uses PREMIS semantics as the common language to
overcome archival systems differences, and to transmit
out of its original context, relevant preservation
information about content objects comprising an AIP.
Since a repository, following the OAIS reference model,
usually provides resources with metadata container
objects, the experiment performed an analysis on
commonly used container formats, in order to enable the
traceability of semantics from a local to extra-local
level, and the technological understandability of alien
AIPs. The analysis has allowed the definition of a PML
data model, laying the production of prototypes. The
adoption of common semantics, like PREMIS, supports
the opportunity of preserving correctly alien AIPs,
coming from different technological environments, and
hopefully enables the overcoming of obstacles to the
interoperability among diverse archival systems.
