PAR Overview

Preservation Action Registries (PAR) is a project that aims to support the sharing of technical information on digital preservation across the global digital preservation community and between digital preservation systems. It aims to provide a common and consistent way to describe and execute preservation policies and actions at a technical level.

PAR provides

Typically, proprietary DP systems lack a common means to describe and execute preservation policies and actions. For example, Archivematica’s Format Policy Register (FPR) and Preservica’s Linked Data Registry (LDR) both define what tools and rules to use to execute specific DP actions but they are not interoperable. In a nutshell:

The aim of PAR is to overcome this problem by providing the means to connect different registries to exchange policy information about preservation actions. The model makes registry content accessible through a feature rich API using a distributed set of registries. In this way information can be made available from a range of source registries as well as via direct exchange between trusted peer institutions or systems.

PAR History

The PAR Project began as part of a project funded by Jisc in 2017, called Research Data Shared Services (RDSS), later renamed to Jisc Open Reserach Hub. The RDSS project provided hosted versions of both Archivematica and Preservica, and Jisc wanted a way to create a shared registry of preservation tools, rules, and actions across both systems.

THe PAR concept was first published in a paper presented at iPres 2018 in Boston.

PAR Today

PAR has evolved from a standing start to a standalone entity using the expertise and resources of a set of industry leading organisations to form the nucleus of the PAR core team

To add further credibility, Wikidp is in the process of connecting into the network as a significant trusted source partner. The core team is currently in discussion with other potential sources to expand the network over the course of the coming months.

As of April 2020, the OPF became the overall custodians of PAR with the aim of shifting the emphasis to create a more community focused program to help define development priorities as well as fostering community contribution.

The core software (v1.2.0) isis generally available. The high level roadmap for PAR is outlined in the Roadmap section.

The PAR Vision

The PAR vision is based on the establishment of a set of trusted sources that would provide the catalyst for information and good practice sharing across a set of proprietary Digital Preservation systems as well as the wider community. The end user would be able to determine the best / most appropriate preservation action sequences to fulfill their needs and have the opportunity to review, select or discard those options. Trusted sources could comprise:

It is envisaged that PAR would act as an enabler connecting users to sources of good practice allowing them to review singular, complex and compounded actions and via their own systems, proprietary applications and / or client tools elect to import those actions into their own local environments. Likewise they would have the ability to make their own complex workflows available to other members of the DP community ensuring that data is shared throughout the PAR enterprise.
