In the nowadays world characterized by complexity, the digital systems for archival and bibliographic description are, especially in Italy, a faithful mirror of too many horizontal (among bodies with national functions) and vertical (among central and peripheral levels) complications. The integration of data sets conceived according to the up-to-date conceptual domain models would simplify the dynamics of representation, improve user experiences, and optimize the environmental costs of computing infrastructures. The concepts to be shared should relate to agents (individual or collective), places, and chronological data, deepening on how to address the more complex issues opened by things. This paper introduces three possible scenarios of semantic cooperation between archivists and librarians, not necessarily alternative: activating a conceptual matching through common entities, relying on a neutral semantic data infrastructure such as Wikidata, or, finally, developing a transversal core ontology. Hoping that disciplinary boundaries will not impede cooperation, two types of impediments must be considered: the organizational one (bottom-up, top-down, or a virtuous synergy between the two organizational models?) and the crucial issue of offering easy-to-use interfaces to end users, not only constituted by software agents.

Focusing on olive oil sector in central Italy, this paper proposes a decision support system for olive growers in order to: i) identify the optimal crop management in the hypothesis of maximizing gross farm income and maximizing a landscape integrity index; ii) simulate the effects of different policy and market scenarios. Results from multi-objective integer optimization models showed that the solution obtained by maximizing the gross income foresees the intensive crop management and the complete allocation of the farm area to newly planted olive groves. The traditional crop management is chosen when the landscape integrity index is maximized. However, only a 30% increase of the Extra Virgin Olive Oil price from ancient and traditionally managed olive groves could ensure their complete maintenance. [ABSTRACT FROM AUTHOR]

After an excursus on the peculiarity of the Sardinian language and the difference between a language and a dialect, the paper analyses the changes applied to the treatment of Sardinian language in different Dewey Decimal Classification editions. [ABSTRACT FROM AUTHOR]
