A Model-driven Approach to Preservation of Complex Digital Objects in Space Science

The paper discusses problems in preserving complex digital objects generated by experiments in space science. It describes PERICLES model-driven approach, how it can be applied to the automation of preservation processes such as technical appraisal and the relationship to the big data theme.

The Resource Action Language: Towards Designing Reactive RDF Stores

This paper introduces the main principles of ReAL (Resource Action Language), a language developed in the context of PERICLES model-driven approach to address the need for systems to react to the stimuli received from continually evolving environments. In an interconnected world such as the one envisioned by pervasive computing, systems should be able to react […]

PREMIS Data Dictionary for Preservation Metadata, Version 3.0

The PREMIS Data Dictionary and its supporting documentation is a comprehensive, practical resource for implementing preservation metadata in digital archiving systems. The Data Dictionary is built on a data model that defines five entities: Intellectual Entities, Objects, Events, Rights, and Agents. Each semantic unit defined in the Data Dictionary is a property of one of […]

PERICLES – Space Science Portal

This poster presents the developments carried out by the PERICLES project partner Space Applications Services to augment the operational workflow at B.USOC. This enhances its preservation capabilities and ensures that the experiment outputs, and their metadata, can be easily accessed and exploited by an as wide as possible scientific community. At the same time it […]

PERICLES – Policy Editor

This poster presents the Policy Editor that is a development by Space Applications Services in the PERICLES project ( The Policy Editor allows to create, refine and update a coherent and consistent set of policies for long term data preservation. The used policy model, whereof the properties can be defined or modified using the Policy […]

A pragmatic approach to significant environment information collection to support object reuse

This paper introduces the concept of Significant Environment Information (SEI), which takes into account the dependencies of the digital object on external information for specific purposes and significance weights. This information supports object use and reuse, e.g. for a better long-term preservation of data. The paper also introduces the PERICLES Extraction Tool (PET), an open […]

An Ontology Design Pattern for Digital Video

The paper proposes an Ontology Design Pattern (ODP) for modelling digital video resources, which was developed in the context of the PERICLES domain ontologies for Art & Media. The ODP can be found at this address:

Ontology-based Representation of Context of Use in Digital Preservation

The paper proposes a novel, ontology-based representation for modelling context and use-context of digital resources in the digital preservation field. At the core of the proposed representation lies the Linked Resource Model (LRM), an upper ontology for modelling dependencies between digital objects.

Studying the Cohesion Evolution of Genes Related to Chronic Lymphocytic Leukemia Using Semantic Similarity in Gene Ontology and Self-Organizing Maps

This paper offers an interesting overview on the application of some of PERICLES results in the biomedicine domain. In particular, this publication deploys an ontology-based semantic similarity combined with self-organizing maps for studying the temporal evolution of cohesion among Chronic Lymphocytic Leukemia (CLL) -related genes and the extracted information. More information on the open-source tool […]

A Framework for Measuring Semantic Drift in Ontologies

Semantic drift is an active field of research, aiming to identify and measure changes in ontologies across time and versions, closely related to ontology evolution. However, practical and widely adopted methods that are directly applicable to Semantic Web constructs have yet to emerge. Building upon and extending existing work, this paper presents a framework for […]
