Inspired by the “Knowledge Base” definition of the Open Archival Information System: “A set of information, incorporated by a person or system, that allows that person or system to understand received information”, we developed a mapping model for a) capturing the knowledge base of the digital preservation metadata, represented by the PREMIS Data Dictionary, and b) generating a SKOS vocabulary, that represents the PREMIS Knowledge Base.

Cyber-physical Social System (CPSS) are complex systems that span the boundaries of the cyber, physical and social spheres. They play an important role in a variety of domains ranging from industry to smart city applications. As such, these systems necessarily need to take into account, combine and make sense of heterogeneous data sources from legacy systems, from the physical layer and also the social groups that are part of/use the system.

Modern software applications increasingly benefit from accessing the multifarious and heterogeneous Web of Data, thanks to the use of web APIs and Linked Data principles. In previous work, the authors proposed a platform to develop applications consuming Linked Data in a declarative and modular way. This paper describes in detail the functional language the platform gives access to, which is based on SPARQL (the standard query language for Linked Data) and on the dataflow paradigm.

The paper explores the strategies and methods for preserving Linked Open Data (LOD). To this aim it first presents an
overview of the main scientific initiatives that have dealt with this topic. Then it describes some digital technologies that may
result useful for preserving LOD, providing some insights on their application to LOD. It also provides a concrete example
of implementation of the Semantic Web technologies for preserving Linked Data. Finally, it suggests some specific themes

The Principle of Provenance is a pillar of Archival Science. In its very early stages it mostly meant not to intermingle documents from different origins. This view has been challenged in the past fifty years: archival provenance has moved from a simplistic one-to-one relationship to a multi-dimensional concept based on a network of relationships between objects, agents and functions.

Il capitolo affronta i problemi dell’interoperabilità semantica tra le collezioni digitali gestite dalle istituzioni della memoria, in particolare da gallerie e musei, oltre che da biblioteche e archivi, e si concentra sull’ontologia CIDOC-CRM, adottata a livello internazionale come strumento per lo scambio e l’integrazione delle descrizioni e delle informazioni tra fonti eterogenee del patrimonio culturale. Si illustrano le caratteristiche dell’ontologia CIDOC e la ricchezza delle proprietà che presenta.
