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.
An ontology supporting planning, analysis, and simulation of evolving Digital Ecosystems
Digital Ecosystems (DEs) are interwoven networks of Digital Objects (DOs), policies, processes, services and user communities, within constantly changing and interacting environments. Their complex grown structures can be difficult to maintain and it can be hard to foresee the impact of planned and unplanned change. The PERICLES EU FP7 project developed the Digital Ecosystem Model […]
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 (http://pericles-project.eu/). 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: http://ontologydesignpatterns.org/wiki/Submissions:DigitalVideo
Monitoring Term Drift Based on Semantic Consistency in an Evolving Vector Field
The paper presents key outcomes of the PERICLES project in the area of semantic drift and, more specifically, proposes a novel methodology for monitoring semantic drifts and for evaluating the semantic consistency of clusters of terms.
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.
