Abstract:
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.

This article describes the development of the project named Archives Ready To AIP Transmission a PREMIS Based Project (ARTAT), that took place, from March to April 2010. The goal of ARTAT is to experiment with the adoption of a common preservation metadata standard as an interchange language in a network of cooperating organizations that need to exchange digital resources with the mutual objective of preserving them in the long term.
The project in pursuing its initial objectives, has experimented with the definition of a Preservation Metadata Layer (PML) following the PREMIS standard Data Dictionary (DD) specifications that will integrate repositories' preservation metadata. The exported repositories' AIPs including a PML will be received by selected repositories and ingested into their archival systems. Hopefully, because of the common PREMIS knowledge base, the receiving repositories will be able to locate information objects and data objects contained in the AIPs transmitted by the originating repositories. To date, the project consisted of testing the Preservation Metadata Layer prototype produced from representative samples, selected from the initial participant repositories.
The critical path analysis, which was conducted on the PML prototypes, will be traced in order to support the ultimate objective of transmitting resources destined for preservation in a repository other than the originating repository. It is assumed that the devised layer will be agnostic about the originating archival systems, as well as about the receiving archival systems. A successful transmission can be accomplished as long as both of the repositories in the transfer can manage XML conforming to the PREMIS framework. The milestones that will be explained below aim to test the feasibility of inventing a layer which contains all relevant information for the receiving repository to offer long term preservation services in the foreseeable future.
More information about aim, objectives, tools and methodologies of the project are available on the Fondazione Rinascimento Digitale website which supported this project and the Italian PREMIS community (http://www.rinascimentodigitale.it/projects-artat.phtml).
