Multidimensional Approach to Preservation of Historical Audio Recordings

A Study of Chemical and Microbiological Degradation Mechanisms

summary

Based on an in-deep study of two Portuguese audio tape collections, PreservArt will correlate carrier material, mechanical issues, audio quality, chemical degradation, and microbiological contamination, and will consolidate terminology and existing SWO while proposing an effective and scalable relational database. PreservArt will develop an innovative diagnostic and documentation tool to assist professionals in historical audio preservation.


objectives

O1. Tape Assessment, Restoration, and Digitization

Assessment, restoration, and digitization of historical magnetic tapes to identify and treat degradation and ensure long-term access to their audio content.

O2. Material Characterization and Degradation Investigation

Scientific analysis of tape materials and contaminants to understand chemical and microbiological degradation and their impact on audio quality.

O3. Terminology, Ontology, and Database Design

Development of a standardized vocabulary, semantic ontology, and interoperable database to document and share knowledge on magnetic tape preservation.

O4. Diagnostic Tool and Dissemination

Creation of a comprehensive diagnostic tool and practical guidelines, supported by publications and outreach to professionals and institutions.


Work Packages

WP1 – Project Management and Coordination

Objective: Implement an efficient management and governance structure ensuring smooth project execution, compliance, and impact evaluation.
Main tasks: Establish management and reporting framework; recruit staff; organize kick-off meetings; ensure internal communication and risk management; monitor progress and evaluate results.

WP2 – Comprehensive Preservation and Restoration

Objective: Inspect, restore, digitize, and preserve historical magnetic tapes to ensure their long-term conservation and accessibility.
Main tasks: Inventory and assess tape conditions; restore damaged carriers; digitize audio; perform audio restoration and mastering; create archival copies; evaluate restoration quality.

WP3 – Materials and Ageing Characterisation and Microbiological Analysis

Objective: Analyse the chemical and biological composition of tapes to understand degradation processes and inform preservation strategies.
Main tasks: Characterize materials using advanced analytical techniques; assess ageing and the effects of restoration treatments; study microbiological contamination and its impact on audio stability.

WP4 – Relational Database and Platform Development

Objective: Develop a relational and interoperable database and digital platform to manage, publish, and share project data following FAIR principles.
Main tasks: Design the data model; implement the database on OmekaS; test and refine the system; integrate and publish data; connect to national and international platforms (ROSSIO, Europeana).

WP5 – Ontology and Terminology Development

Objective: Create a Semantic Web Ontology (SWO) and a Terminological Resource (TR) to standardize knowledge and support data interoperability.
Main tasks: Gather and review existing ontologies; define requirements; model the SWO (OWL) and TR (SKOS); evaluate, align, and publish both for open access and reuse.

WP6 – Results Consolidation, Communication, and Dissemination

Objective: Disseminate results and promote the project’s scientific, cultural, and social impact through communication, publications, and events.
Main tasks: Develop communication and dissemination strategy; prepare and distribute materials; consolidate results for FCT reports; engage with stakeholders; publish findings and host a final conference.
